Transcatheter mitral valve replacement (TMVR) with off‐label use of aortic balloon‐expandable transcatheter heart valves has emerged as a therapeutic option in high‐surgical risk patients with severe mitral annular calcification. Left ventricular outflow tract (LVOT) obstruction post valve deployment is a major limitation. We describe a case of septal reduction therapy using radiofrequency ablation (RFA) when established methods of septal reduction were either ineffective or not feasible. RFA permitted successful enlargement of the LVOT area and subsequent TMVR.
