[A case of atypical aortic coarctation with mitral and aortic regurgitation and ascending aortic dilatation].

A 67-year-old female presented with dyspnea on exertion as a chief complaint. Diagnosed as having severe mitral regurgitation, aortic regurgitation, dilatation of the ascending aorta and atypical coarctation due to aortitis syndrome, she underwent mitral valve replacement, aortic valve replacement, ascending aorta and hemiarch replacement and ascending aorta-abdominal aorta extraanatomical bypass in one stage. Pathologically, typical findings of aortitis syndrome were not observed in the wall of the ascending aorta and aortic valve, but cystic medionecrosis was noted in the wall of the ascending aorta. Follow-up observations are needed for the remaining aortic wall.
