Mitral Valve Regurgitation Exacerbated by Aortic Dissection：Report of a Case

はじめに　Stanford A型急性大動脈解離（acute aortic dissection：AAD）の緊急手術に際し，僧帽弁の同時手術の報告はめずらしい．

The patient was a 74-year-old woman who was originally followed up for hypertrophic cardiomyopathy and mitral regurgitation without subjective symptoms. With the onset of acute aortic dissection, the mitral regurgitation was exacerbated with systolic anterior motion. In addition to aortic dissection surgery, mitral valve surgery was performed. The mitral valve was approached through a right-sided left atrial incision and replaced with a bioprosthetic valve. For aortic dissection, ascending aortic replacement was performed. The postoperative course was uneventful, and the patient was discharged on foot after rehabilitation. Simultaneous mitral valve surgery for acute aortic dissection is rare, but by intervening simultaneously, we were able to achieve a favorable postoperative course.
