Objectives: many studies have shown that oral beta blockers reduce the incidence of atrial fibrillation after coronary artery bypass. The goal of this study was to determine whether landiolol, an intravenous beta blocker, reduces the incidence of atrial fibrillation after off-pump coronary artery bypass. Methods: 39 consecutive patients were given ...

Cellular adhesion on the surface of Guglielmi detachable coils (GDC) promotes accelerated occlusion of aneurysms. We hypothesized that coils coated with transforming growth factor beta (TGF-beta) and vascular endothelial growth factor (VEGF) will promote clot organization and endothelial or cellular proliferation to facilitate closure of large experimental aneurysms relative to ...

Anomalous coronary arteries pose a great challenge during percutaneous intervention due to various technical factors. Inadequate guide support leads to significant obstacles for delivery of interventional devices to stenotic areas. Several methods have been proposed to overcome these obstacles. We present a novel technique where we used the Guideliner support ...

SUMMARY:We report a novel model of arterial tortuosity in the porcine brachial artery for testing of endovascular devices in the flexed forelimb position. This provides an ideal vascular territory for an in vivo assessment of guidewires, microcatheters, and endovascular implants because it closely mimics the challenging curvature at the carotid ...

Actin polymerization (APM), regulated by Rho GTPases, promotes myocyte force generation. Hypoxia is known to impede postnatal disassembly of the actin cytoskeleton in pulmonary arterial (PA) myocytes. We compared basal and agonist-induced APM in myocytes from PA and descending aorta (Ao), under hypoxic and normoxic conditions. We also examined effects ...

Stenting of curved arteries is generally perceived to be more challenging than straight vessels. Conceptually implanting multiple shorter stents rather than a single longer stent into such a curved artery represents a promising concept, but little is known about the impact of such an approach. The objective of this study ...

Recanalization of chronic total occlusions via grafts has been described previously. However, the insertion of the graft into the distal vessel is often characterized by an unfavorable entry angle which renders an antegrade approach challenging. In the present case, we describe how retrograde recanalization of the proximal right coronary artery ...

Arterial prosthetic graft infection is one of the most challenging issues in vascular surgery. We report a case of an infected descending thoracic aorta endograft, presenting itself several years after placement, with hemoptysis and back pain as referred symptoms. The patient was successfully treated by removing the thoracic aorta and ...

Many congenital heart defects require reconstruction of the right ventricular outflow tract utilizing a right ventricle to pulmonary artery conduit. One of the challenges with these conduits is the development of conduit stenosis. This phenomenon is quite common and typically results from a combination of progressive calcification, fibrosis, and/or the ...

Bifurcation lesions of native coronary arteries are common in daily practice and different strategies for percutaneous coronary intervention have been suggested for their treatment. The "crush" technique, with the use of drug-eluting stents in both the main and the side branch, is a relatively simple procedure that ensures complete lesion ...

Percutaneous treatment of old, degenerated saphenous vein grafts (SVG) is associated with a high likelihood of major adverse cardiac events. When an acute coronary syndrome (ACS) develops in a patient with old SVG, fresh thrombus may superimpose on an old, degenerative atheroma: a sudden increase in the athero-thrombotic burden ensues ...

A 60-year old man with a history of coronary-artery bypass grafting presented with symptoms of acute coronary syndrome. Coronary angiography revealed a huge intraluminal thrombus in the saphenous vein graft to the second obtuse marginal branch of the left circumflex artery. A glycoprotein IIb/IIIa inhibitor (tirofiban) was administered intravenously. Two ...

BACKGROUND: Endoscopic saphenous vein harvest (EVH) decreases leg wound infections and improves cosmesis after coronary artery bypass grafting (CABG). Recent data, however, suggest that EVH may be associated with reduced graft patency rates. The objective of this study is to assess the effect of EVH on short-term and midterm outcomes ...
