Over the past decade, we have experienced the offshore migration of early device evaluation at a time when first-in-human clinical trials to evaluate novel cardiology devices have nearly ceased in…
Abstract We encountered a case of late regression after sirolimus-eluting stent restenosis. We report this case with intravascular ultrasound imaging demonstrating an intraluminal echolucent tissue, which looks like a black…
Abstract Peripheral embolization is a known complication of peripheral artery interventions. It can lead to occlusion of distal vessels leading to significant lower extremity ischemia and complications. Peripheral artery interventions…
Abstract Platelets play a pivotal role in normal hemostasis, and derangement of their function can lead to hemorrhage or thrombosis. While progress has been made in elucidating the molecular mechanisms…
Abstract Some severe calcified coronary lesions may resist the advancement of the stent despite rotational atherectomy and balloon predilation, when used via the transradial approach due to a lack of…
Abstract Coronary artery perforation (CAP) is an infrequent yet a very dangerous complication of percutaneous coronary intervention. We describe the successful treatment of a guidewire-induced distal coronary branch vessel perforation…
Abstract Background Loss of side-branch vessels is a serious complication following stent implantation in parent vessels of bifurcation lesions. The purpose of this study was to introduce and test a…
Abstract Background Intramural delivery of lipids into the coronaries of pigs fed high-cholesterol diet results in the formation of localized atherosclerotic-like lesions within 12 weeks. These lesions are located in…
Abstract Background Preinfarction angina (PA) is a clinical analogue of ischemic preconditioning that improves postinfarct prognosis. Data concerning the association of PA with post infarction left ventricular (LV) remodeling and…
Abstract Background Patients undergoing percutaneous coronary intervention (PCI) who are at high risk for cardiovascular collapse during the procedure may benefit from prophylactic circulatory support. The objective was to evaluate…
