Transcatheter aortic valve replacement (TAVR) is an increasingly common procedure for the treatment of aortic stenosis in elderly patients with comorbidities that prevent the use of standard surgery. It has been shown that implantation without aortic regurgitation is related to lower mortality. Mild paravalvular regurgitation is inevitable in some cases due to calcification of the aortic annulus and its usually somewhat elliptical shape. Central regurgitation is less common, but has been associated with valve overdilatation in cases in which reduction of paravalvular regurgitation was attempted after the initial inflation. However, there are no reported cases of central prosthetic aortic regurgitation due to acute LV dysfunction. We report a case in which central aortic regurgitation occurred due to transient ventricular dysfunction secondary to occlusion of the right coronary artery by an embolus. The regurgitation disappeared after thrombus aspiration and normal ventricular function was immediately recovered.
