Mitral regurgitation (MR) is the most common valvular heart disease, however, majority of patients are not suitable for open heart surgery due to comorbidity such as organ and heart dysfunction. Transcatheter edge-to-edge mitral valve repair has become an effective treatment option for high-risk patients with MR. Two patients were enrolled in this study inlcuding one 60-year degenerative mitral regurgitation patient and one 72-year functional mitral regurgitation patient. Transcatheter repair procedure was successfully done for the two patients without postoperative complication.
Mitral regurgitation has high morbidity and mortality. The application of transcatheter edge-to-edge mitral valve repair (TEER) has provided more options for the management of primary and secondary mitral regurgitation. With the accumulation of operator experience, the improvement of equipment, and the optimization of intraoperative imaging, TEER can be applied to more complex or critically ill patients. The incidence of TEER-related adverse events is low, but some complications that may occur are potentially dangerous. TEER-related complications and their treatment methods are the guarantee of safe and effective operation. This article discusses the main possible complications of TEER and the corresponding management strategies.
