What is The Influence of Coronary Artery Anatomy on Mortality After the Arterial Switch Operation about?

## Objective: We sought to determine the influence of coronary artery anatomy on mortality in more than 1000 children undergoing the arterial switch operation. ## Methods: All patients who underwent an arterial switch operation were identified from 2 hospital databases and reviewed retrospectively. coronary anatomy was recorded from operative reports using the leiden classification. ## Results: An arterial switch operation was performed in 1033 children between 1983 and 2013. coronary anatomy was normal in 697 patients (67%). the most common type of anomalous coronary anatomy was the circumflex coronary artery arising from sinus 2 (in 152 patients [15%]). forty-seven patients (4.5%) had all coronary arteries arising from a single sinus. of these 47 patients, 34 patients (3.3%) had a true single coronary artery. fifty-two patients (5.0%) had an intramural coronary artery. overall early mortality was 3.3% (34 out of 1033 patients) over the 30-year period. early mortality was 3.0% (21 out of 697) for patients with normal coronary anatomy and 3.9% (13 out of 336) for any type of anomalous coronary anatomy. early mortality was 3.3% (5 out of 152) for patients with the circumflex coronar
