Published: March 2007

AbstractA case of traumatic arteriovenous fistula and false aneurysm of the internal mammary artery was encountered following sternal wire insertion during cardiac surgery. The diagnosis was suspected by echodoppler and confirmed by arteriography allowing percutaneous embolization using cyanoacrylate in the same setting. © 1993 Wiley‐Liss, Inc.
Directional coronary atherectomy in a distal right coronary lesion using a shorter standard guide catheter
Authors: Ayres Mike 
Published: March 2007

AbstractAn ulcerated and eccentric distal right coronary artery plaque was found in a 56‐year‐old male with post‐infarction angina. The 100 cm length of present DVI (Devices for Vascular Intervention, Inc., Redwood City, CA) atherectomy guiding catheters limits the ability to reach many complex distal stenoses with the 125 cm Simpson Atherocath. After shortening the proximal portion of a standard DVI Judkins right guiding catheter without changing the distal contour, successful directional coronary atherectomy was performed. © 1993 Wiley‐Liss, Inc.
Safety of cardiac catheterization via peripheral vascular grafts
Authors: Lesnefsky Edward J. , Carrea Frank P. , Groves Bertron M. 
Published: March 2007

AbstractThere are few data concerning the complications and technical difficulties encountered when cardiac catheterization is performed using peripheral bypass grafts for vascular access. All cardiac catheterizations performed at our institution from January 1, 1984 to April 1, 1991 were retrospectively reviewed to assess the in‐hospital clinical outcomes in patients who had arterial access for catheterization achieved via prosthetic graft puncture. Seventeen procedures had percutaneous puncture of a vascular graft from a total of 2,929 arterial catheterizations performed. The interval from graft placement to catheterization was 7.5 ± 1.1 years. Arterial sheaths were employed in all cases and corresponded to the catheter size, with 5F systems used in 53% and 7F or larger systems used in the remaining patients. No intraprocedural or postprocedural complications were recognized. Technical difficulties were limited to the inability to selectively cannulate a nondominant right coronary artery in 1 patient. We conclude that percutaneous introduction of an arterial sheath and left heart catheterization via remotely implanted vascular bypass grafts is not associated with an increased risk of procedural complications or technical difficulties. © 1993 Wiley‐Liss, Inc.
Assessment of thallium scintigraphy and echocardiography during dobutamine infusion for the detection of coronary artery disease
Authors: Warner Mark F. , Pippin John J. , Disciascio Germano , Paulsen Walter H. J. , Arrowood James A. , Tatum James L. , Goudreau Evelyne , Vetrovec George W. 
Published: March 2007

AbstractDobutamine infusion was performed in 16 patients following cardiac catheterization, and non‐invasive assessment was performed with thallium SPECT and echocardiography. Dobutamine thallium scintigraphy was abnormal in 93% of patients with significant coronary artery disease. In addition, individual epicardial vessel involvement was identified by a corresponding perfusion defect with 88% sensitivity and 93% specificity. Dobutamine echocardiography revealed segmental wall motion abnormalities in 62% of patients with significant coronary disease. However, in six patients baseline segmental wall motion abnormalities on echocardiography improved during dobutamine infusion. Dobutamine thallium SPECT is a safe and useful test for the detection and localization of coronary artery disease. Dobutamine echocardiography is less useful in screening for coronary disease, but may detect areas of abnormally functioning myocardium having retained viability. © 1993 Wiley‐Liss, Inc.
The use of a new wire in a 6‐year‐old coronary artery occlusion: The Jagwire ™ recanalization guidewire
Authors: Heuser Richard R. 
Published: March 2007

AbstractChronic total occlusions are difficult to treat, usually because they cannot be crossed with a guidewire or dilating catheter. A variety of angioplasty systems designed to facilitate coronary angioplasty of chronic total occlusions have been used. We report the case of a 6‐year‐old occlusion of the right coronary artery that was treated with the Jagwire, a new guidewire designed for use in challenging lesions. This device successfully crossed the lesion and resulted in a successful angioplasty. The patient's angina dramatically improved following the procedure. © 1993 Wiley‐Liss, Inc.
Stenting of a renal artery stenosis achieves better relief of the obstructive lesion than balloon angioplasty
Authors: Dorros Gerald , Prince Charles , Mathiak Lynne 
Published: March 2007

AbstractA balloon‐expandable (Palmaz‐Schatz™) stainless steel stent was utilized following balloon angioplasty (PTRA) to determine if the obstructive lesion, using quantitative methods (automated measuring the diameter stenosis, and transstenotic peak systolic and mean pressure gradients), was significantly further reduced or abolished. Hemodynamic transstenotic gradient and stenoses measurements were made during 21 renal artery stenting procedures; prior and following PTRA, and subsequent to stent deployment. The stent sizes placed in the renal arteries were 5 mm (19%), 6 mm (67%), and 7 mm (14%). The results were as follows:magnified imageThe balloon‐expandable (Palmaz‐Schatz™) stent significantly further reduced, and in fact effectively abolished, the obstructive renal artery lesion in comparison to balloon angioplasty (PTRA). The stent's effectiveness with regard lesion recurrence, maintenance, and preservation of renal function; cure or improved management of hypertension; and survival will be determined by careful clinic follow‐up. © 1993 Wiley‐Liss, Inc.
Inflated balloon entrapped in a calcified coronary stenosis
Authors: Breisblatt Warren M. 
Published: March 2007

AbstractBalloon angioplasty in calcified coronary lesions may have a decreased success rate and an increased incidence of complications. Previous cases have been reported on the phenomena of catheter or wire entrapment, but this report highlights a new problem in association with a calcified stenoses. This case lead to the unusual problem of the inflated balloon being entrapped within the lesion while the distal portion of the balloon remained inflated even after balloon deflation. © 1993 Wiley‐Liss, Inc.

Internal balloon tamponade: A non‐surgical method for removal of accidentally placed sheaths from the subclavian artery
Authors: van Dijk René B. , Heijer Peter Den , Muinck Ebo De , Lie K. I. 
Published: March 2007

AbstractOne of the possible complications of subclavian vein puncture is accidental puncture of the subclavian artery. If this is not noted immediately after the puncture, insertion of a large bore sheath in the subclavian artery is likely to follow. We describe our experience with a new method that enables successful and safe removal of such sheaths without notable blood loss, in three patients. © 1993 Wiley‐Liss, Inc.
Application of intracoronary flow velocity for detection and management of ostial saphenous vein graft lesions
Authors: Kern Morton J. , Flynn Michael S. , Aguirre Frank V. , Donohue Thomas J. , Bach Richard G. , Caracciolo Eugene A. 
Published: March 2007

AbstractOstial lesions of saphenous vein grafts can be difficult to assess by angiography. A physiologic approach to the selection and recanalization of ostial lesions in saphenous vein grafts may be advantageous to overcome limitations of angiography. To assist in identifying favorable physiology and facilitate procedural decision making, the use of coronary flow velocity measurements with a Doppler‐tipped 0.018‐inch angioplasty flowire in three particularly difficult patients with varying types of saphenous vein graft aorto‐ostial narrowings is reported.© 1993 Wiiey‐Liss, Inc.
Holmium:Yag laser‐assisted coronary angioplasty with multifiber delivery catheters
Authors: White Christopher J. , Ramee Stephen R. , Collins Tyrone J. , Mesa Juan E. , Murgo Joseph P. 
Published: March 2007

AbstractMid‐infrared lasers are attractive for coronary angioplasty based upon their excellent fiberoptic transmission and enhanced tissue absorption. Using a solid‐state, mid‐infrared holmium:YAG laser with prototype multifiber laser delivery catheters, we performed coronary laser angioplasty with or without adjunctive balloon angioplasty or directional atherectomy in 14 patients with 17 stenoses. Procedural laser success was obtained in 13/14 (93%) patients and 16/17 (94%) lesions; however clinical success was achieved in 9/14 (64%) patients and 12/17 (71%) stenoses. Angiographic restenosis at 4.6 ± 1.6 months was found in 5/8 (63%) patients. We achieved an excellent procedural laser success rate in patients with generally unfavorable angioplasty anatomy. However, our clinical success rate was not different from that expected with conventional angioplasty alone. The holmium laser remains an attractive energy source for laser angioplasty; but as is the case for all coronary laser systems, its utility as a stand‐alone therapy is limited by catheters which create small channels. In this small group, we could demonstrate no clinical benefit for laser‐assisted angioplasty in complex coronary lesions. Our results suggest that a randomized trial comparing laser‐assisted angioplasty and conventional angioplasty be performed to determine the clinical benefits of this more expensive therapy.© 1992 Wlley‐Liss, Inc

Optimizing surgical backup for multiple simultaneous percutaneous transluminal coronary angioplasty procedures
Authors: AvendañO Amilcar , Vaughn William , Reece Barbara , Ferguson James J. 
Published: March 2007

AbstractAt busy interventional centers, it may be difficult to coordinate surgical backup for multiple simultaneous PTCA procedures. We sought to determine the actual risk of two simultaneous cases requiring surgery, and to identify a group in which multiple simultaneous PTCA procedures could be performed at low risk.We prospectively applied the ACC/AHA A/B/C lesion classification system and an empiric low/medium/high risk classification (based on patients' overall clinical picture) to 1,128 PTCA procedures over a 9 month period; 22 of these patients (1.9%) went directly from the catheterization laboratory to emergency CABG. The incidence of emergency CABG by groups was A‐low 1/166, A‐medium 1/71, A‐high 0/22, B‐low 1/116, B‐medium 10/481, B‐high 2/52, C‐low 2/47, C‐medium 3/88, and C‐high 2/85.The patients were divided into two groups: minimal risk (A + B‐low: 3/375 or 0.8%) and increased risk (B‐med/high + C: 19/753 or 2.5%). The difference between the groups was significant using chi square with an α < 0.05. The risk of two cases requiring surgery at the same time was calculated as a function of the number of simultaneous PTCA procedures performed. Six or fewer minimal risk PTCA, one increased risk plus up to three minimal risk, and a maximum of two increased risk cases were found to have a risk of <0.001.We conclude that it is possible to identify a group of patients with minimal risk, in whom multiple simultaneous procedures can be performed with a negligible probability of two cases requiring surgery at the same time.Single surgical backup for multiple simultaneous increased risk cases is associated with a finite degree of risk. Some form of risk assessment should be incorporated into institutional algorithms for allocating surgical backup in the setting of multiple simultaneous PTCA procedures.

Technique for shortening angioplasty guide catheter length when therapeutic catheter fails to reach target stenosis
Authors: Stratienko Alexander A. , Ginsberg Robert , Schatz Richard A. , Teirstein Paul S. 
Published: March 2007

AbstractOccasionally, the usable length of a balloon angioplasty or other therapeutic catheter is insufficient to reach the target stenosis. We describe a technique of shortening the guide catheter from the proximal end in vivo without removing the coronary guidewire. This permits greater projection of the therapeutic catheter to reach distal stenoses.© 1993 Wlley‐Liss, Inc
Directional atherectomy with the omnicath™: A unique new catheter system
Authors: Mazur Wojciech , Ali Nadir M. , Rodgers George P. , Schulz Daryl G. , French Brent A. , Raizner Albert E. 
Published: March 2007

AbstractOmnicath™ is a directional atherectomy catheter that employs deflecting nontraumatizing wires to anchor the cutting window at the atherectomy site. This anchoring system regulates the depth of cut and provides directional control and distal perfusion. The system continuously removes debris through a suction port from the operative site. To demonstrate the performance of the device, the Omnicath™ was tested in the external iliac arteries of ten atherosclerotic Hanford miniature swine in which concentric and eccentric lesions were induced. Five animals were sacrificed 3 days after atherectomy; the remaining five animals were sacrificed 6 weeks after the procedure. The acute histology demonstrates depth of cuts varying from partial plaque removal to near full thickness removal of the arterial wall. Histologic sections of the 6 week follow‐up group demonstrated minimal healing response. The anchoring wires did not induce either acute injury or neointimal proliferation in the 6 week follow‐up period. In conclusion, the Omnicath™ permits effective and safe atherectomy in this investigative model.

AbstractThe early and late effects of a new balloon‐expandable coronary stent (Boneau II) were studied in 16 adult mongrel dogs. Thirty‐three balloon‐expandable stents were deployed using standard transfemoral coronary angioplasty technique. Single stents were placed in eight dogs and multiple (two to four) stents were placed in eight dogs. Intravenous heparin (3,000 units) was administered at the beginning of the procedure. Aspirin, dipyridamole, dextran, and warfarin were not administered before or after the procedure. All stent deployments were successful. Angiographic or pathologic examinations were performed within 24 hr of deployment on two of the dogs, at 2 weeks on two of the dogs, at 2 months on three of the dogs, at 6 months on six of the dogs, and at 1 year on three of the dogs. All successfully deployed stents were noted to be widely patent. There was no evidence of side‐branch vessel occlusion. There was no evidence of acute or late vessel thrombosis. Histologic examination at 2 months showed a mean intimal thickness of 153 μm.The stainless steel Boneau II coronary stent is relatively short and easily deployed. This balloon‐expandable coronary stent was successfully deployed in normal canine arteries without the use of anticoagulation or antiplatelet therapy before or after the procedure. The Boneau II intracoronary stent has a very low thrombogenic potential in dogs.
Lupus anticoagulant: A potential risk factor for complication following percutaneous transluminal coronary angioplasty
Authors: Anglin Peter , Strauss Bradley H. , Brandwein J. M. , Watson K. Randall 
Published: March 2007

AbstractA patient is described with antiphospholipid antibodies who died approximately 24 hr after an uncomplicated balloon angioplasty. Since the literature suggests a relationship between the presence of antiphospholipid antibodies and thromboses, we suggest that these antibodies may be a risk factor for abrupt closure after percutaneous transluminal coronary angioplasty.
Spontaneous arterial embolization after thrombolytic therapy for acute myocardial infarction: The role of transesophageal echocardiography

Published: March 2007

AbstractArterial embolization from thrombolytic therapy for acute myocardial infarction is rare. We report two cases of spontaneous arterial embolization following the use of tissue plasminogen activator for acute myocardial infarction. Transesophageal echocardiography was able to identify the source of embolism as mobile atherosclerotic debris within the thoracic aorta. This information was of value in the management of these patients, in that femoral catheterization which could have precipitated further embolization was avoided.

Published: March 2007

AbstractPercutaneous transluminal coronary balloon angioplasty (PTCA) has had limited success with higher complication and restenosis rates in aorto‐ostial lesions. Directional coronary atherectomy (DCA) has been advocated as an alternative to PTCA in such lesions. In this report, we describe a potential complication of DCA in right coronary ostial lesions.

Published: March 2007

AbstractLocal intramural delivery of various pharmacologic agents following angioplasty has been proposed as a means of reducing restenosis. This study tested whether local intramural delivery of aqueous solutions using an infusion balloon could be accomplished safely in normal vessels and whether such infusion was safe following standard angioplasty in diseased vessels. Infusion of aqueous agents into normal canine arteries had no adverse effect. Infusion of several aqueous agents (≤4 cc at 4 atm) into diseased swine iliac arteries following balloon angioplasty did not worsen existing or create new dissections. Histologically, infusion treated vessels did not differ in either model from vessels treated with angioplasty alone. We conclude that local intramural drug infusion does not create new, or worsen existing, dissections produced during standard balloon angioplasty in diseased vessels.
