2.6 Residual anatomical malformation
Another serious issue was residual anatomical problems (26.09%, n = 6).
Only one patient who undergone re-operation survived. Three patients
involved residual ventricular septal shunt and residual aortic arch
obstruction, and two cases had postoperative aortic valve insufficiency.
Although several cases weaned successfully, but died finally due to
recurrent heart failure.
