Coronary artery injury by a valved external conduit.
A 4-month-old infant underwent repair of type I truncus arteriosus and died immediately after as a consequence of left main coronary artery compression by the metallic stent in the Dacron conduit. To avoid injury to the coronary vasculature, the future location of the porcine valve ring should be assessed and relocated if necessary.
