[A single coronary artery exiting the left sinus of Valsalva: 3 different pathways of the right branch]

Area of Science:

• Cardiovascular Medicine
• Anatomical Studies
• Interventional Cardiology

Background:

• Congenital coronary artery anomalies are rare but can have significant clinical implications.
• Variations in coronary artery origins, particularly from the Valsalva sinus, require careful anatomical description.
• Understanding these anomalies is crucial for accurate diagnosis and treatment planning.

Observation:

• Three elderly male patients presented with a unique coronary artery anomaly.
• All patients exhibited a single coronary artery arising from the left Valsalva sinus.
• Two patients demonstrated an aberrant course of the right coronary artery.

Findings:

• Detailed anatomical and angiographic findings are presented for each case.
• The right coronary artery originated from the left Valsalva sinus and followed varied pathways.
• Specific origins for the right branch included the left anterior descending, left main, and circumflex arteries.

Implications:

• This report contributes to the understanding of rare coronary artery anomalies.
• Accurate anatomical delineation is essential for preventing misdiagnosis and guiding interventions.
• Knowledge of these variations aids in risk stratification and management of affected individuals.
