Early graft patency after off-pump and on-pump coronary bypass surgery: a prospective randomized study.

Aims: Uncertainty persists regarding the impact of the off-pump technique on coronary bypass graft patency. The primary objective of this study was to assess coronary artery bypass graft patency in patients randomized to off-pump and on-pump multivessel coronary artery bypass grafting (CABG). Secondary objectives were clinical outcomes and neuropsychological functioning.

Off-pump coronary artery bypass surgery in women.

Objective: Gender is a well-known risk factor for mortality and morbidity after coronary artery bypass grafting and various reasons have been proposed to explain the poorer results observed in women. The study objective was to determine whether female gender was still an operative risk factor with the adoption of off-pump coronary artery bypass surgery.

Methods: Of 2123 consecutive patients who underwent isolated CABG between November 2002 and December 2007, 1966 (92.

Sixteen-slice multidetector computed tomography for graft patency evaluation after coronary artery bypass surgery.

Objective: To investigate the ability of 16-slice multidetector computed tomography (MDCT) to assess coronary artery bypass graft patency and to detect bypass stenosis by comparison with coronary angiography.

Methods: Thirty patients underwent both conventional coronary bypass angiography and retrospective ECG gated 16-slice multidetector computed tomography after surgery using 0.4 seconds rotation time and 1.

Less invasive coronary artery bypass surgery: early results in 1083 patients operated off-pump.

Objective: To analyze the early results of coronary surgery without cardiopulmonary bypass using the EuroSCORE risk model.

Methods: Out of a series of 1104 consecutive patients undergoing CABG during a 20-month period and whose data were prospectively collected, 1083 patients (98.1%) were operated without cardiopulmonary bypass (CPB) and represent the patient population.

Coronary surgery: which method to use?

Objective: To compare 4 methods of myocardial protection in GABG in terms of markers of myocardial ischemia, mortality, morbidity and mid-term results.

Material & Methods: Retrospective study of 241 consecutive patients undergoing isolated > 1 CABG using one of 4 methods: off-pump (OFF, n = 108), cardiopulmonary bypass (CPB) and cardioplegia (CARD, n = 66), CPB and beating heart (BEAT, n = 47), or CPB and ventricular fibrillation (FIBR, n = 20). Mean age was 65.

Coronary surgery in patients with porcelain aorta.

Four patients with unstable angina due to left main or three-vessel disease scheduled for coronary artery bypass grafting were found intra-operatively to have porcelain ascending aorta, defined as massive calcification of the ascending aorta from the aortic valve to the transverse arch, precluding ascending aorta cannulation or clamping. A no-touch operative technique was applied using the two internal mammary arteries in three cases, with complementary Y-grafting when necessary. Three cases underwent off-pump myocardial revascularization.

Cardiac surgery and morbid obesity.

Objective: Obesity is considered a risk factor for the occurrence of complications after cardiac surgery. The objective of this study was to analyze mortality and morbidity in patients with morbid obesity following heart surgery.

Design: Retrospective study in a tertiary care setting.
