Percutaneous Hydrogel Coil Embolization of Aneurysms and Coronary Artery Fistulae in Congenital Heart Disease

Tex Heart Inst J. 2021 Jul 1;48(3):e207312. doi: 10.14503/THIJ-20-7312.

Abstract

Patients with congenital heart disease frequently have aneurysms or coronary artery fistulae that necessitate treatment. Metal vascular coils have been a mainstay of treatment for these lesions. In 2002, coils coated or filled with expandable hydrogel were introduced to treat cerebral aneurysms; however, the literature on their use in patients with congenital heart disease is limited. We present 5 cases in which large vascular lesions in children or adolescents with congenital heart disease were successfully occluded with hydrogel coils.
