A case of infective endocarditis in an 8-year-old boy 3 months after transcatheter atrial septal defect closure using Figulla Flex II occluder

摘要

Infective endocarditis is a rare complication of atrial septal defect closure using transcatheter procedure. We report about infective endocarditis in an 8-year-old boy 3 months after transcatheter closure using a Figulla Flex II atrial septal defect occluder. Transesophageal echocardiography showed vegetation attached to the left atrium side of the device. Device removal and atrial septal defect closure were performed. The device was less endothelialized on the left than on the right atrium side. Therefore, insufficient endothelialization may cause infective endocarditis.Some complications of atrial septal defect closure by transcatheter procedure require surgical removal, such as perforation of the aorta or atrial wall. Infective endocarditis with secundum atrial septal defect is a rare but also important complication1 because it is sometimes found after transcatheter closure and it requires surgery.
