BACKGROUND Insertion of an implantable left ventricular assist device (LVAD) complicated by early right ventricular (RV) failure has a poor prognosis and is largely unpredictable. Prediction of RV failure after LVAD placement would lead to more precise patient selection and optimal device selection. METHODS AND RESULTS We reviewed data from 245 patients(More)
BACKGROUND We investigated whether axillary/subclavian artery inflow with a side graft decreases the risk of stroke versus cannulation at other sites during hypothermic circulatory arrest. METHODS Between January 1993 and May 2003, 1,352 operations with circulatory arrest were performed for complex adult cardiac problems. A single arterial inflow(More)
BACKGROUND Aortic valve replacement in patients with severe atherosclerosis of the ascending aorta poses technical challenges. The purpose of this study was to examine operative strategies and results of aortic valve replacement in patients with a severely atherosclerotic ascending aorta that could not be safely crossclamped. PATIENTS AND METHODS From(More)
BACKGROUND Implantable left ventricular assist devices (LVAD) are used as a bridge to transplantation but are associated with a high risk of infection including nosocomial bloodstream infections (BSI). METHODS We retrospectively reviewed the medical records of all patients with implantable LVAD at the Cleveland Clinic with 72 hours or longer of LVAD(More)
We describe our clinical experience with 205 implantable left ventricular assist devices at the Cleveland Clinic between December 1991 and January 2000, along with manufacturers' data submitted to the Food and Drug Administration. In patients with end-stage cardiac failure who are suitable candidates for transplantation, these devices serve as excellent(More)
BACKGROUND Pericardial valves have excellent hemodynamic function; however, long-term durability is questionable. To determine the function of the Carpentier-Edwards pericardial valve in the aortic position, the results of 310 aortic valve replacements performed between 1982 and 1985 were analyzed. Mean age was 64.2+/-10.8 years (range, 22 to 95 years); 190(More)
OBJECTIVE To determine whether vacuum-assisted venous return has clinical advantages over conventional gravity drainage apart from allowing the use of smaller cannulas and shorter tubing. METHODS A total of 150 valve operations were performed at our institution between February and July 1999 using vacuum-assisted venous return with small venous cannulas(More)
BACKGROUND Bioprosthesis durability decreases with time and younger age. However, the time-scale and determinants of durability of the aortic Carpentier-Edwards stented bovine pericardial prosthesis are incompletely characterized. METHODS Between September 1981 and January 1984, 267 patients underwent implantation of the pericardial aortic prosthesis at(More)
BACKGROUND Orthotopic heart transplantation (OHT) was initially done by the biatrial technique, although the bicaval technique has recently become more popular. The aim of this study was to compare OHT outcomes when using the bicaval technique vs the biatrial technique. METHODS A total of 615 patients were transplanted at the Cleveland Clinic Foundation(More)
Nonspecific investigations resulting in treatment delays contribute to the 30 per cent mortality associated with acute mesenteric ischemia (AMI). As preliminary studies indicate that alpha-glutathione S-transferase (alpha-GST) is elevated in AMI we compare the ability of alpha-GST against conventional biochemical tests to predict AMI. There were 58 patients(More)
