OBJECTIVE Previous work has found cerebral oxygen extraction to decrease during hypothermic cardiopulmonary bypass in children. To elucidate cardiopulmonary bypass factors controlling cerebral oxygen extraction, we examined the effect of perfusate temperature, pump flow rate, and hematocrit value on cerebral hemoglobin-oxygen saturation as measured by near infrared spectroscopy. METHODS Forty...

BACKGROUND Whether off-pump coronary artery bypass grafting has a late renal protective advantage over conventional coronary arterial bypass grafting with cardiopulmonary bypass use is controversial. METHODS From 1997 to 2004, 2102 cases of isolated coronary arterial bypass grafting were collected and analyzed, 1116 (53%) in the cardiopulmonary bypass group and 986 (47%) in the off-pump coron...

OBJECTIVE Postoperative atrial fibrillation (AF) is still frequent complication after cardiac surgery in spite of the improvements in the surgical procedures. There is still controversy whether or not, the absence of cardiopulmonary bypass results in a lower incidence of AF. METHODS Six hundred and seventy patients that underwent revascularization by using in situ LIMA for single vessel disea...

patients with coronary artery disease and left ventricular dysfunction have high mortality with non surgical (medical) treatment. coronary artery bypass grafting improves survival and the quality of life. recently, revascularization without cardiopulmonary bypass has been presented as a viable alternative. the aim of this study was to survey the result of coronary artery bypass grafting with of...

Percutaneous aortic valvuloplasty is reportedly a useful tool for the management of critical and severe aortic stenosis with cardiogenic shock. However, early percutaneous coronary intervention for cardiogenic shock is beneficial for elderly patients with acute myocardial infarction. We describe a patient with critical aortic stenosis who presented with severe coronary stenosis of the left main...

Surgical treatment for diffusely diseased coronary arteries has been considered to be a relative contraindication for off pump coronary artery bypass (OPCAB) grafting. We report a case of off pump long-onlay-bypass grafting using the left internal mammary artery. To our knowledge, the long-onlay-patch grafting with OPCAB technique has not been previously described. Two sets of Octopus-3 tissue ...

BACKGROUND Emphasis on cost containment in coronary artery bypass surgery is becoming increasingly important in modern hospital management. The revival of interest in off-pump (beating heart) coronary artery bypass surgery may influence the economic outcome. This study examines these effects. METHODS Two hundred patients undergoing first-time coronary artery bypass surgery were prospectively ...

Background: Liver dysfunction during on-pump coronary artery bypass graft surgery (CABG) is a rare complication but is associated with significant morbidity and mortality. The ability to identify high-risk patients may be helpful in planning appropriate management strategies. We aimed to evaluate the factors influencing liver function tests during on-pump CABG.Methods: In 146 patients scheduled...

BACKGROUND Off-pump coronary artery bypass grafting compared with coronary revascularization with cardiopulmonary bypass seems safe and results in about the same outcome in low-risk patients. Observational studies indicate that off-pump surgery may provide more benefit in high-risk patients. Our objective was to compare 30-day outcomes in high-risk patients randomized to coronary artery bypass ...

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...
