文摘

Three-dimensional echocardiography in patients with AS shows a funnel-shaped morphology of the LVOT in >80% of patients. The size and circularity of the LVOT differ significantly on the basis of the point of measurement. More than 70% of patients have ellipse-shaped LVOTs at the HP of the aortic cusps. The best correlation between 2D TTE and 3D TEE dimensions is obtained when measurement occurs close to the annular plane.
