CHoice of OptImal transCatheter trEatment for Mitral Insufficiency Registry

This multinational, investigator-initiated registry aims to investigate clinical outcomes of patients undergoing transcatheter mitral valve replacement (TMVR). The registry primarily focuses on patients treated with TMVR in real-world clinical practice. Patients evaluated for TMVR but not undergoing the procedure are no longer systematically included. Historical data may include such patients who subsequently underwent alternative treatments, including transcatheter edge-to-edge repair, mitral valve surgery, or medical/conservative therapy.
