Successful rotational coronary ablation following failed balloon angioplasty
Authors: Iyer Sriram S. , Hall Patrick , King James F. , Dorros Gerald
Published: March 2007

Rotational coronary ablation was utilized in two cases in which balloon angioplasty initially failed. In both cases, the balloon could not be fully expanded despite using high (18 Bar) inflation pressure. Rotational coronary ablation debulked the lesion, in each instance, and permitted successful balloon angioplasty to be accomplished without difficulty. These cases illustrate the point that complementary deployment of devices may not only improve the primary success of percutaneous coronary interventions, but also may widen its scope.
Cardiac catheterization 1990: A report of the registry of the society for cardiac angiography and interventions (SCA&I)
Authors: Noto Thomas J. , Johnson Lewis W. , Krone Ronald , Weaver Walt F. , Clark David A. , Kramer John R. , Vetrovec George W. , Parker Justine J.
Published: March 2007

This report presents the first year's experience of a totally computerized cardiac catheterization laboratory reporting system, including the results and complications of invasive and interventional procedures. Sixty‐three laboratories reported a total of 71,916 patients studied between January 1 through December 31,1990. Two previous registry reports have been published. Compared with data acquired by previous methods, in spite of an older and sicker population, the mortality for diagnostic procedures has remained remarkably constant (0.11%). The computerized format facilitates data collection and analysis, helps resolve new issues as they arise and serves as a method of monitoring quality of laboratories and Individuals.
Predictors of early mortality in patients with angiographically documented left main coronary artery disease
Authors: Ko Jae‐Ki , Nishimura Rick A. , Holmes David R. , Bailey Kent R.
Published: March 2007

To determine predictors of early death after coronary angiography In patients with significant left main coronary artery disease (≥ 60% diameter narrowing, LMCAD), we reviewed the clinical records of patients with LMCAD who died after angiography. Of 1,288 patients with LMCAD studied between January 1978 and October 1989, 21 died within 2 days after angiography (group 1). As a control group, 85 patients were randomly sampled from 1,196 patients who survived at least 30 days after angiography (group 2). The predictors of early death after angiography in patients with LMCAD were older age (P < 0.05), New York Heart Association Class III or IV (P < 0.005), shorter duration of unstable angina (P < 0.005), higher left ventricular end‐diastolic pressure (P < 0.006), lower ejection fraction (P < 0.005), and significant left circumflex artery disease (P < 0.006). The use of heparin infusion after angiography did not appear to be a significant factor. It is suggested that earlier operation or more aggressive management be undertaken in patients who, at cardiac catheterization, have significant LMCAD associated with the above‐listed variables.
Two hugging balloons at high pressures successfully dilate a lesion refractory to routine coronary angioplasty
Authors: Feld Harry , Valerio Louise , Shani Jacob
Published: March 2007

A small portion of lesions are refractory to coronary angioplasty even when very high pressures are used. This leads to a failed angioplasty and emergent bypass surgery. We successfully attempted the technique of hugging balloons or two polyethelene terephthalate (PET) balloons inflated simultaneously side by side which successfully dilated a lesion which would not dilate using standard techniques. This technique successfully dilated the lesion as the geometry of two balloons inflated side by side is different from one balloon. Two balloons inflated side by side consists of two outer semi‐circles and a central trapezoidal square area. This altered geometric configuration may be important in successfully dilating a lesion refractory to standard dilating techniques. Higher pressures can be attained with smaller balloons as the burst pressure is higher in smaller balloons compared to larger balloons.
Initial experiences with a miniaturized pressure transducer during coronary angioplasty
Authors: Emanuelsson HÅKan , Dohnal Michal , Lamm Carl , Tenerz Lars
Published: March 2007

A newly constructed pressure sensor with a diameter of 0.45 mm was evaluated in 15 patients undergoing balloon coronary angioplasty (PTCA). The sensor and an optic fiber were mounted on a 0.018″ guide wire, which was used in the balloon catheter.

Pressure gradients were recorded before and after PTCA, respectively. The pressure tracings were of satisfactory quality in all cases. The mean systolic and diastolic gradients before PTCA were 32 ± 20mm Hg and 44 ± 26mm Hg, respectively. Pressure gradients were also obtained with the balloon placed in the lesion in order to simulate the conventional way of pressure measurement through the balloon catheter. In this setting, the systolic and diastolic gradients were 77 ± 32mm Hg and 59 ± 25mm Hg, respectively. Following balloon dilatation, the systolic pressure gradient decreased to 14 ± 12mm Hg, and the diastolic gradient to 13 ± 11 mm Hg. In conclusion, this new pressure sensor delivers recordings of good quality and may be especially of interest during angioplasty due to its small diameter.
Performance characteristics of a new shape of guiding catheter for ptca of the left coronary artery
Authors: Nesto Richard W.
Published: March 2007

The inability to successfully perform angioplasty commonly involves inadequate guiding catheter performance. We evaluated the use of a new left coronary guiding catheter for angioplasty (PTCA) of lesions in both the left anterior descending and left circumflex arteries. The Nesto™ guide in two different sizes was used in 100 consecutive PTCA cases as a primary catheter. The catheter successfully cannulated the left main coronary artery in 93 patients and PTCA was successfully performed in 85 patients for target lesions at various locations in either or both vessels. Positive features of this new guiding catheter include superior back‐up support and ease of disengagement.
Effects of atrial septostomy in patients with terminal cor pulmonale due to pulmonary vascular disease
Authors: Nihill Michael R. , O'Laughlin Martin P. , Mullins Charles E.
Published: March 2007

Fourteen patients with pulmonary vascular disease, either primary pulmonary hypertension or the result of cardiac defects, underwent balloon atrial septostomy (BAS) over the period of July 1981 to June 1988 because of symptoms of syncope, fatigue, right heart failure, and cardiac arrest. Ages ranged from 4 mo to 50 yr. Two moribund patients died within 24 h of the septostomy due to severe hypoxemia and unrelieved low cardiac output; three others died 2 wk to 35 mo later; the remaining 9 patients have improved symptomatically and are alive 11 to 96 mo after septostomy. One received a heart and lung transplant 19 mo later. We conclude that, in patients with symptomatic cor pulmonale secondary to pulmonary vascular disease, atrial septostomy can improve symptoms and may serve as a palliative bridge to heart and/or lung transplantation.

Authors: Yeoh Joon‐Kuan , Choo Hock‐Heng , Soo Chee‐Siong , Lim Yean‐Teng , Yan Chee‐Hong
Published: March 2007

A case of spontaneous coronary artery dissection in a young male with subsequent myocardial infarction is reported. In addition, distal vessel occlusion is noted, presumably from embolization of thrombotic material originating from the site of dissection. Postulated mechanisms of this uncommon cause of myocardial infarction and subsequent therapeutic options are reviewed.

A patient with right bundle branch block and left anterior fascicular block developed complete heart block during passage of a catheter into the left ventricle. Intracardiac electrograms showed the block to be in the distal His‐Purkinje system. The block resolved without complications.
Brachial approach directional coronary atherectomy of right coronary artery saphenous vein bypass grafts
Authors: Lindsey Richard L. , Kleist Paul C.
Published: March 2007

We describe here a technique for performing directional coronary atherectomy to right coronary artery saphenous vein bypass grafts from the brachial approach using a long introducer sheath system. This technique has the advantages of (1) avoiding femoral artery trauma and (2) ease of access into the bypass graft, avoiding occasional problems with guide catheter kinking or non‐coaxial alignment.
A solution to the problem of an unexpanded palmaz‐schatz stent following balloon rupture
Authors: Pitney Mark R. , Cumpston Neil
Published: March 2007

The Palmaz‐Schatz stent is a balloon expandable stent. Although easy to deploy, problems can occur. One problem is balloon rupture resulting in a partially expanded stent, which can be difficult to expand fully. This report illustrates how a Probing catheter and balloon can solve this potentially serious problem.
Disruption of a coronary stent during atherectomy for restenosis
Authors: Bowerman Richard E. , Pinkerton Cass A. , Kirk Beth , Waller Bruce F.
Published: March 2007

Directional coronary atherectomy is being used in the treatment of atherosclerotic lesions in coronary vessels and vein grafts. This report describes the use of atherectomy for the treatment of restenosis of a coronary stent. The procedure was complicated by disruption of the stent which was snared by the atherectomy cutter.
Do stents interfere with the densitometric assessment of a coronary artery lesion?
Authors: Strauss B. H. , Rensing B. J. , Den Boer A. , Van Der Giessen W. J. , Reiber J. H. C. , Serruys P. W.
Published: March 2007

This in vitro study was designed to assess the contribution of three currently investigated coronary stents to the densitometrlc measurement of a known stenosis contained within two different sized plexiglass phantoms. These studies were performed at two concentrations of the contrast agent iopamidol (50 and 100%). The calculated minimal luminal cross‐sectional area values in the control phanton ranged from 0–18% higher than the theoretical values. Insertion of a stainless steel stent (Wallstent™, Schneider, Zürich or Palmaz‐Schatz™, Johnson and Johnson, Warren, NJ) resulted in further minor increases (≤8%) in the calculated minimal luminal cross‐sectional area, except in the smaller phantom filled with 50% contrast medium. The Wiktor™ (tantalum) stent (Medtronic, Minneapolis, MN) had the largest impact of the three stents depending on the concentration of iopamidol (100% contrast medium: 9–13% values above control; 50% contrast medium; 23–56% higher). We conclude that although densitometry may overestimate the minimal luminal cross‐sectional area in stented vessels, this effect is usually minor with stainless steel stents. However, tantalum‐containing stents may result in serious overestimation of lesion area, particularly if contrast is diluted or the vessel Is not well filled.

Published: March 2007

A 58‐year‐old male presented with an anterior mediastinal mass which was found to be secondary to an aneurysmal dilatation of the saphenous vein graft to his circumflex artery. This represents an unusual presentation of an aneurysmally dilated saphenous vein graft.
Variations in blood supply to the anterior interventricular septum: Incidence and possible clinical importance
Authors: Ilia Reuben , Goldfarb Benjamin , Katz Amos , Margulis Giora , Gussarsky Yehoshua , Gueron Moshe
Published: March 2007

The variations of the blood supply to the anterior interventricular septum in a series of 1,089 patients are described. Special attention has been given to variations and frequency of occurrence of the septal perforators originating from the left anterior descending artery. These variations may have clinical significance in this era of coronary angioplasty and coronary bypass surgery.
Percutaneous triple‐valve balloon valvuloplasty in a pregnant woman
Authors: Savas Vicky , Grines Cindy L. , O'Neill William W.
Published: March 2007

A 22‐yr‐old pregnant woman with mitral, aortic, and tricuspid stenosis presented with accelerating dyspnea and shortness of breath at the end of her first trimester. She subsequently underwent percutaneous triple‐valve balloon valvuloplasty at 22 weeks of gestation without complications and achieved marked clinical improvement. We conclude that percutaneous triple‐valve balloon valvuloplasty represents an alternative treatment for mitral, aortic, and tricuspid stenosis in pregnant women with compromised cardiovascular status who do not wish to terminate their pregnancy.
Flow support catheter for prolonged maintenance of coronary blood flow
Authors: Clugston Richard , Oesterle Stephen N. , Matthews Ray , Dawson Richard , Garrison Michi , Alker Kevin , Reeves Tim , Virmani Renu , Kloner Robert A.
Published: March 2007

A newly designed flow support catheter with a supporting wire mesh cage which can be expanded into a tubular configuration and then readily reduced was evaluated in mongrel dogs. Regional myocardial blood flow (RMBF) was measured using the radioactive microsphere technique in the area of both balloon‐denuded instrumented and control non‐instrumented coronary arteries following placement of either a fixed‐wire or a higher profile rapid exchange flow support catheter. At 5, 20, and 180 min following delivery and expansion of either device, RMBF was not significantly different in left ventricular subepicardium and subendocardium perfused by the instrumented vs. the control coronary arteries. Angiography demonstrated widely patent instrumented arteries in 15/18 dogs; in no dog was side branch occlusion observed. Significant cage thrombus deposition was seen angiographically in 3 animals causing temporary total coronary occlusion in 1. Following reduction and removal of the flow support catheter, vessel patency was present in all dogs. The flow support catheter is an effective endovascular stenting device capable of providing structural arterial support, while simultaneously maintaining distal coronary blood flow. It is envisioned that the primary application of this catheter will be to enable primary salvage of vessels acutely injured during coronary angioplasty, by “tacking up” intimal flaps for an extended period. It may also provide a bridge to emergency surgical revascularization.

Published: March 2007

Balloon aortic valvuloplasty (BAV) was performed in 219 elderly patients with aortic stenosis between December 1985 and April 1990. Forty‐three patients underwent repeat BAV for symptomatic restenosis of the aortic valve 13±8 mo following initial BAV. To evaluate the outcome following initial and repeat BAV, hemodynamic results were analyzed according to the following subgroups: BAV 1‐initial BAV for all patients (n = 219); BAV 1/1‐initial BAV in those who had only one BAV (n = 176); BAV 1/2‐the initial BAV in those who had repeat BAV (n = 43); and BAV 2‐repeat BAV (n = 43).

The mean age of patients undergoing BAV 2 was 82±6 yr compared to 78±10 yr for all patients undergoing BAV 1 (p = .01). At the time of BAV 1 there was no difference in baseline or post‐valvuloplasty aortic valve area (AVA) or peak aortic valve gradient (AVG) for patients having BAV 1/1 compared to those having BAV 1/2. However, for patients having repeat BAV, although the magnitude of the hemodynamic improvement of BAV 1/2 (AVA increased from 0.6 to 0.9 cm2, AVG decreased from 65 to 34 mm Hg, p<.001) was similar to the magnitude of the hemodynamic improvement of BAV 2 (AVA increased from 0.5 to 0.8 cm2, AVG decreased from 65 to 34 mm Hg, p<.001), the baseline AVA (0.5 cm2 at BAV 2 vs. 0.6 at BAV 1/2) and the post‐valvuloplasty AVA (0.8 cm2 at BAV 2 vs. 0.9 at BAV 1/2) were significantly smaller (p<.004). There were no major complications in patients undergoing repeat BAV. Median event‐free survival was 12 mo after initial BAV and 8 mo after repeat BAV (p = .09).

In conclusion, repeat BAV results in similar immediate hemodynamic improvement and event‐free survival compared to initial BAV. However, baseline aortic valve area and gradient prior to repeat BAV are significantly worse than those prior to initial BAV, suggesting that balloon‐induced injury to the aortic valve may offer only a temporary hiatus from the natural history of aortic stenosis.
Atresia of the left main coronary artery: Clinical recognition and surgical treatment
Authors: Bedogni Francesco , Castellani Antonio , La Vecchia Luigi , Menicanti Lorenzo , Finocchi Giuseppe , Dor Vincent , Vincenzi Mario
Published: March 2007

Atresia of the left main coronary artery is an extremely rare anomaly with very few cases presented in the literature. Even more uncommon are reports of successful surgical repair. This article concerns two cases of atresia of the left main coronary artery treated surgically with a favourable outcome.

The two patients (a 16 year‐old boy and a 43 year‐old woman) had a different clinical presentation but identical angiographic and morphologic features. The authors examine the embryogenetic defect underlying this anomaly. The differential diagnosis involves two congenital malformations (single coronary artery and anomalous origin of the left coronary artery from the pulmonary trunk) and acquired atherosclerotic disease of the left main coronary artery; the distinguishing features of these conditions are reviewed.

Surgical management by means of internal mammary artery revascularization is discussed in light of recent reports about adequacy of blood flow in internal mammary artery bypass grafts.
Sheath introducer technique for recanalizing total occlusions of the superficial femoral artery
Authors: Bauriedel Gerhard , Demaio Samuel J. , Höfling Berthold
Published: March 2007

Symptomatic patients with total superficial femoral artery occlusions were approached with a modified Dotter technique followed by PTA and/or atherectomy. In 21 lesions studied, 7 (33%) were crossed with a conventional guide wire. Of the remaining 14 lesions (67%), 12/14 (86%) were crossed successfully using the pliable distal tip of the sheath introducer. The average angiographic lesion length crossed was 42 ± 29 mm (range 8–109 mm). One insertion site vessel complication requiring surgical repair was seen. Although more advanced technologies have been developed to treat “wire resistant” total occlusions, the use of the introducer technique described is effective in many patients and adds no additional cost or time to the standard angioplasty procedure.
Internal mammary artery angiography should be a routine component of diagnostic coronary angiography
Authors: Feit Alan , Reddy C. V. , Cowley Carlos , Ibrahim Bassiema , Zisbrod Zvi
Published: March 2007

Left internal mammary artery (LIMA) angiography was performed with diagnostic coronary angiography in 130 cases for which the coronary findings made use of the LIMA as a bypass graft a consideration. In 98% of the cases the approach to LIMA angiography was femoral with a 5F LIMA catheter first directed into the proximal subclavian and then advanced over a guidewire placed into the distal subclavian well beyond the origin of the LIMA. After withdrawing the wire the catheter was brought proximally to selectively can‐nulate and visualize the LIMA with nonionic contrast media. The only complication was a single transient occipital visual field loss.

LIMA caliber too narrow to permit use as a graft was found twice, LIMA occlusion unrelated to prior surgery was found once, and LIMA occlusion related to prior surgery was found twice. Subclavian and/or vertebral stenosis was present five times. Large proximal branches of the LIMA best identified prior to surgery were present 12 times.

Based on this experience, LIMA angiography (1) can be performed safely with a high degree of success, (2) demonstrates significant findings in 15% of cases, and 3) should therefore be performed whenever coronary angiographic findings make it appropriate to consider LIMA to coronary artery bypass grafting.
Inaccuracies in manufacturer‐reported deflated ptca balloon profiles
Authors: Ferguson James J. , Parnis Steven M. , Fuqua John M.
Published: March 2007

Deflated balloon profile is an important consideration in the selection of PTCA catheters. In order to test the accuracy of manufacturer‐reported balloon profiles, we measured deflated shoulder and mid‐balloon profile in 107 unused catheters (2.0, 2.5, and 3.0 mm) from 6 manufacturers using a precision hole gauge with a resolution of .001 inches. A significant difference was defined as a discrepancy ≥0.003 inches from the manufacturer's reported profile.

During Phase I, measurements were obtained at room temperature on catheters directly out of the package. Of the 36 models tested, 21/36 (56%) had measured shoulder profiles that were larger than their reported profile, and 29/36 (81%) had mid‐balloon profiles that were larger than their reported profile.

During Phase II, measurements were made at body temperature following a 60 second inflation at 120 psi (8.16 atm). Of 33 models tested, 18/33 (55%) had measured shoulder profiles that were larger than their reported profile; 26/33 (79%) had mid‐balloon profiles that were larger than their reported profile.

The term “profile” is imprecisely defined. Manufacturer‐reported deflated PTCA balloon profiles are not always accurate. Independent and uniform testing of balloon profiles is necessary for valid comparisons between balloons and manufacturers.
Thrombus causing fatal left ventricular outflow tract obstruction in a heart transplant patient
Authors: Clark Vivian L. , Levine T. Barry
Published: March 2007

A 60 year male, orthotopic heart transplant recipient developed a fatal left ventricular outflow obstruction secondary to thrombus at 38 months post transplant. Although he had episodes of mild to moderate rejection at 2 and 16 months post transplant, subsequent biopsies were negative and annual cardiac catheterizations showed mild left ventricular hypokinesis and normal coronary arteries. This case represents a catastrophic complication of transplant rejection and illustrates the problems with identifying rejection using current diagnostic methods.
Balloon dilation of pulmonary venous pathway obstruction in an infant after the mustard procedure

Published: March 2007

Pulmonary venous pathway obstruction developed after a Mustard procedure in an infant with transposition of the great arteries. The stenosis was successfully dilated by the percutaneous balloon technique with immediate clinical, echocardiographic, and hemo‐dynamic improvement, which has persisted for 8 months after dilation. This technique is a feasible alternative to reoperation in such an obstruction, even in infants.
High‐Throughput Synthesis and Analysis of Acylated Cyanohydrins

Published: March 2007

The yields and optical purities of products obtained from chiral Lewis acid/Lewis base‐catalysed additions of α‐ketonitriles to prochiral aldehydes could be accurately determined by an enzymatic method. The amount of remaining aldehyde was determined after its reduction to an alcohol, whilst the two product enantiomers were analysed after subsequent hydrolysis first by the (S)‐selective Candida antarctica lipase B and then by the unselective pig liver esterase. The method could be used for analysis of products obtained from a number of aromatic aldehydes and aliphatic ketonitriles. Microreactor technology was successfully combined with high‐throughput analysis for efficient catalyst optimization.
