Key result
In neonates undergoing arterial switch operation, coronary patterns with intramural arteries were associated with higher mortality (28%) compared to other coronary patterns (3.9%).
Why the study?
Does the presence of intramural coronary arteries worsen outcomes in neonates undergoing arterial switch operation for transposition of the great arteries?

May inform preoperative risk stratification in transposition; leaves open whether modified techniques reduce mortality in intramural cases.

Does the presence of intramural coronary arteries worsen outcomes in neonates undergoing arterial switch operation for transposition of the great arteries?
Absolute Event Rate: 28% vs 3.9%
Coronary patterns with intramural arteries remain associated with high coronary mortality and morbidity following neonatal arterial switch operation.
Metton et al. (2010) conducted a cohort in Transposition of the great arteries (TGA) (n=919). Coronary patterns with intramural arteries vs. Other coronary patterns was evaluated on Mortality. In neonates undergoing arterial switch operation, coronary patterns with intramural arteries were associated with higher mortality (28%) compared to other coronary patterns (3.9%).
