Very late transcatheter heart valve thrombosis

Figure 1 Transprosthetic gradients and effective orifice area following transcatheter aortic valve replacement (2 to 54 mo), at the time transcatheter heart valve thrombosis (54 mo) and following anticoagulation therapy (54 to 63 mo). TAVR: Transcatheter aortic valve replacement; THV: Transcatheter heart valve.

Figure 2 Transesophageal echocardiogram. It shows transprosthetic gradients compatible with severe aortic stenosis (A); Absence of obvious mass or valve thrombosis on Transesophageal echocardiogram (B, C) but moderate paravalvular leak (D).
