ultrasonic cardiography (UCG)
Trans-thoracic echocardiography (TTE) is performed in the resting position. Trans-esophageal echocardiography (TEE) is performed under surface anaesthesia with bupivacaine or intravenous anaesthesia. We comprehensively assess the severity of mitral regurgitation according to American Society of Echocardiography (ASE) guideline.
TEER
Two commercial cliping systems are available for clinical use: the G3 MitraclipTM and the G4 MitraclipTM (Abbott), DragonflyTM (Dejin), which will be introduced to the Chinese market in 2024, with the specific choice determined by the operator. The patient receives general anaesthesia (intravenous and endotracheal). The operator performs the procedure according to the recommended surgical steps in the product manual, guided by X-ray and trans-esophageal echocardiography. Postoperative MR ≤2+ is considered successful, and if the result is unsatisfactory, 1-2 additional clips are given.
