Developing a genetic fuzzy system for risk assessment of mortality after cardiac surgery.

Cardiac events could be taken into account as the leading causes of death throughout the globe. Such events also trigger an undesirable increase in what treatment procedures cost. Despite the giant leaps in technological development in heart surgery, coronary surgery still carries the high risk of the mortality.

Predictors of blood transfusion in patients undergoing coronary artery bypass grafting surgery.

Objectives: The aim of this retrospective study is to identify intraoperative patient's characteristics predicting the need for blood transfusion during CABG in our local cardiac surgical service.

Methods: This study included 1835 consecutive patients, 1311 males and 524 females with mean age 58.8±9.

Comparison of endoscopic versus conventional internal mammary harvesting regarding unligated side branches.

Background: In an effort to minimise access in cardiac surgery, endoscopic vessel harvesting has become more popular. The endoscopic approach, however, allows for only the harvest of the mid to distal internal mammary artery (IMA), leaving the more proximal branches of the conduit available for collateral flow away from the coronary bed.

Aim: To compare the number and anatomic variation of remaining side branches in thoracoscopic vs.

Scoring system for predicting saphenous vein graft patency in coronary artery bypass grafting.

The initial and long-term benefits of coronary artery bypass grafting depend upon maintaining the coronary blood flow supplied by the graft. In order to devise a scoring system for predicting graft patency, we evaluated presumptive correlations between saphenous vein graft patency and the characteristics of saphenous veins that were used as conduits in coronary revascularization.We prospectively evaluated 1,000 saphenous vein segments that were implanted in 403 consecutive patients who underwent on-pump coronary artery bypass grafting at our hospital from January 2006 through February 2009.

Echo rejection score: new echocardiographic approach to diagnosis of heart transplant rejection.

Objective: The gold standard test in the diagnosis of heart transplant rejection is right ventricular (RV) myocardial biopsy, which is an invasive, time-consuming, expensive method. In an effort to find a reliable method to minimise the sequential use of myocardial biopsy, we assessed the main echocardiographic indices for the detection of allograft rejection.

Materials And Methods: Fifty myocardial specimens were examined in this prospective study, which assessed the prominent echocardiographic parameters propounded by previous studies as indicators of rejection.

The 64-multislice computed tomogram averts misdiagnosis of an anomalous origin of the left main coronary artery.

A 38-year-old woman was discovered to have a systolic murmur for an unrelated complaint. Transesophageal echocardiography showed no atrial or ventricular septal defects, but multiple large collateral vessels in inter-ventricular septum. The origin of left coronary artery was not seen at the expected site on the aortic root.

Heart transplantation in iran; a comprehensive single-center review of 15-year performance.

Background: Heart transplantation in Iran was first performed in July 1993. Since then, Shariati Hospital, affiliated to Tehran University of Medical Sciences, has been representing the most active center of cardiac transplantation in Iran and one of the major sites in the Middle East. This is a comprehensive review of our 15-year practice registry to make a scheme of our record and achievements.

Transient bilateral cortical visual loss after coronary artery bypass grafting in a normotensive risk-free patient.

Background: Postoperative blindness has been mentioned as a rare complication of heart surgery. The majority of reported cases are caused by retinal artery occlusion or ischemic optic neuropathy. We report a case of transient visual loss due to cortical ischemia after coronary artery bypass grafting (CABG).
