[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.
