[Pulmonary vein isolation using cut and sew technique].

We reviewed our cut and sew pulmonary vein isolation (PVI) series for chronic or paroxysmal atrial fibrillation (Af). Intraoperative evaluation of sinus nodal function with electrical defibrillation and atrial pacing and the incision to mitral annulus adding to PVI were important factors to restore sinus rhythm. Ninety-two percent of the patients with the good sinus nodal function restored sinus rhythm. These findings will be useful information for surgical ablation of Af with or without new energy sources.
