BACKGROUND Early implantation of centrifugal devices in patients with postcardiotomy cardiogenic shock may provide a bridge to recovery and allow subsequent long-term survival. METHODS Since January 1989, 62 patients were supported with centrifugal pumps because of failure to wean from cardiopulmonary bypass. Indications were postcardiotomy cardiogenic(More)
Leiomyosarcoma metastatic to the heart is rare and is usually fatal. The authors present the case of a 58-year-old woman who had a history of uterine leiomyosarcoma. Echocardiography and cardiac catheterization revealed a large right ventricular mass. Computed tomography confirmed the presence of the mass which extended into the pulmonary artery. The(More)
BACKGROUND Management of postcardiotomy cardiogenic shock with a ventricular assist device (VAD) is a common and accepted therapeutic option. However, VAD use in patients with mechanical heart valves (MHVs) is thought to carry an increased risk of thromboembolus. We report a series of 7 patients with combined VAD-MHV and review the literature. METHODS A(More)
Cold potassium cardioplegia provides adequate protection for coronary bypass operations, but severe coronary stenoses limit cardioplegic delivery to ischemic regions. The traditional technique delivers cardioplegic solution into the aortic root during the performance of distal anastomoses. The proposed alternative technique constructs proximal as well as(More)
Business-format franchising, which includes the product or service, the brand name or trademark, and the operating system developed by a franchisor, has experienced significant growth over the past few decades. International franchising also is growing at a rapid pace, in part, because of market opportunities that include new trade agreements. The debate(More)
To resolve entry and growth problems, entrepreneurs use creative solutions or tricks, which some may find to be ethically questionable. Generating mistrust is a negative consequence when engaging in entrepreneurial tricks. In spite of that, 66% of entrepreneurs (out of 201 respondents) and 76% of business students (out of 213) consider using some tricks as(More)
The Biomedicus centrifugal pump was required to provide prolonged ventricular support to 13 patients with hemodynamic instability: 11 after cardiovascular surgical procedures, 1 after myocardial infarction and 1 after failure of a heart transplant. The duration of support ranged from 3.5 hours to 9 days (mean 72 hours). Complications included bleeding in(More)
We report the case of a 29-year-old man who suffered sub-arachnoid bleeding while stabilized on a biventricular assist device as a bridge to cardiac transplantation. We adjusted his anti-coagulation therapy to control the bleeding and to concurrently minimize thrombosis while on support. He underwent 2 craniotomy operations to evacuate sub-arachnoid(More)
From 1972 to 1979, 142 aortofemoral bypass grafts were carried out with 5 failures. In 3 of the cases the etiological factor appeared to be hypoplasia of the vessels. After reviewing the charts and arteriograms of the other patients, a further 9 cases in the hypoplastic category were collected. The mean age of the patients was 57 years, all were smokers and(More)
Severe coronary stenoses limit delivery of cardioplegic solution to ischemic regions in patients undergoing bypass operations. A prospective randomized trial was undertaken to determine whether the construction of proximal as well as distal anastomoses during a prolonged cross-clamp period would provide more uniform cardiac cooling and better myocardial(More)
