Résumé
Left ventricular outflow tract obstruction may occur following transcatheter mitral valve replacement in the setting of mitral annular calcification. We present a case series whereby preemptive septal radiofrequency ablation (RADIO-TMVR) was used to augment the left ventricular outflow tract for transcatheter mitral valve replacement in 4 patients at risk for left ventricular outflow tract obstruction despite alcohol septal ablation. All patients were female, average age of 74.9 (68.8-80.4) years. Baseline ejection fraction was 71% (63%-75%). Mean mitral valve area was 1.28 (range, 1.0-1.59) cm In at-risk individuals, preemptive septal radiofrequency ablation may be an effective strategy at preventing left ventricular outflow tract obstruction with transcatheter mitral valve replacement.

BACKGROUND
Left ventricular outflow tract obstruction may occur following transcatheter mitral valve replacement in the setting of mitral annular calcification.
METHODS
We present a case series whereby preemptive septal radiofrequency ablation (RADIO-TMVR) was used to augment the left ventricular outflow tract for transcatheter mitral valve replacement in 4 patients at risk for left ventricular outflow tract obstruction despite alcohol septal ablation.
RESULTS
All patients were female, average age of 74.9 (68.8-80.4) years. Baseline ejection fraction was 71% (63%-75%). Mean mitral valve area was 1.28 (range, 1.0-1.59) cm
CONCLUSIONS
In at-risk individuals, preemptive septal radiofrequency ablation may be an effective strategy at preventing left ventricular outflow tract obstruction with transcatheter mitral valve replacement.
