Transcatheter mitral valve replacement (TMVR) is an emerging treatment of mitral valve pathology in patients that are not candidates for conventional surgical approaches. Higher rates of left ventricular outflow tract obstruction (LVOTO) may occur following TMVR and its occurrence is an independent predictor of mortality. We present a case of severe mitral stenosis and annular calcification that was treated with a balloon‐expandable Sapien S3 valve in the mitral position delivered through surgical port‐access approach, which resulted in postoperative LVOTO. The LVOTO was successfully treated with alcohol septal ablation with immediate reduction in outflow tract gradients and long‐term resolution.
