2.1 Patient profiles
TBV or so called double-outlet right ventricle with subpulmonary VSD, was defined as a heart with double-outlet right ventricle, sub-pulmonary VSD, without pulmonary stenosis, the Ao arises completely and the pulmonary artery (PA) more than 50% from the right ventricle, the great arteries relationship maybe side-by-side or anteroposterior (10). We retrospective all patients diagnosed with TBV between June 2010 and December 2018, who underwent the ASO and VSD closure silmutaneously at National Children’s Hospital, Hanoi, Vietnam. With the exception of our first patient, who underwent staged repair (coarctation repair without PA banding 2 weeks before the ASO), all of the remaining TBV with aortic arch anomalies successfully underwent single-stage total correction.
Exclusion criteria were the TBV patient who underwent ASO with PA banding and staged VSD closure.
