Surgical management of outflow tract obstruction after transapical mitral valve implantation.

Left ventricular outflow tract (LVOT) obstruction due to systolic anterior motion of the anterior mitral valve leaflet (AML) is a known complication after mitral valve repair or transfemoral/transapical mitral valve implantation (TMVI). We present a patient with a previous mitral valve repair who developed LVOT obstruction after TMVI in whom the AML was surgically resected using a transaortic approach.
