Key result
Following the arterial switch operation, 28.66% of patients developed mild, 5.07% moderate, and 5.31% severe pulmonary stenosis, with 21 requiring interventions and 9 requiring reoperation.
Why the study?
Pulmonary stenosis is a common multifactorial complication following the arterial switch operation, prompting an evaluation of its post-operative frequency, related reinterventions and reoperations, and potential risk factors.
Population
848 patients undergoing arterial switch operations for transposition of the great arteries between 1991 and 2020
Design
Single-center retrospective cohort study

Highlights need for long-term monitoring after arterial switch; extends observational data on stenosis incidence but leaves practice implications open.

Pulmonary stenosis is a common complication following the arterial switch operation for transposition of the great arteries, with patch reconstruction and aortic arch anomalies significantly increasing the risk of subsequent reinterventions.
Sobczak-Budlewska et al. (2022) conducted a cohort in Transposition of the great arteries (n=848). Arterial switch operation was evaluated on Frequency of pulmonary stenosis, reinterventions, and reoperations during post-operative follow-up. Following the arterial switch operation, 28.66% of patients developed mild, 5.07% moderate, and 5.31% severe pulmonary stenosis, with 21 requiring interventions and 9 requiring reoperation.
