Identifies a novel 'small orifice regurgitation increasing' (SORI) phenomenon during TEER for commissural MR, which may help understand and prevent residual MR.
Transcatheter edge-to-edge repair (TEER) has emerged as a prominent therapeutic approach for mitral regurgitation (MR) in recent years. For commissural, a higher grade of MR would be detected post-TEER compared to it during the procedure, while the mechanism hasn't been elucidated yet. Two patients with commissural MR underwent TEER at our center. Through these cases, we identifies and names a novel phenomenon ("small orifice regurgitation increasing" "SORI") in TEER procedures, providing key insights to better understand and prevent residual commissural MR.
