Impact of obesity on outcome of patients undergoing off-pump coronary artery bypass grafting using aorta no-touch technique.

We prospectively examined 1359 adult patients undergoing isolated coronary revascularization with the Pi-circuit technique, consisting of beating heart, aorta no-touch, use of composite grafts, and off-pump arterial revascularization. Patients were divided into two groups based on body weight; Group A consisting of 295 (21.7%) obese patients [body mass index (BMI) > or =30 kg/m(2)] and Group B of 1064 (79.

Aorta no-touch off-pump coronary artery revascularization in octogenarians: 5 years' experience.

Background: Approximately 18% of octogenarians have ischemic heart disease. Increasingly, they are being referred for coronary artery revascularization by surgical and/or percutaneous procedures. These strategies have been questioned, however, because of reports of poor outcomes in the elderly.

Predictors of prolonged mechanical ventilation following aorta no-touch off-pump coronary artery bypass surgery.

Objective: To identify parameters associated with prolonged mechanical ventilation (PMV) (>48 h) after off-pump coronary artery bypass (OPCAB) in our patient population.

Materials And Methods: From February 2001 to November 2005, we operated on 1359 patients for isolated coronary revascularization with the pi-circuit technique, consisting of: (1) beating heart, (2) OPCAB, (3) aorta no-touch, (4) use of composite grafts, and (5) arterial revascularization.

Results: From the total number of our patients, 1320 patients had been extubated within 48 h postoperatively (Group A) and 39 patients needed PMV (Group B).
