[Risk factors for postoperative atrial fibrillation after coronary artery bypass grafting. A prospective analysis].

Background: Atrial fibrillation (AF) is a relevant complication after coronary artery bypass grafting (CABG). However there is controversy regarding possible contributing factors.

Aim: To study the incidence of AF, its risk factors and its repercussion on hospital stay and charges, in patients undergoing CABG.

[Cryoablation of pulmonary veins as complementary treatment of atria I fibrillation in valvular surgery].

Background: The Cox MAZE III operation for the treatment of atrial fibrillation (AF) is complex and consumes significant operative time. Cryoablation of the pulmonary veins (CPV) is a simpler alternative for patients that require concomitant valvular surgery.

Aim: To evaluate CPV in patients with AF submitted to valvular surgery.

[Partial or total replacement of the aortic arch. Experience in 23 patients].
