This article reports a patient diagnosed with severe aortic stenosis. After admission, the cardiac multidisciplinary team performed transcatheter aortic valve replacement (TAVR) emergently due to its unstable hemodynamics. The procedure was successful, and the initial cardiogram during the operation after TAVR suggested that the stenosis was greatly improved. But gradually the next day bedside echocardiography suggested that the transvalvular pressure difference increased and the prosthetic valve forward blood flow accelerated. Acute valve thrombosis after TAVR was taken into consideration. Warfarin and heparin were administrated for anticoagulation, after which the pressure difference across the valve and the forward blood flow rate of the artificial valve were evenly improved.
