Abstract:
Assessing aortic regurgitation (AR) severity in patients with mitral valve prosthesis may pose an echocardiographic challenge. We present a case of mild AR in whom difficulty occurred in judging its severity due to eccentric mitral prosthetic inflow signals filling practically completely the proximal left ventricular outflow tract in diastole mimicking severe AR. Frame-by-frame analysis of two-dimensional transthoracic echocardiographic images using a small sector depth and width was helpful in clarifying the true severity of AR.
