A Case of Systolic Anterior Motion After Mitral Valve Repair Causing Hemolytic Anemia: Mechanism and Treatment

Can J Cardiol. 2020 Dec;36(12):1977.e5-1977.e8. doi: 10.1016/j.cjca.2020.07.008. Epub 2020 Jul 17.

Abstract

Hemolytic anemia after mitral valve repair and ring annuloplasty is uncommon when compared with mitral valve replacement. In this report we present the case of a 67-year-old woman who had undergone mitral valve repair with a Duran band and developed hemolytic anemia. Most patients with severe hemolysis after mitral valve repair undergo reoperation. However, in the present case, the hemolysis was found to be secondary to systolic anterior motion of the mitral valve and left ventricular outflow tract obstruction and was treated without the need for reoperation.
