Abstract: A 78-year-old woman was referred to our hospital because of progressive exertional dyspnea due to nonrheumatic severe aortic valve stenosis and moderate mitral valve stenosis with mitral annular calcification. We subsequently performed aortic valve replacement and mitral anterior leaflet decalcification. During surgery, we found that the cause of mitral valve stenosis was calcification of A2 aortic curtain-medial trigon through aortic valve annulus and resected calcification with SONOPET. The postoperative echocardiography revealed good mitral valve motion with mild mitral valve stenosis.
