A rare dual left anterior descending coronary artery anomaly is presented, where one vessel was hypoplastic and the other arose anomalously from the right aortic sinus. This anatomical variation can impact cardiac interventions.

Area of Science:

  • Cardiovascular Medicine
  • Anatomical Variations
  • Interventional Cardiology

Background:

  • Coronary artery anomalies are congenital variations in the anatomy of the heart's major blood vessels.
  • Dual left anterior descending (LAD) coronary arteries are uncommon, with variations in origin and caliber.
  • Understanding these anomalies is crucial for accurate diagnosis and treatment planning.

Observation:

  • A patient presented with a dual LAD coronary artery system.
  • The normally originating LAD artery was hypoplastic (underdeveloped).
  • An anomalous LAD artery originated from the right aortic sinus with normal caliber, supplying the anterior left ventricular wall.

Findings:

  • The anomalous LAD artery coursed between the aorta and pulmonary artery.

  • This anomalous vessel supplied a significant portion of the anterior myocardial wall.
  • The anatomical configuration presented unique challenges for potential interventions.

    • Implications:

    • This rare coronary anomaly may complicate percutaneous coronary interventions (PCI).
    • Surgical revascularization strategies might need modification due to the anomalous vessel's course and supply.
    • Accurate pre-procedural imaging is essential for patients with this condition.
