a 55-year-old man referred for cardiac resynchronization therapy (crt) due to severe heart failure. a severe stenosis in the coronary sinus vein after the posterior branch disallowed the insertion of the lead. nevertheless, the stenosis was dilated and the left ventricle (lv) lead was implanted in the lateral marginal branch.

a 73-year-old woman who had undergone coronary artery bypass grafting for coronary artery stenosis six years ago, presented with right lower extremity claudication. angiography revealed right external artery stenosis. elective external iliac ptca was performed complicated with simultaneous external iliac artery and vein rupture that was an exceedingly rare event. retroperitoneal laparotomy with...

Chest pain is a typical symptomof ischemic coronary artery diseases. Patients with ischemic coronary artery diseases typically have coronary artery stenosis, although approximately 10–20% of patients with angina pectoris have normal coronary artery, and most of these patients are syndrome X that showed slow coronary flow [1,2]. In addition, patients with chest pain butwith an intact coronary ar...

BACKGROUND Vein graft stenosis after coronary artery bypass grafting (CABG) is common. Identifying genes associated with vein graft stenosis after CABG could reveal novel mechanisms of disease and discriminate patients at risk for graft failure. We hypothesized that genome-wide association would identify these genes. METHODS We performed a genome-wide association study on a subset of patients...

Introduction Left innominate stricture or stenosis after hemocatheter insertion or pacemaker lead insertion is not an uncommon vascular complication. However, spontaneous left innominate venous stricture has not been reported. We present a case with spontaneous left innominate vein stenosis in a patient with history of open heart surgery during pacemaker implantation. Retrograde channel from th...

BACKGROUND The application of previous magnetic resonance (MR) angiography techniques has enabled noninvasive differentiation between patent and occluded coronary artery bypass grafts. However, the detection of graft stenosis remains difficult. The purpose of our study was to determine the accuracy of high-resolution navigator-gated 3-dimensional (3-D) MR angiography in detecting vein graft dis...

OBJECTIVE To investigate transthoracic Doppler echocardiography in the identification of coronary artery bypass graft (CABG) flow for assessing graft patency. DESIGN The initial study group comprised 45 consecutive patients with previous CABG undergoing elective cardiac catheterisation for recurrent ischaemia. The Doppler variables best correlated with angiographic graft patency were then tes...

The saphenous vein is one of the most commonly used conduits during coronary artery bypass grafting. Saphenous vein graft markers have been introduced to facilitate coronary angiography procedures in the follow-up of patients with ischaemic heart disease. However, today these markers have only a historical aspect. This report presents a 61-year-old patient who had undergone coronary artery bypa...

Although the serum lipoprotein fraction Lp(a) has been associated with coronary artery atherosclerosis, its relationship to narrowing of saphenous vein grafts has not previously been elucidated. We therefore measured serum Lp(a) levels in 167 symptomatic patients undergoing cardiac catheterization who had had coronary artery bypass surgery 0.7 to 14.3 years earlier. Lp(a), total cholesterol, an...

conclusion the open-cell stent is effective and its performance is higher than that obtained with the closed-cell stent for treating central vein stenosis or occlusion in hemodialysis patients. results for the open-cell stent group, 159 patients were diagnosed as central vein stenosis and 98 were occlusion. for the closed-cell stent group, 78 were stenosis and 66 were occlusion. there were two ...
