Colour Doppler echocardiography showed that the leaflet prolapsed with severe regurgitation, and the regurgitant jet tended to blow rightward within the left atrium. With the assistance of mechanical ventilation and venoarterial extracorporeal membrane oxygenation, the patient underwent mitral valve replacement. UPO is easily misdiagnosed, which leads to delays in treatment. Therefore, accurate diagnosis and immediate treatment are crucial. ER -
