Successful percutaneous coil embolization of a severely tortuous coronary artery fistula using the mother-child-grandchild technique via a GuideLiner catheter

Abstract

Coronary artery fistula is an uncommon congenital disease that requires invasive treatment for symptomatic patients. Although percutaneous intervention has become the popular treatment option, surgical treatment is preferred for severely tortuous coronary artery fistulas. We report a case of an extremely tortuous coronary artery fistula successfully treated with the support of the GuideLiner catheter and the mother-grandchild technique.
