The optimal management of endoleaks after endovascular repair of abdominal aortic aneurysms remains to be established. In this report, we describe a persistent side-branch, or type II, endoleak 1 year after endograft implantation treated with cathete

Heparin reduces ischemia-reperfusion injury to myocardium. This effect has been attributed to complement inhibition, but heparin also has other activities that might diminish ischemia-reperfusion. To further probe these mechanisms, we compared hepari

Nitric oxide is an endogenous autacoid produced primarily by the vascular endothelium. Under basal conditions, nitric oxide undergoes a rapid biradical reaction with superoxide anions to form peroxynitrite. This reaction, and hence the formation of p

The normal coronary vascular endothelium (VE) tonically releases nitric oxide (NO) by converting L-arginine to citrulline by a constitutive NO synthase. Reperfusion after myocardial ischemia reduces basal and stimulated release of NO. This "vascular

Background . In an attempt to avoid the deleterious effects of cardiopulmonary bypass, off-pump coronary artery bypass grafting has been rediscovered and refined. The purpose of this study was to compare clinical outcomes, length of stay, and hospita

In 1967, Christian Barnard performed the first successful human-to-human heart transplant. Following this triumph, the ensuing decade saw a waning interest in heart transplantation given the complications related to rejection and immunosuppression. W

Ischemia-reperfusion results in contractile dysfunction, necrosis, and vascular injury. This postischemic injury is mediated in part by superoxide radical production, neutrophils, dysfunction to ionic pumps, and edema formation. Adenosine is an autac
