Single left coronary artery and coronary sinus opening anomaly in a patient presenting with cardiac symptoms

Area of Science:

• Cardiology
• Congenital Heart Disease
• Medical Imaging

Background:

• A single left coronary artery is a rare congenital anomaly.
• It is often associated with other congenital cardiac malformations.
• Coronary sinus anomalies are also congenital defects affecting the heart's venous system.

Observation:

• This case report details a patient with both a single left coronary artery and a coronary sinus anomaly.
• Diagnostic imaging modalities used included coronary angiography and multidetector computed-tomography angiography.
• The presence of both anomalies was clearly visualized through these advanced imaging techniques.

Findings:

• The study identified a rare co-occurrence of a single left coronary artery and a coronary sinus anomaly.
• This specific combination of congenital cardiac malformations has not been previously reported in existing literature.
• Both coronary angiography and MDCT angiography were effective in demonstrating this rare anatomical presentation.

Implications:

• This case expands the known spectrum of congenital coronary artery anomalies.
• It highlights the importance of comprehensive imaging in diagnosing complex congenital heart disease.
• Further research may be warranted to understand the embryological basis and clinical significance of this combined anomaly.
