Appeal from the Judgment Entered May 12, 2014 

In the Court of Common Pleas of Allegheny County 

Civil Division at No(s): GD-09-013201 

BEFORE: OLSON, WECHT AND STRASSBURGER,* JJ. 

MEMORANDUM BY OLSON, J.: FILED APRIL 21, 2015 

 

Appellants, Frank C. Mamone (“Mr. Mamone”) and Linda Mamone 

(“Mrs. Mamone”), appeal from the judgment entered on May 12, 2014. We 

affirm. 

 The factual background of this case is as follows. According to Mrs. 

Mamone, at approximately 6:30 a.m. on July 20, 2007, she was tossing and 

turning in bed at which time Mr. Mamone asked her if she were okay. At 

7:00 a.m., Mrs. Mamone awoke and discovered that Mr. Mamone, who was 

lying next to her, was unresponsive. Mr. Mamone was transported via 

ambulance to St. Clair Memorial Hospital (“St. Clair”). Mr. Mamone arrived 

at St. Clair at 7:56 a.m. At 8:00 a.m., nurse Mellissa Vietmeier (“Ms. 
J-A04014-15 

- 2 - 

Vietmeier”) administered the National Institute of Health Stroke Scale 

(“NIHSS”) test. She documented a score of 16. Dr. Owen T. Traynor (“Dr. 

Traynor”) began to care for Mr. Mamone at 8:07 a.m. Dr. Traynor was 

employed by UMPC Emergency Medicine, Inc. (“UPMC”). At 8:15 a.m., Mrs. 

Mamone arrived at St. Clair after driving herself. 

 At 8:50 a.m., Dr. Traynor ordered a CT scan of Mr. Mamone’s brain. 

At 9:07 a.m., the radiologist informed Dr. Traynor that the CT scan was 

negative. At 11:26 a.m., Dr. Traynor requested a neurological consultation. 

After this consultation, Mr. Mamone was transferred to UPMC PresbyterianShadyside Hospital (“Shadyside”) for surgery to remove the blood clot in his 

brain. As a result of the stroke, Mr. Mamone suffered permanent brain 

damage. 

 We also briefly review relevant medical issues in this case. Generally, 

there are two types of strokes, ischemic and hemorrhagic. Ischemic strokes 

are caused by a blockage in a blood vessel in the brain while hemorrhagic 

strokes are caused by the rupture of a blood vessel in the brain. It is 

undisputed that the standard of care for the treatment of ischemic strokes, 

both in July 2007 and presently, calls for the administration of recombinant 

tissue plasminogen activator (“tPA”) within three hours of the patient last 

being neurologically normal. When a patient wakes up with stroke 

symptoms, it is called a wake-up stroke and the patient is considered to 

have last been neurologically normal when he or she fell asleep as there is 
J-A04014-15 

- 3 - 

no way of knowing when the stroke began. The tPA treatment is 

administered intravenously and generally is able to dissolve the clot in the 

blood vessel. However, tPA cannot be safely administered to patients 

suffering from a hemorrhagic stroke nor to patients that have been suffering 

an ischemic stroke for longer than three hours. 

 The relevant procedural history of this case is as follows. Appellants 

commenced this action on July 22, 2009 by filing a writ of summons. On 

October 19, 2009, Appellants filed a complaint against, inter alia, Dr. 

Traynor, St. Clair, and UPMC (collectively “Defendants”). Appellants’ 

complaint alleged that Dr. Traynor committed medical malpractice. The 

complaint further alleged that St. Clair and UPMC were vicariously liable for 

Dr. Traynor’s malpractice. 

On or before September 18, 2012, Appellants served Defendants with 

several expert reports, inter alia, an expert report authored by Dr. Steven R. 

Levine (“Dr. Levine”). On August 28, 2013, Defendants disclosed that Dr. 

James M. Gebel, Jr. (“Dr. Gebel”) would serve as an expert witness on their 

behalf.1 On September 23, 2013, Dr. Gebel authored an expert report. 

Appellants filed a motion to compel and, on October 2, 2013, Appellants 

 

1

 The large gap between the filing of Appellants’ expert report and 

Defendants’ disclosure of Dr. Gebel as an expert was caused by a procedural 

irregularity. Trial was originally scheduled to commence in March 2013 and 

Appellants’ report was filed based upon that trial date. Thereafter, however, 

Appellants requested a continuance. Trial was then rescheduled for October 

2013 and Defendants’ disclosure was made pursuant to the deadlines 

established for the new trial date. 
J-A04014-15

received Dr. Gebel’s expert report. On October 9, 2013, Appellants filed Dr. 

Levine’s supplemental expert report. On October 24, 2013, Defendants filed 

Dr. Gebel’s supplemental expert report.2 

On October 25, 2013, Defendants moved to quash notices to 

attend/notices to produce directed to representatives of St. Clair and UPMC. 

That same day, Defendants moved in limine to prohibit cross-examination of 

Dr. Traynor regarding any authoritative source. On October 28, 2013, 

Appellants moved in limine to strike Dr. Gebel’s supplemental expert report. 

Jury selection occurred on October 28, 2013. On October 29, 2013, the trial 

court denied Appellants’ motion in limine, granted Defendants’ motion in 

limine in part (permitting cross-examination of Dr. Traynor using only the 

American Stroke Association’s Guidelines for the Early Management of Adults 

with Ischemic Stroke (“ASA Guidelines”)), and granted Defendants’ motions 

to quash. That same day, the jury was sworn and trial commenced. On 

November 6, 2013, the jury returned a verdict in favor of Defendants. The 

jury concluded that Dr. Traynor did not breach the standard of care.

 Appellants argue that this supplemental expert report was filed at 2:00 

p.m. on October 25, 2013. The certified record reveals, however, that the 

supplemental expert report was filed at 2:50 p.m. on October 24, 2013. 

See Defendants’ Supplemental Pretrial Statement, 10/24/13, at 1.

Appellants filed a post-trial motion on November 15, 2013. The trial court 

denied the post-trial motion on April 24, 2014. This timely appeal followed.3 

 Appellants present four issues for our review: 

1. Whether the trial court erred by refusing to grant [Appellants’] 

motion to strike/motion in limine to preclude testimony of [Dr. 

Gebel] as to matters set forth in a supplemental report dated 

October 22, 2013, served on the eve of trial, identifying new and 

difficult medical issues that [Appellants] were required to 

address at trial without a reasonable time to consult with 

medical experts[?] 

2. Whether the trial court erred by permitting Dr. Gebel to testify to 

a congenital absence or abnormality of [Mr. Mamone’s] posterior 

communicating artery, which went beyond the fair scope of both 

his original and supplemental reports[?] 

3. Whether the trial court erred by granting Defendants’ motion in 

limine limiting [Appellants’] cross-examination of [Dr. Traynor] 

and prohibiting [Appellants] from cross-examining Dr. Traynor 

as to any authoritative sources other than the [ASA Guidelines?] 

4. Whether the trial court erred by granting Defendants’ motions to 

quash notices to attend/notices to produce directed to 

designated representatives of [St. Clair and UPMC] which sought 

testimony related to a staffing agreement between [St. Clair and 

UPMC] and the operation of [St. Clair’s] emergency 

department[?]

 In their first issue, Appellants contend that the trial court erred by 

denying their motion in limine to strike Dr. Gebel’s supplemental expert

 On May 16, 2014, the trial court ordered Appellants to file a concise 

statement of errors complained of on appeal (“concise statement”). See

Pa.R.A.P. 1925(b). On May 22, 2014, Appellants filed their concise 

statement. On August 19, 2014, the trial court issued its Rule 1925(a) 

opinion. All issues raised on appeal were included in Appellants’ concise 

statement.

report. “When reviewing a ruling on a motion in limine, we apply an 

evidentiary abuse of discretion standard of review. The admission of 

evidence is committed to the sound discretion of the trial court and our 

review is for an abuse of discretion.” Commonwealth v. Parker, 104 A.3d 

17, 21 (Pa. Super. 2014) (citation omitted). “An abuse of discretion occurs 

where the law is overridden or misapplied, or the judgment exercised is 

manifestly unreasonable, or the result of partiality, prejudice, bias, or ill will, 

as shown by the evidence or the record.” Commonwealth v. Adams, 104 

A.3d 511, 517 (Pa. 2014) (internal quotation marks and citation omitted). 

 Pennsylvania Rule of Civil Procedure 4003.5 provides, in relevant part, 

[(a)(1)(B)] A party may through interrogatories require . . . the 

other party to have each expert so identified state the substance 

of the facts and opinions to which the expert is expected to 

testify and a summary of the grounds for each opinion. The 

party answering the interrogatories may file as his or her answer 

a report of the expert or have the interrogatories answered by 

the expert. 

* * * 

(c) To the extent that the facts known or opinions held by an 

expert have been developed in discovery proceedings under 

subdivision (a)(1) or (2) of this rule, the direct testimony of the 

expert at the trial may not be inconsistent with or go beyond the 

fair scope of his or her testimony in the discovery proceedings as 

set forth in the deposition, answer to an interrogatory, separate 

report, or supplement thereto. 

Pa.R.C.P. 4003.5. 

 Furthermore, 

An expert report . . . shall encompass all issues in the liability 

phase of the case, including issues of professional negligence 
J-A04014-15

and causation of harm, for which a party to whom a request has 

been directed will offer expert testimony at trial in support of 

claims made against the requesting party or in support of 

defenses raised to the requesting party’s claims. The report 

shall reflect the best information available to the party producing 

the report at the time it is produced. 

Pa.R.C.P. 1042.27(b)(2). 

 Finally, with respect to the filing and production of expert reports prior 

to trial, the local rules of the Court of Common Pleas of Allegheny County 

provide that: 

After a plaintiff has filed a praecipe requesting that the case be 

placed on the next available trial list, each other party in the 

case shall file within [60] days expert reports summarizing all 

expert testimony that will be offered by that party to support the 

defenses to the plaintiff’s claims and to support any claims and 

defenses involving other parties. After [60] days, each other 

party’s right to file additional/supplemental reports is subject to 

the provisions of subsection (7)(d) of this local rule. 

(d)(i) A party may file a supplemental expert report which 

responds to an opposing expert report within [60] days after the 

opposing expert report was filed. 

(ii) Except as provided in subsection (7)(d)(i), a party may not 

file a supplemental expert report which introduces a new theory 

of liability of causation or a new defense without leave of Court 

for good cause shown. 

(iii) Except as provided in subsection (7)(d)(i), a party may not 

subsequently file an expert report prepared by a new expert 

without leave of Court for good cause shown. 

Allegheny County Local Rule 4003.5(7). 

 Appellants contend that Dr. Gebel’s supplemental expert report 

violated Local Rule 4003.5(7)(d)(ii) because it introduced new defenses. 

This argument, however, fails to recognize that Dr. Gebel’s supplemental 
J-A04014-15 

- 8 - 

expert report was filed in response to Dr. Levine’s October 9, 2013 

supplemental expert report – which was filed two weeks prior to the 

commencement of trial. The new topics addressed in Dr. Gebel’s 

supplemental expert report were in direct response to Dr. Levine’s 

supplemental expert report and, therefore, Defendants were not required to 

seek leave of court to file Dr. Gebel’s supplemental expert report. 

 In his supplemental expert report, Dr. Levine opined that, “If, [] as Dr. 

Gebel opines, [Mr. Mamone] was far outside the [three]-hour window with a 

wake-up stroke then his head CT scan would almost certainly have evidence 

of ischemic changes more obvious than those seen on the imaging.” Dr. 

Levine Supplemental Expert Report, 10/9/13, at 3. Dr. Levine further 

opined that “[T]he conclusion that Dr. Gebel reaches about being ‘essentially 

100% certain’ that [Mr. Mamone] would not have achieved successful 

recanalization had such a therapy been attempted is not accurate[.]” Id. at 

5. Dr. Levine similarly opined that, “The negligence of Dr. Traynor caused 

and/or increased [Mr. Mamone’s] risk of developing the type of permanent 

deficits that he developed subsequent to and as a direct result of his 

ischemic stroke[.]” Id. at 2. 

 Appellants primarily object to Dr. Gebel’s opinions, in his supplemental 

report, regarding imaging studies that were done at Shadyside. These 

opinions, however, were in direct response to Dr. Levine’s supplemental 

expert report. Specifically, Dr. Gebel stated that the ischemic changes 
J-A04014-15 

- 9 - 

referenced by Dr. Levine were actually present in the CT scans and 

supported his opinion that Mr. Mamone experienced a wake-up stroke and 

the alleged interaction with Mrs. Mamone at 6:30 a.m. did not constitute the 

last time Mr. Mamone was neurologically normal. Dr. Gebel’s opinions with 

respect to the scans at Shadyside also refuted Dr. Levine’s opinion that 

administration of tPA would likely have prevented the injuries that Mr. 

Mamone suffered as a result of the stroke. 

We find instructive this Court’s decision in Keffer v. Bob Nolan’s 

Auto Serv., Inc., 59 A.3d 621 (Pa. Super. 2012), appeal denied, 69 A.3d 

602 (Pa. 2013). In that case, the defense expert filed a supplemental expert 

report which expressed opinions in response to the plaintiff’s expert’s 

supplemental report. The plaintiff thereafter moved to strike the defense 

expert’s supplemental report and to bar the defense expert from testifying 

as to the newly expressed opinions. This Court held that: 

The record is devoid of any evidence of a willful violation of the 

discovery rules or bad faith by the [d]efendants. The 

[d]efendants did not hide the identity of their expert and did not 

attempt a “trial by ambush.” On the contrary, [the] 

supplemental report was necessary only because [plaintiff’s] 

supplemental report introduced new issues in responding to [the 

defense expert’s] two prior reports. 

Keffer, 59 A.3d at 654. 

The same thing occurred in this case. Dr. Levine’s supplemental 

expert report included new opinions in response to Dr. Gebel’s original 

expert report. Dr. Gebel therefore responded by filing a supplemental 
J-A04014-15 

- 10 - 

expert report that addressed Dr. Levine’s new opinions. Such a practice has 

become commonplace in today’s civil litigation, particularly in medical 

malpractice litigation. It does not amount to trial by ambush; rather, it 

permits both parties to narrow the issues for trial by highlighting the 

opinions that will be offered by expert witnesses for the factfinder’s 

consideration. As Dr. Gebel’s supplemental expert report was a legitimate 

response to Dr. Levine’s supplemental expert report, the trial court did not 

abuse its discretion in denying Appellants’ motion to strike Dr. Gebel’s 

supplemental expert report. 

 Furthermore, even if the trial court erred by denying Appellants’ 

motion in limine, that error was harmless. “An error is harmless if the court 

determines that the error could not have contributed to the verdict.” 

Bensinger v. Univ. of Pittsburgh Med. Ctr., 98 A.3d 672, 683 n.12 (Pa. 

Super. 2014) (internal alterations and citation omitted). Dr. Gebel’s 

supplemental expert report is focused primarily on causation, not the 

standard of care or any departure therefrom. Specifically, Dr. Gebel’s 

supplemental expert report discusses six discrete factors. The report 

summarizes these six factors and states that “[t]he only reasonable 

conclusion is that [Mr. Mamone] would have not in any way benefited from 

IV t[PA] (or any other recanalization) therapy had it been administered at 

any time from his arrival at St. Clair[.]” Dr. Gebel Supplemental Expert 

Report, 10/23/13, at 4. This conclusion, and a detailed review of the expert 
J-A04014-15 

- 11 - 

opinions offered in this case by all parties, indicates that Dr. Gebel’s 

discussion of the six factors only addressed causation and not the standard 

of care. 

As 

[t]he jury found no negligence on the part of [the] defendant, 

[it] never reached the issues of causation or damages. 

Therefore, any error with regard to the testimony on causation 

was harmless and cannot be the basis for a new trial. . . . 

Plaintiffs suggest that the jurors may have decided there was no 

negligence because they thought there was no causation, but 

this is sheer conjecture.

Ford Motor Co., 2014 WL 7243152, *14 (Pa. Super. Dec. 22, 2014) (en

not reach the issue of causation); see also Boyle v. Indep. Lift Truck, 

Inc., 6 A.3d 492, 496 (Pa. 2010) (issue of comparative negligence went to 

causation and since the jury found that the defendant was not negligent any

harmless); Jewelcor Jewelers & Distribs., Inc. v. Corr, 542 A.2d 72, 80

Calumet Realty Co., 614 A.2d 699, 707 (Pa. Super. 1992) (same with 

respect to superseding cause). 

Appellants identify only three parts of Dr. Gebel’s supplemental expert 

report that implicate the standard of care and suggest that Dr. Traynor 

breached a duty owed to Mr. Mamone by failing to administer tPA. These 

topics include (1) the fact that Mr. Mamone experienced a wake-up stroke; 

(2) the inability of St. Clair to provide tPA within 90 minutes; and (3) the 

size of Mr. Mamone’s stroke.4 However, the record confirms that Dr. Gebel’s 

original expert report discussed these three issues. As to the wake-up 

stroke portion of the report, Appellants concede that Defendants’ theory 

throughout the case was that Mr. Mamone suffered from a wake-up stroke. 

See Appellants’ Brief at 12. In his original expert report, Dr. Gebel’s first 

 

4

 These three issues relate to standard of care, and not causation, because 

they impact whether or not Dr. Traynor should have administered tPA within 

the three-hour time frame. If Mr. Mamone suffered a wake-up stroke, he 

was not a candidate for tPA. If St. Clair were not equipped to diagnose a 

stroke and treat with tPA within 90 minutes, Dr. Traynor did not breach the 

standard of care. Finally, if Mr. Mamone had a large stroke he was not a 

candidate for tPA. Therefore, these three issues related to the jury’s 

determination regarding whether Dr. Traynor breached the standard of care. 

On the other hand, the remaining issues Dr. Gebel discussed in his 

supplemental expert report addressed what would have occurred if Dr. 

Traynor had administered tPA to Mr. Mamone within 90 minutes of his arrival 

at St. Clair. Dr. Gebel opined, in his supplemental expert report, that if Mr. 

Mamone had been administered tPA within that 90 minute timeframe it 

would have had little to no impact on Mr. Mamone’s recovery from the 

stroke. Therefore, these other issues went to the issue of causation and not 

to the standard of care, or breach thereof. 
J-A04014-15 

- 13 - 

opinion was that Mr. Mamone suffered from a wake-up stroke. Dr. Gebel 

Expert Report, 9/23/13, at 3. As to the ability of St. Clair to provide tPA 

within 90 minutes, that issue was also discussed in Dr. Gebel’s original 

expert report. Id. at 4. 

Appellants spend a significant portion of their brief arguing that Dr. 

Gebel’s opinion related to the size of Mr. Mamone’s stroke was a new 

addition to Dr. Gebel’s supplemental expert report. Dr. Gebel’s opinion 

regarding the size of Mr. Mamone’s stroke, however, was discussed in Dr. 

Gebel’s original expert report. Specifically, Dr. Gebel noted that, correctly 

calculated, Mr. Mamone had an NIHSS stroke score of 26. Dr. Gebel’s 

Expert Report, 9/23/13, at 2. A large stroke is considered any stroke where 

the patient’s NIHSS stroke score is greater than 20. Dr. Gebel’s opinion 

relating to the size of Mr. Mamone’s stroke was, therefore, within the fair 

scope of his original expert report. Thus, even if the trial court granted 

Appellants’ motion to strike, Dr. Gebel’s testimony on topics relating to 

standard of care identified by Appellants would not have been precluded. 

Accordingly, any error in failing to grant Appellants’ motion in limine and 

strike Dr. Gebel’s supplemental expert report was harmless. 

 In their second issue on appeal, Appellants argue that the trial court 

erred in permitting Dr. Gebel to testify regarding a congenital absence or 

abnormality of Mr. Mamone’s posterior communicating artery. As this Court 

has explained: 
J-A04014-15 

- 14 - 

The admission of expert testimony is within the trial court’s 

sound discretion and we will not disturb that decision without a 

showing of manifest abuse of discretion. An expert’s testimony 

on direct examination is to be limited to the fair scope of the 

expert’s pre-trial report. In applying the fair scope rule, we 

focus on the word fair. Departure from the expert’s report 

becomes a concern if the trial testimony would prevent the 

adversary from preparing a meaningful response, or which would 

mislead the adversary as to the nature of the response. 

Therefore, the opposing party must be prejudiced as a result of 

the testimony going beyond the fair scope of the expert’s report 

before admission of the testimony is considered reversible error. 

We will not find error in the admission of testimony that the 

opposing party had notice of or was not prejudiced by. 

Whitaker v. Frankford Hosp. of Phila., 984 A.2d 512, 522 (Pa. Super. 

2009) (internal quotation marks and citation omitted); see Pa.R.C.P. 

4003.5(c). 

Appellants argue that Dr. Gebel never discussed a congenital absence 

or abnormality of Mr. Mamone’s posterior communicating artery in his 

original expert report nor in his supplemental expert report. We conclude 

that the trial court did not abuse its discretion by permitting Dr. Gebel to 

testify regarding a congenital absence or abnormality of Mr. Mamone’s 

posterior communicating artery because such testimony was within the fair 

scope of his expert reports. 

Appellants’ argument regarding Dr. Gebel’s testimony is flawed for two 

reasons. First, Appellants entire argument is premised on the fact that 

certain terms were not present in Dr. Gebel’s expert reports. For example, 

Appellants argue that, because Dr. Gebel’s expert reports “never mention 

the terms ‘congenital’, ‘anatomy’, ‘anatomical variation’ or ‘abnormality,’” 
J-A04014-15 

- 15 - 

Dr. Gebel’s testimony was outside the fair scope of his expert reports. 

Appellants’ Brief at 41. Our Supreme Court, however, has rejected use of 

this “magic words” approach to determining if an expert’s testimony is within 

the fair scope of his or her expert report. See Mitzelfelt v. Kamrin, 584 

A.2d 888, 894 (Pa. 1990); see also Expressway 95 Bus. Ctr., LP v. 

Bucks Cnty. Bd. of Assessment, 921 A.2d 70, 79 (Pa. Cmwlth. 2007) 

(internal quotation marks and citation omitted) (“An expert’s trial testimony 

that constitutes a reasonable explanation or even an enlargement of the 

expert’s written words may be deemed to fall within the coverage of fair 

scope.”). Instead, our Supreme Court has instructed that we must view Dr. 

Gebel’s testimony in its entirety, along with his expert reports, to determine 

if the testimony was within the fair scope of his expert reports. See 

Mitzelfelt, 584 A.2d at 894; see also Hickman v. Fruehauf Corp., 563 

A.2d 155, 157 (Pa. Super. 1989), appeal denied, 596 A.2d 158 (Pa. 1991). 

Furthermore, Appellants’ argument is premised on the assumption that 

Dr. Gebel could only testify as to opinions set forth in his original expert 

report and not those opinions expressed in his supplemental expert report. 

This, however, is an incorrect interpretation of Rule 4003.5(c). Rule 

4003.5(c) expressly states that an expert witness may testify regarding 

opinions that he or she offered in a supplemental report. In this case, as 

discussed above, the trial court declined to strike Dr. Gebel’s supplemental 

expert report and we have determined that the trial court did not abuse its 
J-A04014-15 

- 16 - 

discretion in so ruling. Therefore, Dr. Gebel was permitted to testify at trial 

regarding opinions included in both his original expert report and his 

supplemental expert report. 

With these principles in mind, we carefully reviewed Dr. Gebel’s 

original expert report and his supplemental expert report. When considered 

as a whole, we conclude that the expert reports fairly encompass his opinion 

expressed at trial that there was a congenital absence or abnormality of Mr. 

Mamone’s posterior communicating artery. Specifically, in his supplemental 

expert report, Dr. Gebel opined there was “angiographic evidence of no or 

minimal left posterior communicating artery.” Dr. Gebel Supplemental 

Expert Report, 10/23/13, at 4. 

Dr. Gebel’s supplemental expert report used the phrase “no or 

minimal” instead of the term “absence or abnormality.” There is no 

substantive difference between this terminology. The word “absence” 

means “the fact of being without something; lack.” Collin’s English 

Dictionary (10th ed. 2012). Dr. Gebel’s supplemental expert report opined 

that there was evidence that there was no, or lack of a, posterior 

communicating artery. Similarly, a posterior communicating artery that is 

normal is not “minimal.” Thus, it is abnormal. See id. (defining abnormal 

as “not normal; deviating from the usual or typical; extraordinary.”). 

Therefore, Dr. Gebel’s trial testimony aligned closely with the opinion 

contained within his supplemental expert report. As such, Dr. Gebel’s trial 
J-A04014-15 

- 17 - 

testimony was within the fair scope of his expert reports and the trial court 

did not abuse its discretion by permitting him to testify regarding a 

congenital absence or abnormality of Mr. Mamone’s posterior communicating 

artery. 

Furthermore, even if the trial court erred by permitting Dr. Gebel’s 

testimony, such error was harmless. Dr. Gebel’s testimony regarding the 

absence or abnormality of Mr. Mamone’s posterior communicating artery 

addressed causation. Specifically, this testimony attempted to prove that 

even if Dr. Traynor administered tPA within 90 minutes of Mr. Mamone’s 

arrival at St. Clair, Mr. Mamone would not have successfully recovered. 

Contrary to Appellants’ assertions, this testimony was not offered to prove 

that Dr. Traynor had breached the standard of care.5 As noted above, when 

a trial court errs by admitting evidence relating to causation and the jury 

determines that the defendants were not negligent, such error is harmless. 

Accordingly, even if the trial court erred by permitting Dr. Gebel’s testimony, 

Appellants would not be entitled to relief on appeal. 

In their third issue, Appellants argue that the trial court erred by 

granting Defendants’ motion in limine regarding the cross-examination of Dr. 

Traynor. The trial court ruled that Appellants could not cross-examine Dr.

 Appellants argue that the fact that Dr. Gebel was qualified as an expert 

regarding standard of care is dispositive. Dr. Gebel, however, was offered 

as an expert in both standard of care and causation. See N.T., 11/4/13, at 

884. Accordingly, his opinions must be examined to determine if they 

addressed standard of care or causation.

Traynor with respect to any authoritative source other than the ASA 

Guidelines. Appellants argue that they intended to cross-examine Dr. 

Traynor regarding other learned treatises, inter alia, The Streetmedic’s 

Handbook, Owen T. Traynor et al (2004). 

We conclude that Appellants waived this issue. “It is axiomatic that 

‘issues not raised in the lower court are waived and cannot be raised for the 

first time on appeal.’” Commonwealth v. Tejada, 107 A.3d 788, 797 (Pa. 

Super. 2015), quoting Pa.R.A.P. 302(a) (internal alteration and other citation 

omitted). In this case, Defendants filed a motion in limine on the eve of trial 

seeking to prohibit Dr. Traynor from being cross-examined with any learned 

treatise or similar document. Appellants did not file a written response. The 

motion in limine was argued in chambers prior to the commencement of 

trial. The trial court asked Appellants’ counsel “Do you have medical 

treatises you’re going ---” N.T., 10/29/13, at 48. Before the trial court could 

finish its question, Appellants’ counsel replied “Yeah. I’m going to ask him 

about the American Heart Association American Stroke Association 

guidelines.” Id. The trial court ruled that such cross-examination was 

proper in this case. See id. at 48-49. Appellants’ counsel did not aver that 

he was planning on using The Streetmedic’s Handbook or any other learned 

treatise to cross-examine Dr. Traynor. Instead, after Appellants’ counsel 

stated he was planning on using the ASA Guidelines, the trial court granted

Defendants’ motion in limine in part and the parties proceeded to the next 

pre-trial matter.6 

“One of the purposes of the waiver rule is to call alleged errors to the 

trial court’s attention, and give the court the opportunity to correct the 

error.” Stein v. Commw., Dep’t of Transp., Bureau of Licensing, 857 

A.2d 719, 724 n.8 (Pa. Cmwlth. 2004) (citation omitted); see also Parker, 

104 A.3d at 29 (citations omitted). In this case, Appellants did not alert the 

trial court of the alleged error and give it an opportunity to correct itself. 

Instead, the trial court believed that it was ruling in Appellants’ favor 

because it granted Appellants everything they requested – permission to 

cross-examine Dr. Traynor using the ASA Guidelines. In their reply brief, 

Appellants concede they did not give the trial court an opportunity to correct 

its alleged error. See Appellants’ Reply Brief at 21 n.23 (conceding the trial 

court believed the parties had reached a stipulation regarding what 

Appellants could use to cross-examine Dr. Traynor). Appellants cannot 

thereafter argue that the trial court’s ruling was erroneous and entitles them 

to a new trial. Accordingly, Appellants have waived their third issue on 

appeal.

 To the extent Appellants argue that this issue was preserved elsewhere in 

the record, that argument is waived. See Pa.R.A.P. 2117(c) (requiring that 

an appellant’s brief include a statement of where an issue was preserved in 

the record); Pa.R.A.P. 2101 (allowing an appellate court to find waiver when 

an appellant fails to comply with the applicable rules of appellate procedure).

In their final issue on appeal, Appellants argue that the trial court 

erred by granting Defendants’ motions to quash notices to attend/notices to 

produce directed to particular employees of UPMC and St. Clair. The notices 

to attend/notices to produce sought evidence relating to the staffing 

agreement between St. Clair and UPMC. We review the trial court’s rulings 

on the motions to quash for an abuse of discretion. 

Appellants argue that they were prejudiced by the trial court’s quashal 

of their notices to attend/notices to produce because they did not have “the 

opportunity to present evidence regarding Dr. Traynor’s obligations under 

the [s]taffing [a]greement[.]” Appellants’ Brief at 52. They also argue that 

they were prohibited “from showing that Dr. Traynor had a separate duty to 

assist [St. Clair] in development of policies and procedures for [St. Clair’s 

emergency department], including an organized protocol for treatment of 

ischemic stroke patients.” Id. at 53-54. As this information was irrelevant 

to the issues at trial, the trial court did not abuse its discretion in granting 

Defendants’ motions to quash. 

Dr. Traynor’s obligations under the staffing agreement were 

immaterial to this case. The complaint in this case only alleged that Dr. 

Traynor breached his duty of due care by failing to administer tPA to Mr. 

Mamone within the three-hour treatment window. See Complaint, 

10/19/09, at 8-9. Appellants’ complaint did not allege that Dr. Traynor was 

negligent in developing practices and procedures for St. Clair’s treatment of

stroke patients. See id. Dr. Traynor’s obligations and duties under the 

staffing agreement were therefore immaterial to determining whether he 

breached the standard of care with respect to Mr. Mamone’s treatment. 

Furthermore, Appellants did not assert a separate claim against St. Clair 

and/or UPMC for having inadequate practices and procedures in place for the 

treatment of stroke patients. See id. Instead, the complaint only alleged 

that St. Clair and UPMC were vicariously liable for the actions of Dr. Traynor. 

See id. Accordingly, the information sought by the notices to attend/notices 

to produce was not relevant to this case. The trial court therefore acted 

within its discretion by granting Defendants’ motions to quash. 

In sum, we conclude that the trial court did not abuse its discretion by 

declining to strike Dr. Gebel’s supplemental expert report. Dr. Gebel’s 

testimony at trial was within the fair scope of his original and/or 

supplemental expert reports. Furthermore, any error in declining to strike 

Dr. Gebel’s supplemental expert report and/or permitting his trial testimony 

was harmless. Appellants have waived their challenge to the trial court’s 

restriction on materials that could be used to cross-examine Dr. Traynor. 

Finally, the trial court did not abuse its discretion in granting Defendants’ 

motions to quash. 

Judgment affirmed.
