Abstract:
Intracardiac repair for cardiac anomalies associated with a transposed aorta from the right ventricle is a technically demanding operation. We present two cases of left ventricular outflow tract (LVOT) obstruction after the use of an ePTFE flat patch to reconstruct the LVOT. Case 1 : A 10-year-old boy had undergone the Rastelli operation, VSD enlargement, and intraventricular re-routing using an ePTFE flat patch for repair of the DORV with noncommitted VSD and pulmonary stenosis at the age of 5. Five years later, catheter examination revealed severe LVOT obstruction. Intraventricular re-routing using a part of the ePTFE graft concomitant with re-replacement of an extracardiac conduit was successfully performed. Case 2 : A 13-year-old girl had undergone a double-switch operation (Senning operation, the Rastelli operation, and intraventricular re-routing by the use of an ePTFE flat patch) for the repair of corrected TGA, PA and VSD at the age of 7. Six years later, catheter examination revealed severe LVOT obstruction. Intraventricular re-routing using part of the ePTFE graft concomitant with re-replacement of an extracardiac conduit was successfully performed. We consider that the use of a flat patch for reconstruction of a left ventricular out flow tract in cases with transposition of the aorta from the right ventricle involves a risk of future development of LVOT obstruction.
