The Anatomical History of a Single Coronary Artery Anomaly: A Case Report

Area of Science:

• Cardiology
• Congenital Heart Disease
• Medical Imaging

Background:

• Single coronary artery (SCA) anomaly is a rare congenital condition where the right and left coronary arteries arise from a single ostium.
• While often asymptomatic, SCA can lead to severe cardiac events including myocardial infarction and sudden cardiac death.
• Accurate diagnosis is vital due to potential associations with other congenital anomalies and risks in young individuals.

Observation:

• This report details a case of SCA anomaly identified during emergency conventional angiography.
• The anomaly involved the right coronary artery (RCA) arising from the left main coronary artery (LMCA).
• Both coronary arteries originated from a single ostium within the aorta.

Findings:

• The patient presented with a rare anatomical variation of the coronary arteries.
• Conventional angiography confirmed the origin of both RCA and LMCA from a single coronary ostium.
• This finding highlights the importance of detailed coronary imaging.

Implications:

• Diagnosis of SCA anomaly is critical for risk stratification and management, particularly to prevent sudden cardiac death.
• Understanding the specific anatomical variations of SCA is essential for guiding interventional procedures.
• This case underscores the value of diagnostic angiography in identifying rare cardiac anomalies.
