This paper reports the nursing care of an elderly patient with posterior mitral valve prolapse and severe mitral regurgitation underwent "minimally invasive transcatheter mitral valve repair via femoral vein" guided by digital subtraction angiography (DSA). The nursing focus includes instrument and articles preparation, position and pipeline management, vital signs observation, important indicators monitoring, operation coordination, temperature management and patient psychological care. The elderly patient was transferred to ICU 3 hours and 47 minutes after operation, and was transferred to the general ward 2 days later, and was discharged successfully 7 days after operation. Transcatheter mitral valve repair is one of the effective measures for the treatment of mitral insufficiency/mitral regurgitation. Good perioperative nursing care is an important factor for the smooth operation and quality assurance.
