Key result
VSD rerouting and arterial switch for DORVncVSD shows ~90% survival with NYHA class I outcomes.
Why the study?
Biventricular repair of DORV with non-committed VSD is usually achieved by VSD rerouting to the aorta, but this technique has limitations related to tricuspid chordae and pulmonary artery-tricuspid valve distance.

Alternative VSD rerouting may mitigate late obstruction risk in DORVncVSD; leaves open need for prospective validation before wider use.
Observational (n=10)
VSD rerouting to the pulmonary artery combined with an arterial switch is a feasible surgical technique for biventricular repair of DORVncVSD, yielding excellent early clinical and hemodynamic outcomes.
Lacour-Gayet et al. (2002) conducted an observational in Double outlet right ventricle non-committed ventricular septal defect (DORVncVSD) (n=10). VSD rerouting to the pulmonary infundibulum and arterial switch was evaluated on Survival. VSD rerouting to the pulmonary artery and arterial switch in 10 patients with DORVncVSD resulted in 9 survivors, all in NYHA class I with no subaortic gradient >15 mm at 20 months.
