Key result
The abstract provides background on congenital coronary artery fistulas and their pathophysiological consequences, without reporting specific clinical outcomes.
Case Report
The text introduces the pathophysiology of congenital coronary artery fistulae, which can lead to coronary steal, volume overload, and myocardial insult, setting the stage for repair without cardiopulmonary bypass in a symptomatic newborn.
Supports off-pump CAF repair in select neonates without ischemia; leaves open need for comparative data before broader adoption.
Congenital coronary artery fistula (CAF) is a rare connection between a coronary artery and a cardiac chamber. Single or multiple fistulae can be present at once and may originate from any coronary artery. The most common CAF is between the right coronary artery (RCA) and right heart chambers.1 The blood flow from a coronary artery into a low-pressure cardiac chamber through a fistula produces a coronary steal and left ventricular volume overload, both of which can lead to myocardial insult. In addition, the amplified flow due to pressure gradient can induce aneurysm formation and coronary intimal injury.
