From 1975 through 1993, 178 patients underwent surgical management of hypertrophic obstructive cardiomyopathy. Operations included isolated septal myectomy (n = 95), septal myectomy and coronary artery bypass grafting (n = 41), septal myectomy plus a valve procedure (n = 25), septal myectomy, valve procedure, and coronary artery bypass grafting (n = 14),(More)
The majority of maturing T lymphocytes that recognize self-antigens is eliminated in the thymus upon exposure to their target antigens. This physiological process of negative selection requires that tissue-specific antigens be expressed by thymic cells, a phenomenon that has been well studied in experimental animals. Here, we have examined the expression in(More)
Reperfusion injury in the surgical setting is defined as those metabolic, functional and structural consequences of restoring coronary flow (that is, aortic unclamping and revascularization) that can be avoided or reversed by modification of the conditions of reperfusion by the operating surgeon. The potential for reperfusion damage exists during cardiac(More)
Twenty-eight consecutive patients underwent aortic valvuloplasty for aortic insufficiency caused by leaflet prolapse. The technique involved triangular resection of the free edge of the prolapsing leaflet, annular plication at the commissure, and resection of a raphe when present in bicuspid valves. Mean age of the patients was 46.8 +/- 14.4 years.(More)
Epiphrenic diverticula occur in association with motor disorders of the distal esophagus, including achalasia and diffuse esophageal spasm. Four patients with huge symptomatic epiphrenic diverticula are presented to emphasize the need for complete radiographic and manometric studies of the esophagus to document this motor dysfunction prior to performing(More)
A technique for the repair of bicuspid aortic valves that includes resection of the flail segment of the prolapsing leaflet, annuloplasty, and resection of the raphe, when present, has been reported. To assess the efficacy of this technique in the repair of insufficient bicuspid aortic valves, the results in 72 consecutive patients were assessed. The mean(More)
BACKGROUND The development of myocardial protective strategies depends on a complete understanding of the pathophysiology of myocardial ischemia and reperfusion. This article reviews the rationale for inclusion of metabolic substrates in cardioplegic solutions on the basis of our current understanding of the underlying pathophysiologic pathways and(More)
This retrospective analysis tests the hypothesis that topical cardiac hypothermia is an unnecessary adjunct to intraoperative myocardial protection and an avoidable cause of pulmonary morbidity in patients with coronary disease receiving blood cardioplegia. The hospital records of 150 nonrandomized consecutive patients undergoing elective and emergency(More)
OBJECTIVES The purpose of this study was to determine the role of intraoperative echocardiography in planning the site and extent of myectomy and in ensuring adequate control of the left ventricular outflow tract gradient. BACKGROUND Although intraoperative echocardiography has been found to be beneficial in patients undergoing valve repair, its impact on(More)
