Midterm outcome after surgical correction of an anomaly of the left coronary artery from the pulmonary artery.

OBJECTIVE

This study aims to present the midterm outcomes of surgical correction of the anomalous left coronary artery from the pulmonary artery (ALCAPA).

METHODS

This is a retrospective study of patients undergoing anomalous origin of the LCA from the pulmonary artery repair between 2010 and 2019.

RESULTS

Forty-nine patients (20 boys and 29 girls) underwent ALCAPA repair. Patients were divided into two groups based on their age at ALCAPA repair: infant (< 1 year of age: n = 24) and non-infant ( ≧ 1 year of age: n = 25). Median age at time of repair was 23 months(7-60months). LCA reimplantation was performed in 47 patients, and Takeuchi repair was performed in 2 patients. Hospital mortality in the infant group was 8.2% (4 of 49). Infant group had significantly lower LVEF in pre-operation (p < 0.05), but there was not significantly different between the two groups about LVEF at discharge. The median follow-up duration was 43(18-85)months. The freedom from reoperation was not significantly different between two groups (infants vs. non-infants: 68.8% vs. 87.5% at 10 years; p = 0.096).

CONCLUSIONS

Surgical treatment of ALCAPA had an excellent early and midterm outcomes. Left ventricular dysfunction in pre-operation was the main risk of mortality in-hospital. The freedom from reoperation did not differ significantly between infant group and non-infant group.
