An extremely rare coronary artery variant, an anomalous connection between the sinus node artery and A-V node artery, was found in an adult. This report reviews coronary embryogenesis and normal nodal arterial blood supply.

Area of Science:

  • Cardiovascular anatomy
  • Coronary artery variants
  • Nodal artery supply

Background:

  • Understanding the normal arterial supply to the heart's nodes is crucial for cardiac electrophysiology.
  • Coronary artery anomalies are rare but can have significant clinical implications.
  • The sinus node artery and A-V node artery typically arise independently.

Observation:

  • A case report details an adult diagnosed with an anomalous connection between the sinus node artery and the A-V node artery.
  • Angiographic data confirmed this rare coronary variant.
  • Clinical data from the patient were also analyzed.

Findings:

  • The study identified and described an extremely rare coronary variant involving the sinus node artery and A-V node artery.

  • This finding contributes to the understanding of coronary embryogenesis and variations in nodal arterial supply.
  • The specific anatomical connection observed is highly unusual.

    • Implications:

    • This case highlights the importance of recognizing rare coronary anomalies during diagnostic procedures.
    • Further research into the embryological basis of such variants may provide insights into congenital heart development.
    • Understanding these variations is essential for accurate interpretation of cardiac imaging and electrophysiological studies.
