[Modified extended septoplasty for left ventricular outflow tract obstruction after repair of double-outlet right ventricle report of a case].
A three-year-old boy with residual VSD and LVOTO after repair of double outlet right ventricle underwent modified extended septoplasty successfully. Preoperative left ventriculography showed a residual VSD and LVOTO. The peak systolic pressure gradient between the left ventricle and aorta was 38 mmHg. Operation aimd not only at relief of the obstruction, but also at streamlining of the LVOT by removal of protrusions. We modified the extended septoplasty reported by Belli et al in 1996. The postoperative course was uneventful and patient was discharged at 15 postoperative day. The most recent echocargiogram revealed no residual LVOTO.
