A coronary cameral fistula is a type of coronary artery fistula and is defined as a fistulous communication or communicating vessel from the coronary artery into any of the cardiac chambers.
Epidemiology
It is considered the most common type of coronary artery fistula. They may be present in less than 1% of the population and have been described in around 0.1-0.2% of coronary angiographic studies. They are thought to account for 0.2-0.4% of congenital anomalies of the heart.
Pathology
Origin
- right coronary artery (RCA): ~ 55%
- left anterior descending artery (LAD) ~ 35%
- both of RCA and LAD
Draining chamber
- right ventricle: ~ 41%)
- right atrium: ~ 26%
- left atrium and left ventricle: ~ 3-5%
