Long-Term Results after the Box Pulmonary Vein Isolation Procedure for Chronic Atrial Fibrillation in Mitral Valve Surgery

Abstract

The box pulmonary vein isolation procedure can terminate chronic AF associated with solitary mitral valve disease, and maintain a sinus rhythm for more than 6 years in 70% of chronic AF patients. This study implicates the pulmonary veins and posterior left atrium in maintaining chronic AF associated with mitral valve disease.
