Balloon assisted translocation of the mitral anterior leaflet to prevent left ventricular outflow obstruction (BATMAN): A novel technique for patients undergoing transcatheter mitral valve replacement.
Transcatheter mitral valve replacement (TMVR) is an option for patients at high risk for mitral valve replacement or repair via sternotomy or left thoracotomy approach. TMVR carries up to 22% risk of left ventricular outflow tract (LVOT) obstruction. Severe LVOT obstruction can have devastating hemodynamic and clinical consequences. ⋯ The balloon assisted translocation of the mitral anterior leaflet to prevent left ventricular outflow obstruction technique described here may offer the option of transcatheter mitral valve implantation in patients at high risk of LVOT obstruction. A variation of this technique to allow application in cases with transseptal approach is under investigation.

Multicenter Study Comparative StudyGender-related differences in patients undergoing transcatheter mitral valve interventions in clinical practice: 1-year results from the German TRAMI registry.
Information on gender-related differences in terms of baseline characteristics and clinical outcome of patients undergoing MitraClip® implantation in daily clinical practice have been studied in smaller populations previously. This study sought to additionally evaluate gender-related differences in a larger German real-world patient population. ⋯ In this analysis from a large prospective, multicenter real-world registry MitraClip® implantation is safe and effective for treatment of significant mitral regurgitation with equal postprocedural results and mortality rates during 1-year follow-up. Men and women showed a persisting and significant clinical benefit at 1-year FU after treatment. Complication and re-intervention rates were low. Additional studies are needed to further evaluate our findings on increased bleeding complications and decreased functional improvement in women at 1-year follow-up after MitraClip® therapy.
