Abstract

There are multiple surgical approaches described to repair the left pulmonary artery (LPA). Regardless of the technique used, rate of restenosis is very high. We describe a case of discontinuous LPA which was treated by turning down the entire autologous main pulmonary artery (MPA) and creating a direct anastomosis between the MPA and LPA. This was in background of tricuspid and pulmonary atresia, hypoplastic right ventricle with atrial and ventricular septal defects and ductus arteriosus feeding the left pulmonary artery. This new technique resulted in a tension free tissue-tissue anastomosis with potential for growth and produced hemodynamically gratifying short-term results.
