Twenty four patients with 65 coronary artery bypass grafts were studied by computed tomography and angiogrphy within a 10 day period in order to assess graft patency and graft flow. In the assessment of graft patency computed tomography had an accuracy of 93% and in that of graft flow one of 91%. These results indicate that computed tomography is an accurate method for assessing graft patency a...

OBJECTIVE To determine whether optimism predicts lower rates of rehospitalization after coronary artery bypass graft surgery for the 6 months after surgery. METHODS A prospective, inception cohort design was used. The sample consisted of all consenting patients (N=309) from a consecutive series of patients scheduled for elective coronary artery bypass graft surgery at a large, metropolitan ho...

BACKGROUND The incidence of anterior ischemic optic neuropathy after coronary artery bypass graft procedures ranges from 1.3 to 0.25%. The mechanisms of anterior ischemic optic neuropathy after cardiovascular procedures remain undefined but many systemic and related-to-surgery risk factors could underlie anterior ischemic optic neuropathy. In this case, we report a rare presentation of a bilate...

BACKGROUND In severe coronary artery disease, coronary artery bypass grafting (CABG) surgery is indicated to re-establish an adequate blood supply to the ischemic myocardium. Effectiveness of CABG surgery for symptom relief and mortality decrease should therefore depend on bypass graft patency. As bypass using a left internal mammary artery (LIMA)-to-left anterior descending coronary artery (LA...

OBJECTIVES The aim of this article is to make an evaluation on the clinical features of patients with Kawasaki disease who require a cardiac surgical procedure including coronary artery bypass grafting, coronary arterial aneurysmorrhaphy or heart transplantation. METHODS English literature of Kawasaki disease for cardiac surgery (1990-2011) was retrieved in the Pubmed database. The clinical f...

In the previous issue of Critical Care, Yu and colleagues report increased morbidity and mortality in patients after myocardial infarction undergoing prophylactic intra-aortic balloon pump support before coronary artery bypass graft surgery. The impact of prophylactic intra-aortic balloon pump implantation before coronary artery bypass graft therapy still is controversially debated. However, Yu...

A 47-year-old male patient with 3-vessel coronary artery disease underwent quadruple coronary artery bypass graft surgery (right internal mammary artery–right coronary artery [RIMA–RCA], left internal mammary artery–left anterior descending artery [LIMA–LAD], and radial artery– second posterolateral branch with jump anastomosis to the first posterolateral branch). Surgery was complicated by dif...

OBJECTIVE To investigate the effect of 6 weeks' pre-operative treatment with the angiotensin converting enzyme inhibitor, quinapril, on left ventricular function when measured 3 months after coronary artery bypass graft surgery and to examine the safety of such treatment. PATIENTS AND METHODS Patients (96) [86 males, 10 females; mean age 61 years] with chronic stable angina, on the waiting li...

in this theoretical study, the effect of various types of bypass graft angles on the flow field, has been investigated specially on the temporal wall shear stress (wss) on the toe, heel and some locations on the bed of the left anterior descending (lad) artery at the anastomoses areas in the aorto-coronary (ac) and coronary-coronary (cc) bypasses. flow fields in both bypasses with angles of 20º...
