A modified Carpentier classification in transcatheter edge‐to‐edge repair for mitral regurgitation

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.
