We report the successful transcatheter closure of the right pulmonary artery fistula to the left atrium in a 4-year-old boy, who had presented with cyanosis and easy fatigability, identified after two-dimensional echocardiogram with bubble contrast study, computed tomography (CT) angiography, and cardiac catheterization. The fistula was successfully closed by a transcatheter approach using an 18/16 duct occluder device. There was marked improvement clinically and no complication on 2-months follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
