Aortic Valve Endocarditis with Anomalous Origin of the Right Coronary Artery and Unknown Infected Thrombus in the Dissected Descending Thoracic Aorta.

We report an intricate aortic root replacement in a young male patient suffering from native valve infective endocarditis due to Serratia marcescens. Further complicating the total root replacement, there was an unknown infected aortic thrombus and a concomitant anomalous right coronary artery with an intramural course. As a result of our more aggressive approach, we believe that we lowered the risk of recurrent infection of the bioprosthesis of the aortic root.
