Late aortic perforation with an Atriasept device resulting in life-threatening tamponade.

Patients with compelling evidence of cryptogenic stroke due to patent foreamen ovale (PFO) are increasingly likely to be offered percutaneous closure of the defect. With improvements in technique there is now a high procedural success rate with low rates of periprocedural complications. Late complications are also rare, but include late perforation of the aortic root, which is rapidly progressive and potentially fatal. This has lead to the development of lower profile devices, which aim to reduce the risk of both early and late complications. At this stage, it is not clear if lower profile devices have safety profiles which are superior to the more established devices. We report the first case of late perforation of the aortic sinus by the lower profile Atriasept (Cardia) device presenting as life threatening cardiac tamponade in an adult who previously underwent percutaneous PFO closure.
