Background: Coronary fistula is a relatively rare cardiac disease. The incidence of coronary fistula flowing into the right heart structure is much higher than in inflow into the left heart structures. Opportunities for surgical intervention and treatment strategies for these patients still need to build more consensus.
Case presentation: Here, we report a case of right coronary artery-left ventricular fistula combined with a giant coronary artery aneurysm during the treatment course.
Conclusion: Because of its rarity as well as its specificity of coronary artery fistula, each case requires an individualized evaluation. More consideration also can be given to the choice of surgical approach.
