Abstract:
Mitral regurgitation (MR) is the most common heart valve disease, and transcatheter edge-to-edge repair (TEER) has been recommended as a therapy for severe MR patients by guidelines. The classic Carpentier classification used to guide surgical mitral valve repair but is inadequate for mitral TEER (M-TEER). We herein proposed a new modified Carpentier classification named after "type + segment," which is suitable for M-TEER. We shared our strategies in M-TEER procedure for screening and performing the M-TEER according to the new modified Carpentier classification.
