Pulmonary vein isolation procedure was performed for atrial fibrillation associated with mitral valve disease in twelve patients. This simple procedure consisted of only isolation of the four pulmonary veins. Combined mitral valve surgery consisted of mitral valve plasty, mitral valve replacement with or without aortic valve replacement and tricuspid annuloplasty. Ten patients returned to a sinus rhythm. Two patients required DDD pacemaker implant for sick sinus syndrome. Left atrial contraction was detected in eight cases by trans-esophageal echography. Compared with the maze procedure, this operation was less invasive and preserved atrial appendage, helping to maintain normal secretion of atrial natriuretic peptide. This study suggests that the pulmonary vein isolation procedure may be an effective and simple maneuver for atrial fibrillation associated with mitral valvular disease.
