Systolic anterior motion of the mitral valve after mitral valve repair without a ring.
We report a case of systolic anterior motion of the mitral valve after mitral reconstruction without a semirigid mitral annular ring. A 56-year-old man with mitral regurgitation due to ruptured chordae tendineae underwent mitral valve reconstruction by replacement of chordae tendineae, leaflet excision, and suture annuloplasty without an annular ring. Postoperatively, left ventricular outflow tract obstruction developed and echocardiography revealed systolic anterior motion of the mitral valve. These findings disappeared after medication with a beta-blocking drug.
