Perforation of aortic root as secondary complication after implantation of patent foramen ovale occlusion device in a 31-year-old woman.

Author information

Department of Internal Medicine and Cardiology, Dresden University of Technology, Germany.


Transesophageal echocardiography (TEE) revealed a 3-mm-large patent foramen ovale (PFO). No other reason for these neurological events could be found and the patient underwent percutaneous closure of the PFO with a CARDIA Star 03/30 device without periprocedural complications. Four weeks later, the patient underwent a routine control of device without any adverse clinical symptoms. Surprisingly, echocardiography revealed a perforation of the aortic root by an umbrella strut with a small shunt from the aortic root to the right atrium. Magnetic resonance imaging (MRI) confirmed the diagnosis of device malposition. Consecutively, the patient underwent minimal invasive surgery. After removal of the single perforating strut, the bleeding lesion was closed. The patient remained free of any additional complications during the postoperative course and up until now has had uneventful follow-ups.
