Case Report: Favoring biventricular repair beyond the conventional boundaries with primary arterial switch operation in a young adult [version 1; peer review: 2 approved with reservations]

Transposition of great arteries (TGA) presents in neonates or in infancy. We report a case of TGA with ventricular septal defect (VSD) and pulmonary stenosis (PS) in an adult male patient of 23 years age. Arterial switch operation with VSD closure and neo-aortic valve replacement was done. The patient recovered well in the post-operative period. In adult patients, conversion from atrial to arterial switch has been widely reported, both directly and after prior pulmonary artery banding in two stages, but primary arterial switch for TGA has not been reported previously. In this patient there was a benefit of having a large VSD and severe PS.
