Predictors of optimal procedural result after transcatheter edge-to-edge mitral valve repair in secondary mitral regurgitation

Background Procedural success after transcatheter edge-to-edge mitral valve repair (TEER) is defined as a reduction of mitral regurgitation (MR) degree to = 20 procedures/year were independent predictors of the optimal procedural result. Compared to patients with acceptable procedural result, those with optimal result had shorter device time and length of stay and better outcomes with lower rates of all-cause and cardiac deaths (25.7% vs. 40%, p < 0.001 and 16.3% vs. 24.8%, p = 0.003, respectively) and HF hospitalizations (24% vs. 30%; p = 0.035) at 2-year follow-up. Conclusions In patients with secondary MR undergoing TEER, an optimal procedural result is associated with favorable outcomes and can be achieved by selecting patients with moderate-to-severe MR, without severe left ventricular dilatation, and treated in high-volume centers.
