Anomalous origin of the right coronary artery with severe stenosis of the left coronary artery orifice: a case study.

BACKGROUND

Anomalous aortic origin of the coronary artery (AAOCA) represents a form of congenital heart disease. Several primary types of anomalous origin of the coronary artery (AOCA) exist. Patients with certain AOCA types may be at risk of sudden cardiac death (SCD) if timely intervention is delayed.

CASE DESCRIPTION: This study reports a case of an 11-year-old female pediatric patient who experienced multiple episodes of syncope before being evaluated at our hospital. She was diagnosed with an anomalous origin of the right coronary artery from the left coronary sinus, along with severe stenosis at the left coronary artery orifice, following transthoracic echocardiography (TTE) and other detailed examinations. The patient subsequently responded well to surgical unroofing for AAOCA combined with single internal mammary artery-coronary artery bypass grafting.

CONCLUSION

As advancements in ultrasonic medicine progress, TTE has proven to be a valuable non-invasive method for diagnosing AAOCA. In this paper, the findings from echocardiography, computed tomography angiography (CTA), and ascending aortography of the patient were analyzed retrospectively to explore the diagnostic value of echocardiography for this condition and to enhance its diagnostic efficacy.
