Aortic valve repair for adult congenital heart disease: A 22-year experience.

abstract：BACKGROUND:The incidence, determinants, and outcome of postoperative atrial fibrillation (AF) after surgery for mitral regurgitation (MR) are poorly defined but may have important implications for timing of mitral valve surgery. METHODS AND RESULTS:In 762 patients in sinus rhythm with no AF history undergoing MR surgi...
