This video clip shows transthoracic echocardiography. The leaflets of the tissue prosthetic valve move well but the orifice area assessed carefully at the tip measures 0.95–1.0 cm2 suggestive of significant stenosis. Peak and mean pressure gradients measured by Doppler are also high at 49 and 32 mm Hg, respectively. This is most likely related to a small size prosthetic aortic valve. (AVR: Aortic valve replacement; LA: Left atrium; LV: Left ventricle; RA: Right atrium; RV: Right ventricle).
