Fig. 3. Four years after surgical aortic valve replacement, a 49-year-old woman developed dyspnea. (A) On an aortic valve in-plane view, subvalvular tissue ingrowth (arrows) below the prosthetic aortic valve is noted. (B) A sagittal image of the left ventricular outflow tract shows the lesion in the subvalvular area (arrows). The lesion is showing 160–220 Hounsfield units on computed tomography, suggesting pannus formation. Transvalvular peak velocity (3.4 m/s) and pressure gradient (45/25 mm Hg) were high on echocardiography. AO: ascending aorta, LA: left atrium, LV: left ventricle, RVOT: right ventricular outflow tract. Fig. 3. Four years after surgical aortic valve replacement, a 49-year-old woman developed dyspnea.
