From: Imaging of the aortic root on high-pitch non-gated and ECG-gated CT: awareness is the key!
A 67-year-old female status transcatheter aortic valve replacement (TAVR) using Sapiens valve (Edwards Lifesciences) with suspected aortic valve lesion on echocardiogram. Axial (a) and coronal oblique (b) reconstructed CTA images reveal biconvex hypoattenuating (Hounsfield unit, 74) leaflet and left cusp thickening causing restricted motion (seen on cine), consistent with thrombus
