[Congenital aortic regurgitation complicated by infective endocarditis of tricuspid valve due to spontaneous closure of ventricular septal defect: a case report].
A 32-year-old woman presented with a rare case of tricuspid valve endocarditis causing inflammatory reopening of the spontaneously closed ventricular septal defect (VSD), associated with aortic valve malformation. She was admitted to our hospital because of fever lasting 4 weeks. Severe aortic regurgitation was revealed by color Doppler echocardiography. Blood culture identified Microccus faecalis. Antibiotics were administered over 3 weeks, but serial echocardiography showed a developing vegetation in the right ventricle and left-to-right shunt flow. The diagnosis was infective endocarditis complicated by aortic ring abscess and interventricular septal fistula. Surgery performed on the 22nd hospitalized day found a vegetation of the tricuspid valve, a membranous type of VSD, and aortic valve malformation. Aortic valve replacement, patch closure of VSD, and tricuspid valvuloplasty achieved a successful outcome.
