title: Mitral valve injury during balloon valvuloplasty for an infant with severe aortic stenosis: spatial evaluation using three-dimensional echocardiography.
abstract: We report on a 4-month-old infant with mitral valve injury that was induced by percutaneous balloon valvuloplasty for severe aortic valve stenosis. Three-dimensional echocardiography revealed a laceration at the anterior leaflet of the mitral valve. The mitral valve injury was successfully repaired by surgical operation 1 year after the valvuloplasty. This unexpected complication is associated with anatomical disorders of congenital aortic stenosis, including hypoplastic left ventricle, short chordae tendae, and large papillary muscles.
