Paravalvular regurgitation (PVR) after transcatheter aortic valve replacement (TAVR) is one of the major complications with negative clinical prognosis. Therefore, its prediction is important for further improvement of the outcome. We present a case with TAVR, in which we successfully evaluated aortic valve calcification protruding inward and into the left ventricular outflow tract by real time three-dimensional transesophageal echocardiography, and predicted significant PVR after the procedure. In conclusion, device landing zone calcification protruding inward is a key for the prediction of significant PVR after TAVR.
