Saphenous vein bypass pseudoaneurysm is rare but fatal complication after coronary bypass surgery. Pseudoaneurysm is managed either with a surgical or percutaneous approach. This patient underwent quadruple coronary artery bypass grafting 10 years earlier and was referred for recurrence of angina. Coronary and graft angiography revealed a pseudoaneurysm in the saphenous vein graft supplying the...

m U b w d i ( d S d i c s i p l s ( he left main coronary artery’s critical importance o coronary circulation has focused attention on his specific anatomical subgroup for decades. In he early 1970s, coronary artery bypass graft CABG) was found to improve late survival in atients with significant left main stenosis in comarison with medical therapy (1–3). Once CABG ecame the standard of care fo...

Different suture techniques have been used for anastomosis in coronary artery bypass graft surgery. Bypass surgery may be difficult for patients who have small coronary arteries or marked size discrepancies between target coronary arteries and grafts. For proximal and distal anastomoses, three continuous stitches are first placed in the heel and toe of the small coronary arteries; for sequentia...

BACKGROUND Increasingly studies have identified socioeconomic factors adversely affecting healthcare outcomes for a multitude of diseases. To date, however, there has not been a study correlating socioeconomic details from nationwide databases on the prevalence of advanced coronary artery disease. We seek to identify whether socioeconomic factors contribute to advanced coronary artery disease p...

OBJECTIVES Patients with coronary artery disease and left ventricular dysfunction have high mortality when kept in clinical treatment. Coronary artery bypass grafting can improve survival and the quality of life. Recently, revascularization without cardiopulmonary bypass has been presented as a viable alternative. The aim of this study is to compare patients with left ventricular ejection fract...

Non-Newtonian fluid flow in a stenosed coronary bypass is investigated numerically using the Carreau-Yasuda model for the shear thinning behavior of the blood. End-to-side coronary bypass anastomosis is considered in a simplified model geometry where the host coronary artery has a 75% severity stenosis. Different locations of the bypass graft to the stenosis and different flow rates in the graf...
