Popis: | Background The most common complication of Transcathether Aortic Valve Replacement (TAVR) is aortic regurgitation (AR). Typically, this regurgitation is in the mild range, yet in a smaller subset AR could be in the moderate-severe range. Significant regurgitation is usually due to paravalvular leak due to undersizing of the valve or malposition inferiorly into the left ventricular outflow tract or superiorly into the aorta during deployment. Transthoracic Echocardiography (TTE) is first line test for the amount of regurgitation, but can be flawed due to poor acoustic windows and eccentricity of the paravalvular leak. Cardiac MRI (CMR) may be used to assess the aortic regurgitation when there is a discrepancy with echocardiography or imaging of the valve is in question. |
