The automatic implantable cardioverter-defibrillator was implanted in 270 patients because of life-threatening arrhythmias over a 7 year period. There was a history of sustained ventricular tachycardia or fibrillation, or both, in 96% of these patients, 80% had one or more prior cardiac arrests and 78% had coronary artery disease as their underlying(More)
The standard implantable defibrillator waveform is a truncated exponential of approximately 6 msec duration. This study compares the defibrillation efficacy of a standard monophasic truncated exponential to a biphasic 12 msec truncated exponential waveform in 21 patients undergoing automatic implantable cardioverter defibrillator (AICD) surgery. For the(More)
OBJECTIVE Evaluate the operative results of mitral valve repair (MVV) and mitral valve replacement (MVR) performed through standard and smaller incisions. METHODS From January 1997 through December 2002, 821 consecutive patients underwent mitral valve operation. Of these procedures, 475 were MVV and 346 were MVR. A logistic regression model was developed(More)
We reviewed our experience with 43 consecutive patients who underwent operations for postinfarction ventricular septal defect to determine optimal time for operative intervention, to identify factors responsible for failure of operative treatment, and to determine long-term survival rates. Patients were referred for operation after expectant medical(More)
A 17-year-old girl presented with an enlarged cardiac silhouette on routine chest roentgenogram. After clinical evaluation, echocardiography, and pericardiocentesis failed to provide a diagnosis, exploratory thoracotomy and biopsy revealed an unresectable left ventricular fibroma. The tumor continued to enlarge and began causing ventricular arrhythmia.(More)
BACKGROUND We routinely use aortic root enlargement (ARE) as part of one strategy to avoid prosthesis-patient mismatch in patients with relatively small aortic roots who are undergoing aortic valve replacement (AVR). METHODS We performed a retrospective review of 657 consecutive stented AVR patients at a single institution between 1995 to 2001. Of these,(More)
Six patients received heart-lung transplants between March, 1981, and January, 1982. There were four women and two men between 26 and 45 years of age, three with primary pulmonary hypertension and three with congenital heart disease and pulmonary hypertension (Eisenmenger's syndrome). Immunosuppression was primarily with cyclosporin-A, with additional(More)
The currently available automatic implantable cardioverter-defibrillator has proven highly successful for termination of ventricular tachycardia and fibrillation. Newer devices, however, permit lower energy shocks to be delivered initially and longer episodes of arrhythmia to occur before shocks are delivered. These changes may result in longer durations of(More)
In 15 patients undergoing left ventriculomyotomy and myectomy for idiopathic hypertrophic subaortic stenosis (IHSS), the thickness of the interventricular septum was measured before and after muscle resection by means of a modified sternal-notch pediatric ultrasound transducer. Preoperative and intraoperative measurements by echogram were highly correlated(More)
OBJECTIVE Explore causes and timing of death from the CoreValve US Pivotal High-Risk Trial. METHODS An independent clinical events committee adjudicated causes of death, followed by post hoc hierarchical classification. Baseline characteristics, early outcomes, and causes of death were evaluated for 3 time periods (selected based on threshold of surgical(More)
