TMVR carries up to 22% risk of left ventricular outflow tract (LVOT) obstruction. Severe LVOT obstruction can have devastating hemodynamic and clinical consequences.<\/jats:p><\/jats:sec><jats:sec><jats:title>Hypothesis<\/jats:title><jats:p>We previously presented a novel technique to prevent LVOT obstruction during transapical retrograde mitral valve replacement, by penetrating and ballooning the anterior mitral leaflet (AML), resulting in creation of a \u201chole\u201d and posterior translocation of AML, then deploying the valve.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Three patients underwent TMVR at Saint Louis University for severe mitral regurgitation after being deemed too high risk for surgery, and not candidates for a Mitra\u2010clip procedure. These patients were deemed to be at risk for LVOT obstruction based on the preprocedural evaluation. Via transapical approach, a needle was advanced \u201cthrough,\u201d perforating the AML and wire was placed in the left atrium. Over the wire, an 20\u2010mm valvuloplasty balloon was positioned \u201cwithin\u201d the anterior leaflet and inflated leading to translocation of the AMVL. Then the valve was deployed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>This novel technique has been performed on three patients at our institution. Sapien S3 transcatheter valves were used in all three patients, with 100% procedural success rate.
