Long-Term Outcome Following Prenatal Diagnosis of Transposition of the Great Arteries.

ABSTRACT: Outcomes following the arterial switch operation (ASO) are well documented. Survival and long-term morbidity for fetuses diagnosed with dextro-transposition of the great arteries (d-TGA) are less reported. We aimed to document survival, reinterventions and morbidity for prenatally diagnosed d-TGA to inform prenatal counseling. Fetuses with d-TGA with or without ventricular septal defect (VSD) diagnosed between 1995 and 2022 at our institution were reviewed. Outcomes were compared to postnatally diagnosed patients undergoing intervention during the same era. Two hundred and seven fetuses were diagnosed resulting in 201 livebirths, 2 intrauterine demise, and 4 pregnancy terminations. There were 137 (68.2%) with isolated d-TGA and 64 (31.8%) with d-TGA-VSD. Median birthweight 3.21 kg (IQR 2.9
