RÉSUMÉ
A 74-year-old man was diagnosed with infective endocarditis (IE) involving the aortic and tricuspid valves, ventricular septal defect (VSD), and complete atrioventricular block. He was admitted to a previous hospital with complaints of fever and neck pain, and he developed complete atrioventricular block during the course of his illness. An echocardiogram revealed severe aortic regurgitation, aortic valve vegetations, and a ventricular septal defect. He was then transferred to our hospital, and he underwent emergent surgery. The aortic valve cusps were calcified and thick, with significant cusp destruction. The vegetations partly extended to the subvalvular area of the right and non-coronary cusp. The vegetations also extended from the atrial septum to the tricuspid valve septal leaflet and perimembranous VSD. Ventricular septal reconstruction using the sandwich technique with two bovine pericardial patches, aortic valve replacement, and tricuspid valve replacement were performed. Postoperatively, he received antibiotic therapy for six weeks and was discharged from our hospital after the implantation of a cardiac resynchronization therapy pacemaker. Echocardiography showed no residual shunts. Our case suggests that the sandwich technique can be a useful method of septal reconstruction for IE with extensive destruction of the ventricular septum.
