Transcatheter mitral valve edge-to-edge repair (TEER) has become an important treatment opinion for patients with severe mitral regurgitation (MR) at high risk for surgery. The devices and procedural techniques of TEER are complex and require excellent team cooperation. However, there is still a lack of standardized clinical pathways in China. Based on the latest evidence, the expert group wrote this clinical pathway to guide and optimize TEER therapy in clinical practice. It demonstrates the following key issues of clinical concern: (1) TEER team building; (2) preoperative clinical evaluation of TEER patients; (3) imaging assessment before TEER procedure; (4) standardized procedures for TEER; (5) TEER for complex MR; (6) the standard process of perioperative comprehensive management; and (7) full life-cycle rehabilitation and follow-up. This clinical pathway might be helpful to facilitate the standardized development of TEER therapy and application, and promote the improvement of management and life quality for patients with MR.
Transcatheter mitral valve edge-to-edge repair (TEER) has become an essential treatment option for patients with severe mitral regurgitation at high or prohibitive surgical risk. However, the surgical devices and procedural steps of the surgery are intricate, and there is currently a lack of standardized TEER procedures in China. Based on existing evidence and the accumulated experience in clinical practice, this article briefly introduces the definition, indications, contraindications, and surgical devices of TEER. It also provides a systematic and detailed elaboration on the procedural steps, key technical points, complications, and their management measures, offering guidance for the standardized implementation and widespread adoption of TEER in clinical practice in China.
