Mitral transcatheter edge-to-edge repair (M-TEER) offers a transformative, less invasive treatment for severe mitral regurgitation in non-surgical candidates, guided by comprehensive imaging.
This review highlights the critical role of comprehensive echocardiographic imaging and careful patient selection for successful outcomes in mitral transcatheter edge-to-edge repair.
Mitral regurgitation (MR) is a common valvular heart disease associated with significant morbidity and mortality. For patients at high or prohibitive surgical risk, mitral transcatheter edge-to-edge repair (M-TEER) offers a less invasive alternative to surgery. This review outlines key aspects of patient selection and procedural planning for M-TEER, with a focus on clinical and echocardiographic criteria essential for success. Comprehensive imaging-especially 2D and 3D transesophageal echocardiography-is critical to assess leaflet anatomy, coaptation geometry, and mitral valve area. Selection criteria differ between primary and secondary MR and are guided by trials such as COAPT and MITRA-FR. Optimal outcomes rely on careful screening, anatomical suitability, and multidisciplinary evaluation. With growing experience and advancing technology, M-TEER has become a transformative option for treating severe MR in non-surgical candidates.
Zygouri et al. (2025) conducted a review in Mitral regurgitation. Mitral transcatheter edge-to-edge repair (M-TEER) was evaluated. Mitral transcatheter edge-to-edge repair (M-TEER) offers a transformative, less invasive treatment for severe mitral regurgitation in non-surgical candidates, guided by comprehensive imaging.
