Influence of external temporary biatrial pacing on the prevention of atrial fibrillation after coronary artery bypass without extracorporeal circulation.

Background: Atrial fibrillation is the most common complication after myocardial revascularization, and it increases morbidity/mortality.

Objective: The purpose of this prospective randomized study was to test the hypothesis that temporary biatrial pacing is effective in reducing the incidence of postoperative atrial fibrillation after myocardial revascularization.

Methods: Ninety-eight non-consecutive patients who had undergone off-pump myocardial revascularization received two temporary electrodes attached to the right and left atria, which were connected to either pair of atrial pacemaker electrodes, in addition to the leads implanted in the right ventricle.

Analysis of the immediate outcomes of a comparative randomized study between aorto-saphenous mechanical anastomosis versus conventional anastomosis.

Objective: To evaluate the immediate results of mechanical aorto-saphenous anastomosis compared with conventional anastomosis.

Method: We evaluated 12 patients. The mean age ranged from 62.

OPCAB in patients on hemodialysis.

Objective: To analyze the hospital outcomes of patients, with chronic renal insufficiency in the hemodialysis, submitted to OPCAB.

Method: Fifty-one patients with chronic renal insufficiency were submitted to OPCAB. Hemodialysis was performed on the day before and the day after the operation.
