A single-center retrospective study evaluating cardiac magnetic resonance imaging (CMR) in patients with repaired d-transposition of the great arteries (d-TGA) after arterial switch operation (ASO) found that left ventricular function was preserved in most cases. Among the 52 patients studied, the median left ventricular ejection fraction was 60%, with only 19% showing reduced ejection fraction. The study emphasizes the need for ongoing surveillance as these patients transition into adulthood, highlighting potential risks associated with underlying coronary anatomy and arrhythmias due to fibrosis.
