INTRODUCTION AND OBJECTIVES The transient myocardial ischemia that occurs during cardiac surgery leads to oxidative stress and the production of free radicals. The resulting damage can be reduced if cardiopulmonary bypass is avoided. We obtained indirect measures of the oxidative damage occurring during cardiac surgery by monitoring the glutathione system and we studied the influence of cardiop...

myocardial bridging with systolic compression of the left anterior descending coronary artery (lad) may be associated with myocardial ischemia. in symptomatic myocardial bridging unresponsive to medical treatment, surgical unroofing of the left lad can be performed. little information is available about the long-term prognosis of patients with this coronary anomaly after the surgical unroofing,...

BACKGROUND Hyperglycemia is commonly present in the perioperative period in patients undergoing cardiac surgery, even during administration of insulin. A direct relationship between postoperative hyperglycemia and mortality has been established in diabetic patients undergoing cardiac surgery. However, this relationship might be confounded because patients with poor outcome receive more glucogen...

BACKGROUND Despite the continuing improvements in surgical and cardiopulmonary bypass techniques during cardiac surgery, stroke remains a devastating complication. This study aimed to identify the preoperative and intraoperative risk factors for developing a perioperative stroke in patients undergoing coronary artery bypass graft surgery on cardiopulmonary bypass. METHODS A total of 4,380 con...

Background : Quests for doing coronary artery bypass surgery by a technique with lower complications is going on, for this aim many studies compared patients undergoing CABG with or without cardiopulmonary bypass. This study was carried out to compare laboratory findings after coronary artery bypass in these two groups of patients. Materials and Methods: In a retrospective study, 167 patients ...

A 72-year-old man with an ejection fraction of 25% is scheduled to undergo elective coronary artery bypass graft using cardiopulmonary bypass. Because of the high-risk nature of the operation, the surgeon wants to insert an intraaortic balloon pump (IABP) before initiating cardiopulmonary bypass. An intraoperative transesophageal echocardiogram (TEE) is requested to ensure correct placement.
