Reconstructive valve surgery in acute aortic dissection type A (AADTA) remains challenging. We describe a case of successful combined repair of the aortic and mitral valves, and replacement of the ascending aorta after AADTA with aortic and mitral insufficiency. Mitral valve repair was achieved by quadrangular resection of the posterior leaflet, combined with ring annuloplasty. Aortic valve repair was achieved by Cabrol commissural sutures with resuspension of the annulus. The postoperative clinical course was uneventful and an echocardiogram revealed competent mitral and aortic valves. Mitral and aortic valve repair is an option in AADTA with mitral and aortic valve insufficiency.
