ABSTRACT
A 37-year-old male with Ebstein’s anomaly was admitted due to clinical signs of right ventricle dysfunction. The patient had five prior sternotomies due to bioprostheses insertion at the site of the tricuspid position. Echo showed normal left ventricular function and significantly dilated right ventricle, with severe bioprosthesis regurgitation and its concomitant stenosis. The dual-source 384-row computed tomography (CT, SOMATOM® Force, Siemens Healthineers, Erlangen, Germany) allowed for a unique insight into anatomy and mechanism of bioprosthesis failure. Eventually, the patient underwent successful implantation of a balloon-expandable transcatheter heart valve using 29-mm Edwards SAPIEN 3 bioprosthesis (Edwards Lifesciences Irvine, Calif) with overfilling of the deployment balloon (+3 ml).
