[edit] Discussion of Anomalous coronary artery

  • Approximately 20% of coronary artery anomalies produce life-threatening symptoms (arrhythmias, syncope, myocardial infarction, or sudden death).
  • Congenital coronary artery anomalies are the second most common cause of sudden death due to structural heart disease in young athletes.
  • Benign vs malignant course of anomalous coronary arteries
    • Anomalous vessel that crosses between the aorta and the main pulmonary artery (interarterial course) may be associated with a poorer outcome and requires surgical repair.
    • This may be either a left coronary artery originating from the right coronary sinus or a right coronary artery emanating from the left coronary sinus.
    • During physical activity, the aortic wall stretches and dilates to support the increased cardiac output, which compresses the anomalous vessel against the main pulmonary artery.
