BACKGROUND The aim of this study was to compare intraoperative coronary graft flows performed on pump and off pump and to evaluate the effects of hemodilution on coronary graft flows in off-pump coronary artery bypass grafting (CABG) patients by using transit time flow measurements (TTFM). METHODS Three hundred patients undergoing only CABG procedures were enrolled in a prospective randomized...

BACKGROUND Sexual dysfunction is one of the most common problems in men after coronary artery bypass graft (CABG). Etiology of sexual dysfunction in these patients may be psychological or organic due to hormonal changes. OBJECTIVE The purpose was to evaluate the incidence and type of sexual dysfunction and changes in serum concentration of sex hormones in male patients undergoing on-pump CABG...

OBJECTIVE The objective of this study was to determine whether preconditioning coronary artery disease (CAD) patients with HBO(2) prior to first-time elective on-pump cardiopulmonary bypass (CPB) coronary artery bypass graft surgery (CABG) leads to improved myocardial left ventricular stroke work (LVSW) post CABG. The primary end point of this study was to demonstrate that preconditioning CAD p...

Coronary artery bypass grafting (CABG) has played an important role in the treatment of ischemic heart disease. Recently, the introduction of a drug-eluting stent (DES) has decreased the incidence of restenosis after percutaneous intervention (PCI). PCI with a DES is being increasingly performed, whereas the number of patients for whom CABG has been indicated has decreased over the last few yea...

OBJECTIVE To study the differences in the prevalence of neurological complications following coronary artery bypass (CAB) carried out by conventional, on-pump beating and off-pump techniques. METHODS A retrospective analysis of all isolated coronary bypass operations (n=127) performed in King Fahad Cardiac Center, Riyadh over a period of one year starting from January 2005. Out of 127 patient...

OBJECTIVE A cerebrovascular accident (CVA) is a devastating complication of coronary artery bypass grafting (CABG) and a major cause for morbidity and mortality. Aortic manipulation, cannulation, and clamping during CABG may lead to release of atheromatous material from the ascending aorta, which may cause a CVA. This study assessed the hypothesis that the use of intraoperative epiaortic ultras...

A prospective analysis of 421 patients undergoing coronary artery bypass graft (CABG) surgery as the sole cardiac procedure was carried out to assess the frequency of central nervous system (CNS) complications. In all, 451 variables were assessed in each patient. Stroke occurred in 5.2% but was severe in only 2%. Prolonged encephalopathy occurred in 11.6% but usually resolved before discharge. ...

The most common type of arrhythmia following coronary artery bypass graft (CABG) is atrial fibrillation (AF) with an incidence rate of 20-30%. Pericardial effusion is one of the etiologic factors of atrial fibrillation occurring after CABG. Posterior pericardiotomy (PP) causes the drainage of blood and fluids from the pericardial space into the pleural space leading to a decreased pericardial e...

OBJECTIVE Off-pump coronary artery bypass (OPCAB) surgery has become a widely accepted alternative to standard coronary artery bypass graft (CABG) surgery using cardiopulmonary bypass; however, the influence of intraoperative conversion from OPCAB to standard CABG on costs and quality of life is unclear. The objective of this study was to determine whether intraoperative conversion affects cost...

BACKGROUND Women have consistently higher mortality and morbidity than men after coronary artery bypass grafting (CABG). Whether elimination of cardiopulmonary bypass and performance of coronary artery bypass grafting off-pump (OPCAB) have a beneficial effect specifically in women has not been defined. METHODS AND RESULTS From January 1998 through March 2002, 21 902 consecutive female patient...
