Suggests feasibility of balloon inflation plus alcohol septal ablation for acute LVOTO post-TMVR; leaves open generalizability.
Balloon inflation in the LVOT and alcohol septal ablation can successfully manage life-threatening acute LVOT obstruction following transcatheter mitral valve replacement in patients with mitral annular calcification.
