There are two basic ways of performing coronary artery bypass graft surgery (CABG): on pump CABG and off pump CABG. Off pump CABG is relatively a newer procedure to on-pump CABG and does not require the use of the cardiopulmonary bypass machine. On pump CABG is the more traditional method of performing bypass surgery. However its resultant inflammatory effects cause renal dysfunction, gastroint...

Atrial fibrillation (AF) occurs in one quarter to one third of patients after coronary artery bypass graft surgery (CABG). Conventional CABG uses cardiopulmonary bypass, a process that is itself associated with a systemic vascular inflammatory response that contributes to postoperative morbidity. The avoidance of cardiopulmonary bypass is associated with a significant reduction in the inflammat...

Background Off-pump coronary artery bypass grafting (OPCABG) procedures can avoid the complications of an on-pump bypass. However, some cases unexpectedly require conversion to cardiopulmonary bypass during OPCABG. The risk factors associated with a sudden need for cardiopulmonary bypass were analyzed. Methods This retrospective study included 283 subjects scheduled for OPCABG from 2001 to 20...

Background: Off-pump coronary artery bypass graft (CABG) surgery is supposed to reduce perioperative mortality and morbidity compared with on-pump coronary bypass graft surgery. The causes of hemodynamic collapse during off-pump coronary artery bypass (OPCAB) remain scarcely defined. We present an analysis of 7 cases who were converted to conventional CABG due to sustained hemodynamic collapse ...

conclusions our study showed superiority of off-pump cabg regarding lvef, rvef and valves regurgitations. future studies with prospective structure, accurate randomization, longer follow up duration, and larger sample size are needed. results one hundred eighteen patients with the mean age of 59.47 ± 9.68 years were included (81 male and 37 female). on-pump cabg was done on 84 patients and off-...

OBJECTIVE To describe patient selection criteria, surgical technique and early outcomes in patients undergoing reoperative coronary artery bypass surgery (RECABG) through a left thoracotomy without cardiopulmonary bypass (CPB). METHODS Eight patients with patent grafts to the anterior interventricular branch of left coronary artery (four of which had also patent grafts to the right coronary a...

Extracorporeal circulation has led to a great development in cardiovascular surgery during the last five decades. Its time-proven efficacy and safety have made on-pump coronary artery bypass grafting (CABG) the gold standard method of surgical revascularization. However, coronary revascularization on cardiopulmonary bypass and the accompanying aortic manipulation are related to plenty of delete...

BACKGROUND Coronary artery bypass without cardiopulmonary bypass (CPB) has gained popularity recently with the development of devices that allow for improved exposure and standardization in off pump coronary artery bypass surgery. Off pump coronary artery bypass surgery reduces some of the morbidities traditionally attributed to CPB. The primary goal of off pump coronary artery bypass surgery i...

BACKGROUND Off-pump coronary artery bypass grafting has been accused of possibly compromising graft patency. Sixteen slice computed tomography has shown good diagnostic accuracy in the assessment of coronary bypass graft patency when compared with conventional coronary artery angiography and is less invasive. The study hypothesis is that coronary artery bypass grafting (CABG) performed without ...

Background: Cardiopulmonary bypass (CPB) is associated with diffuse systemic inflammatory responses during and after cardiac surgery and is associated with increased morbidity & mortality associated with Coronary Artery Bypass Grafting CABG, particularly in high risk sub set of patients i.e., advanced age, severe left ventricular dysfunction, renal failure, etc. The purpose of this study is to ...
