Outcome of surgical repair of anomalous left coronary artery from the pulmonary artery in a single-center experience

This study aims to review the midterm results of surgical repair of anomalous left coronary artery from the pulmonary artery (ALCAPA) in our center and assess the postoperative cardiac function recovery and misdiagnosis. Patients who underwent repair of ALCAPA between January 2005 and January 2022 at our hospital were retrospectively reviewed. A total of 136 patients underwent repair of ALCAPA, among which 49.3% were misdiagnosed before referral to our hospital. On multivariable logistic regression analysis, patients with low left ventricular ejection fraction (LVEF) (odds ratio = 0.975, p = 0.018) were at increased risk for misdiagnosis. The median age at surgery was 0.83 years (range, 0.08 to 56 years), and the median LVEF was 52% (range, 5% to 86%). The mortality rate was 6.6% (n = 9), and four patients underwent reintervention. The median postoperative recovery time of left ventricular function (LVF) was 10 days (1 to 692 days). Competing risk analysis revealed that a low preoperative LVEF (hazard ratio = 1.067, p
