Transcatheter Edge to Edge Mitral Valve Repair for Mitral Regurgitation in Hypertrophic Cardiomyopathy: A Case Series

Mitral valve transcatheter edge-to-edge repair (TEER) is safe and beneficial in patients with severe mitral regurgitation (MR). Recently, TEER has been suggested as an alternative to surgery in patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM) and severe MR who are at high risk for septal reduction surgery.1-4 We present 5 HOCM patients who underwent TEER. MR severity decreased to mild in all patients, and left ventricular outflow tract maximal gradient decreased from 140 ± 46 to 8 ± 5 mm Hg immediately after TEER, and to 41 ± 32 mm Hg at 4 ± 2 months' follow-up.
