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...

BACKGROUND There is renewed interest in coronary artery bypass grafting without cardiopulmonary bypass using the anterolateral minithoracotomy approach. We evaluated 209 patients who underwent minimally invasive direct coronary artery bypass grafting using an anterolateral minithoracotomy. The anastomosis was performed under direct vision on the beating heart without using cardiopulmonary bypas...

BACKGROUND The effect of the use of coronary-artery bypass surgery without cardiopulmonary bypass and cardiac arrest ("off pump") on graft patency remains uncertain. We undertook a prospective, randomized, controlled study to compare graft-patency rates and clinical outcomes in off-pump surgery with conventional, "on-pump" surgery. METHODS We randomly assigned 50 patients to undergo on-pump c...

Title: Respiratory physiotherapy and incidence of pulmonary complications in off-pump coronary artery bypass graft surgery: an observational follow-up study

BACKGROUND The significance and clinical role of cardiac troponin testing after coronary artery bypass grafting remain unclear. METHODS AND RESULTS Cardiac troponin T (cTnT) was measured during the first 24 hours after coronary artery bypass graft surgery in 847 consecutive patients. Only 17 patients (2.0%) had new Q waves or left bundle-branch block after surgery; however, cTnT elevation was...

background  : on-pump coronary artery bypass graft (cabg) surgery impairs gas exchange in the early postoperative period. the main object on this study was evaluation of changes in arterial blood gas values in patients underwent on pump cabg surgery receiving different dose of intravenous nitroglycerin (ntg). methods : sixty-seven consecutive patients undergoing elective on-pump cabg randomly e...

Introduction: Although coronary endarterectomy is not an ideal procedure, it is the only available option for cardiac surgeons in some patients with diffuse coronary artery disease. Based on the majority of conducted studies, the results of coronary endarterectomy (including survival, graft patency, and recurrence of the symptoms of myocardial ischemia) are less prevalent than standard coronary...

introduction: coronary artery disease (cad) is the most common type of heart disease, with a mortality rate of 385,000 person per year in the united states. there are two main methods for cad treatments: angioplasty and bypass surgery. coronary artery bypass grafting (cabg) is one of the greatest surgical operations of the 20th century and it is presented as most effective and long-term therapi...

The development of left atrial myxoma after coronary artery bypass graft surgery is a rare entity. A 60-year-old man with previous off-pump coronary artery bypass grafting four years ago with patent coronary grafts was diagnosed with left atrial mass. The patient underwent successful resection of the same through minimally invasive right anterolateral thoracotomy. Histopathology of the atrial m...
