Outcomes of the arterial switch operation in patients with inverted coronary artery anatomy

Abstract

Objective: Patients undergoing the arterial switch operation (ASO) with inverted coronary anatomy represent a technical challenge. We sought to determine the long-term outcomes of patients with inverted coronary anatomy who underwent an ASO. Methods: A retrospective analysis of patients who underwent an ASO with inverted coronary anatomy at a single institution was performed and comparison was made between patients with inverted and normal coronary anatomy. Results: There were 43 (5.1% [43 out of 844]) patients with inverted coronary anatomy. Twenty patients (46.5% [20 out of 43]) had a right coronary artery that arises from sinus 1 and the left anterior descending and circumflex coronaries ..
