Successful report of taussig-bing malformation treated by anterior intraventricular tunnel repair / 日本心臓血管外科学会雑誌

ABSTRACT

A 13-month-old girl (BW 4476g) with Taussig-Bing malformation was successfully treated by anterior intraventricular tunnel repair (Patrick-McGoon method). She had large subpulmonary malalignment ventricular septal defect with extreme inflow extension with anteroposterior relationship of the great arteries. Coronary arterial anatomy was a very rare type in that LAD branching from RCA originated from right facing sinus was running just anterior to the aorta and coronary relocation would result in straining and obstructing LAD. Intraventricular tunnel through the VSD to the aorta was tailored by use of a double velour Dacron conduit (14mm in diameter) and inflow extension of VSD was partly closed with a separate flat Dacron patch. LVOTO was not found on echocardiography and good clinical results were obtained at 11 months postoperatively.
