BACKGROUND Saphenous vein harvested with a traditional longitudinal technique often results in leg wound complications. An alternative endoscopic harvest technique may decrease these complications. METHODS One hundred twelve patients scheduled for elective coronary artery bypass grafting were prospectively randomized to have vein harvested using either an(More)
Human cardiac ventricular myosins were prepared from autopsy samples from nine adults, seven infants, and from surgical specimens from seven patients undergoing left ventricular septal myectomy for obstructive hypertrophic cardiomyopathy. Infant myosin differed from adult myosin in two important characteristics: (a) approximately 30% of the 27,000-dalton(More)
To evaluate the role of selective intra-arterial low-dose thrombolytic therapy (SILDT) as an alternative to the surgical management of acute arterial occlusion, the hospital records of 40 patients who underwent 43 SILDT treatments with either streptokinase (36) or urokinase (7) between December 1979 and March 1984 were reviewed. Twenty-eight patients(More)
BACKGROUND Endoscopic harvesting of the greater saphenous vein is increasingly used during cardiac surgery to improve patient satisfaction and reduce the wound complications associated with traditional open techniques. Although histologic studies suggest no significant difference in vein quality between these two techniques, long-term follow-up is lacking(More)
BACKGROUND Vein trauma after saphenectomy by endoscopic or longitudinal techniques may influence the progression of medial and intimal hyperplasia and ultimately affect graft patency. This study compared the histologic characteristics of saphenous veins after endoscopic and longitudinal harvest. METHODS One hundred seventy patients who underwent elective(More)
BACKGROUND Risk factors for leg wound complications following traditional saphenectomy have included: obesity, diabetes, female gender, anemia, age, and peripheral vascular disease. Use of an endoscopic saphenectomy technique may modify the risk factor profile associated with a traditional longitudinal incision. METHODS From September 1996 to May 1999,(More)
BACKGROUND Previous studies in small groups of predominantly nongeriatric patients showed that complex ventricular arrhythmias occurring after coronary artery graft (CABG) surgery are of no prognostic significance. The purpose of this study was to compare the prognosis of patients with and without advanced grade ventricular arrhythmias (AGVA) after CABG in(More)
INTRODUCTION We evaluated the incidence and energy dependence of atrial fibrillation/flutter (AF) induced by implantable ventricular defibrillator shocks in 63 patients tested in the operating room or electrophysiology laboratory. METHODS AND RESULTS Defibrillator shocks were epicardial monophasic in 32 patients, and through an Endotak lead endocardial(More)
Nonpharmacologic treatment using surgery or intracardiac catheter ablation can be used for several forms of supraventricular tachycardia. Surgery is highly successful in preventing recurrent tachyarrhythmias in patients with the Wolff-Parkinson-White syndrome and can be recommended as first-line treatment in several situations. Catheter ablation of the(More)
