case_images: CW-measured peak transvalvular gradient 62mmHg and mean transvalvular gradient 41mmHg) with mild regurgitation; mild mitral valve stenosis with mild regurgitation; concentric hypertrophy of left ventricular wall (thickness of posterior wall of left ventricle 13mm); moderate left ventricular outflow tract (LVOT) stenosis (CW-measured peak cross-outflow tract gradient 58mmHg and mean cross-outflow tract gradient 21mmHg); pulmonary artery systolic pressure 36mmHg, left atrial dilatation (end diastolic diameter 47mm), left ventricular end diastolic diameter 43mm, left ventricular ejection fraction 66%. CT angiography (CTA) report (Figure 1): Her aortic valve was tricuspid with thickening leaflet and mildlymoderate calcification which was unevenly distributed and mainly observed in the junction of leaflets.
