Insights
Giant coronary artery fistulas can cause right atrial tachycardia. Successful fistula treatment eliminated the tachycardia, suggesting a direct link between this rare coronary anomaly and cardiac arrhythmia. This is the first reported case of this association.
Area of Science:
- Cardiology
- Cardiac Electrophysiology
- Congenital Heart Disease
Background:
- Coronary artery fistulas are the second most common coronary anomaly.
- A coronary fistula is an abnormal connection between a coronary artery and a heart chamber or major vessel.
- Treatment options include percutaneous embolization and surgical repair.
Abstract:
Coronary artery fistulas are the second most frequently seen coronary anomaly following abnormalities of coronary artery origin and distribution. A coronary fistula is defined as a direct communication between a coronary artery and any cardiac chamber or vessel. Treatment options include percutaneous embolization and surgical intervention. Herein, we present a case of a giant coronary artery fistula and right atrial tachycardia that was induced during a diagnostic electrophysiologic study but was not inducible after the successful treatment of the fistula. This is the first case indicating this association.
