We report the case of an 85-year-old woman with severe aortic stenosis who underwent transcatheter aortic valve replacement with use of the Edwards Sapien(®) valve system. The procedure was complicated by rupture of the valve-deployment balloon, with separation and retention of the nose cone of the RetroFlex 3(®) delivery system in the iliac artery. Our endovascular retrieval of the equipment was successful, and we achieved access-site hemostasis by deploying a covered stent.

It has been suggested that severe aortic stenosis is less common in African Americans, but there are limited data from large studies.

Acutely failing bioprosthetic valves represent a clinical emergency and are exceedingly challenging given the paucity of therapeutic options. Oftentimes, these patients are not re-operative candidates due to clinical instability. We present 2 cases of acute degenerative aortic bioprosthetic valve failure with cardiogenic shock treated with transcatheter aortic valve replacement (TAVR).

Purpose: To report a case of a major vascular complication during transcatheter aortic valve replacement (TAVR) and the endovascular management thereof. Additionally, we discuss a possible correlation with long-term steroid use.
Case Report: A 79-year-old woman with a history of critical aortic stenosis underwent elective TAVR.
Schizophrenia is a debilitating neurological disorder characterized by positive, negative, cognitive and/or emotional symptoms. Decreased social interaction is a common negative symptom. Social interaction can be readily observed in rats and is therefore an ideal target behaviour when evaluating an animal model of schizophrenia.

Background: The value of a routine completion angiogram after CABG and 1-stop hybrid CABG/PCI remains unresolved.
Methods: Between April 2005 and July 2007, 366 consecutive patients underwent CABG surgery, with (n = 112) or without (n = 254) concomitant 1-stop PCI (hybrid), all with completion angiography before chest closure.
In the last few decades, the increase in the prevalence of type 2 diabetes mellitus has reached epidemic proportions in the Western world. A similar, though delayed, pattern is seen in developing countries. Chronic hyperglycemia, dyslipidemia, and insulin resistance have been associated with an accelerated form of atherogenesis, characterized by a prothrombotic state, enhanced inflammation, and endothelial dysfunction.

Methods And Results: A pooled analysis of 5 randomized intravenous GP IIb/IIIa inhibitor trials (EPIC, EPILOG, EPISTENT, IMPACT II, and PURSUIT) was performed, and outcomes of graft interventions were assessed at 30 days and 6 months. Compared with PCI of native circulation (n=13 158), graft interventions (n=627) were associated with worse outcomes and in particular with a doubling of mortality at 30 days (2.
