Transesophageal echocardiogram; A. Transgastric view shows the right ventricular lead (arrows) without evidence of thrombus or vegetation. B. Mid-esophageal view shows the right atrial lead (arrows) towards the right atrial appendage without evidence of thrombus or vegetation (Video S1). C. High esophageal view depicts the superior vena cava (SVC) in long axis and within it there is a visible lead (white arrow), and deep in the SVC an elongated mobile echogenic mass (thrombus or vegetation, yellow arrow) moving with the SVC venous flow (Video S2), attached to one of the leads. RA=Right atrium; RV=right ventricle.

She underwent a TEE which a showed mobile mixed echogenicity of 1.4 x 0.5 cm attached to the RA lead consistent with thrombus versus vegetation (Fig. 1).
18FDG PET/CT showed circular uptake involving the TAVR within normal limits and favored to be reactive.

There was circular uptake involving the TAVR that appeared within physiologic limits and favored to be reactive (Fig. 2).
