BACKGROUND In high-risk coronary artery bypass patients; off-pump versus on-pump surgical strategies still remain a matter of debate, regarding which method results in a lower incidence of perioperative mortality and morbidity. We describe our experience in the treatment of high-risk coronary artery patients and compare patients assigned to on-pump and off-pump surgery. METHODS From March 200...

We performed redo-off-pump coronary artery bypass grafting( OPCAB) via a left thoracotomy using the PAS-Port system for proximal vein graft anastomoses in a patient with posterolateral myocardial ischemia. The patient was a 76-year-old man who had undergone coronary artery bypass grafting (CABG)[ left internal thoracic artery( LITA)-left anterior descending artery( LAD), saphenous vein graft(SV...

he Randomized On Versus Off Bypass (ROOBY) Tstudy group has produced another interesting article [1]. They used complex and appropriate analytic methods in a cost-effectiveness study of the ROOBY trial [2]. This randomized control trial compared on-pump coronary artery bypass graft surgery (CABG) and off-pump coronary artery bypass graft surgery (OPCABG) in a large cohort of low-risk male patie...

Background: With the evolution of anesthesia and surgical procedures, fast track extubation has gained an increased interest, mainly based on the possibility of reducing health costs seemingly without compromising patient care. Aim: To compare two groups of patients submitted to a non-fast track extubation and a fast track extubation protocol after coronary artery bypass graft surgery with card...

OBJECTIVE Preoperative measurements of collateral blood flow in patients with triple vessel disease and chronic occlusions of the right coronary artery do not, currently, ascertain the need to revascularise an occluded right coronary artery. We performed direct measurements of flow across left coronary bypass grafts to determine their contributions to collateral blood flow. METHODS Collateral...

The use of a composite graft with left internal thoracic artery (LITA) and arterial or saphenous vein (SV) grafts can allow the complete revascularization of the left coronary system (LCS) without cardiopulmonary bypass (CPB) and without ascending aorta manipulation (AAM), in order to reduce some complications in the immediate postoperative. This study shows 8-year angiographic follow-up result...

BACKGROUND The ratio of early transmitral flow velocity to early diastolic velocity of the mitral annulus (E/e') correlates with left ventricular (LV) filling pressure. In particular, an E/e' ratio more than 15 is an excellent predictor of increased LV filling pressure. The authors evaluated the prognostic implications of preoperative estimated LV filling pressure, assessed by E/e' ratio, in pa...

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...

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.
