[Aortic valve-sparing operation for chronic dissecting aneurysm of the sinus of valsalva associated with redissection in a young woman who experienced out-of-hospital cardiac arrest].

A 38-year-old woman was admitted to our hospital because she experienced cardiopulmonary arrest at her wedding;her cardiac beats were resumed 20 min after cardiopulmonary resuscitation performed by her relatives and hotel staffs. Enhanced computed tomography revealed acute aortic redissection in chronic dissecting aneurysm in the right sinus of Valsalva, which was believed to have occurred in the 4th month of pregnancy 2 years before. Echocardiography showed moderate aortic regurgitation. We performed aortic valve-sparing operation and ascending aortic replacement with partial remodeling of the right sinus of Valsalva. She returned to work 2 months later without high-order dysfunction.
