This study aimed to investigate the structure of the mitral valve in patients undergoing mitral valvuloplasty (MVP) using real-time three-dimensional transesophageal echocardiography (RT-3D-TEE). The main objective was to study the relationship between intraoperative annuloplasty ring size and mitral valve structure dimensions, with a focus on exploring the application value of RT-3D-TEE in MVP.
