[A case report: right ventricular outflow tract (RVOT) reconstruction using homograft for RVOT restenosis after Jatene's procedure of transposition of the great arteries (TGA)].
A 7-year-old boy was admitted for RVOT restenosis. The patient was born following an unremarkable pregnancy and delivery. He was carried out Jatene's procedure for TGA at 23rd day after birth. At 19 month of age, he was removed pulmonary stenosis using patch angioplasty with mono cusp. When he was 6 year of age, the onset of edem, ascites and hepatomegaly were pointed out. At 7 year of age, he was admitted for edema, hypoproteinemia and protein loosing enteropatchy. After he was treated medical therapy, cardiac catheterization showed markedly right atrial and right ventricular hypertension and ventricular septal defect (VSD). Cine angiography suggested the right ventricular outflow tract stenosis, pulmonary valve and tricuspid valve insufficiency. On August 1, 1996, the patient underwent surgical repair: direct closure of VSD, aortic homograft (20mm) replacement for RVOT stenosis and tricuspid valve annuloplasty by DeVega's procedure. Postoperative course was uneventful. At 23rd postoperative day, cardiac catheterization and cine angiography showed no problems. He was not treated with anticoagulation.
