Preclinical Validation of Automatic Mitral Valve Segmentation and Measurement Technology for Planning Transcatheter Edge-to-edge Valve Repair Using Computed Tomography

Michael Huy Cuong Pham, Klaus Fuglsang Kofoed, James V. Chapman, Ole de Backer, Jesper J. Linde, Lars V. Køber, Gakuto Aoyama, Keitaro Kawashima and Takuya Sakaguchi Mitral regurgitation (MR) is one of the most common valvular heart diseases, though many patients with severe MR are unsuitable for surgical interventions. Transcatheter edge-to-edge repair (TEER) is an established non-surgical procedure that allows safe and effective reduction of MR in highrisk patients. Appropriate patient selection is critical and achieved through clinical assessment and imaging derived measurement of the mitral valve (MV) apparatus to optimize procedural success.
