Right Coronary Artery to Coronary Sinus Fistula with Giant Coronary Sinus Aneurysm.

Abstract

Coronary artery fistulas represent abnormal connections between the coronary arterial system and cardiac chambers or other vascular structures. Depending on various morphological characteristics of the fistula, the clinical presentation may vary from being asymptomatic to having clinically significant myocardial ischemia. The present case highlights a rare instance of a right coronary artery to coronary sinus fistula with a giant coronary sinus aneurysm.
