Infective endocarditis on an occluder closing an atrial septal defect

Abstract
Closure of atrial septal defects be means of intravenous catheterisation has been undertaken using a variety of devices as an alternative to surgical closure.1–5We describe the first case, to the best of our knowledge, of infective endocarditis complicating a successful transcatheter closure. This highlights the potential risk of this procedure, and emphasises the need for appropriate antibiotic prophylaxis until complete endothelialization of the device has occurred.
