BACKGROUND Because the elderly are increasingly referred for operation, we reviewed results with cardiac surgical patients 80 years old or older. METHODS Records of 600 consecutive patients 80 years old or older having cardiac operations between 1985 and 1995 were reviewed. Follow-up was 99% complete. RESULTS Two hundred ninety-two patients had coronary(More)
a S ince the initial publication of ''Guidelines for Reporting Morbidity and Mortality After Cardiac Valvular Operations'' in 1988, 1 followed by a revised version in 1996, 2 valvular heart surgery has evolved to include an enhanced understanding of patient-and disease-related factors affecting outcomes, increased numbers of valve repairs, more operations(More)
Mechanical cardiac valvular prostheses continue to be more popular than bioprostheses for heart valve replacement operations. Five different brands of mechanical heart valves are now approved for implantation in the United States: Starr-Edwards models 1260 and 6120, Medtronic-Hall, St. Jude Medical, Omniscience, and CarboMedics. Each model of mechanical(More)
Between January 1985 and June 1992, 263 consecutive patients had mitral valve reconstruction (133 patients) or replacement (130 patients) for degenerative or ischemic mitral regurgitation. The two groups were similar in sex, age, prior infarctions or cardiac operations, hypertension, angina, and functional class. Both groups were similar in mean ejection(More)
Intracoronary streptokinase was given to 40 patients with acute transmural myocardial infarction. In 34 of the patients (85%), it resulted in reflow or improved flow. Six patients showed no reflow and six reocclusion within 2 hours. No consistent explanation was found for this resistance to therapy. Five other patients developed reocclusion after 6 days to(More)
PTCA was performed in 28 patients with acute MI immediately after intracoronary streptokinase administration. Indications were failure to obtain reflow in 16 patients and high-grade residual stenosis in 12. PTCA was successful in 11 of 16 cases of streptokinase failure, increasing the overall reflow rate from 66% to 77%. PTCA reduced residual coronary(More)
One hundred five patients underwent mitral valve replacement for relief of isolated mitral regurgitation between 1974 and 1979. There were 4 in-hospital deaths (4 percent) and 12 late deaths giving an 82 percent predicted 5 year survival rate. An age of 60 years or more at the time of surgery and a preoperative left ventricular ejection fraction of less(More)
Energy loss is a well-established engineering concept that when applied to evaluating the performance of native heart valves and valvular prostheses has the potential for providing valuable information about the impact of valve function on myocardial performance. The concept has been understood for many years, but its routine application has been hindered(More)
BACKGROUND Appropriate patient selection for surgical repair of the mitral valve depends on the specific location and mechanism of regurgitation, which, in turn, has necessitated a more detailed method to accurately describe mitral pathology. This study tests a strategy of using multiplane transesophageal echocardiography to systematically localize mitral(More)
