Advanced Echocardiography Assessment in the Management of Alcapa Syndrome: Case Report

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare and potentially life-threatening condition affecting infants that requires immediate corrective surgery to restore blood flow to the myocardium. We present a case of an infant with ALCAPA and severe heart failure. What sets this case apart is the utilization of speckle-tracking echocardiography as a non-invasive method for assessing global and regional myocardial function before and after surgical intervention. Our preoperative analysis revealed compromised contraction in specific areas of the left ventricle (LV), in the regions that were supplied by both the left coronary artery (LCA) and the right coronary artery (RCA). Interestingly, despite an increase in ejection fraction (EF) measured by conventional echocardiography, the postoperative speckle-tracking analysis revealed persistent impairment in the anterior territories supplied by LCA, highlighting the potential of this technique in identifying myocardial abnormalities during postoperative follow-up. In conclusion, speckle-tracking echocardiography may be a valuable tool for identifying subtle myocardial changes in ALCAPA patients with a higher sensitivity in detecting regional left ventricular (LV) dysfunction compared to conventional echocardiography.
