Key result
Percutaneous closure of a patent foramen ovale with a Cardiastar device resulted in late cardiac tamponade one year later due to perforation of the left atrial roof and aortic root by device struts.
Case Report (n=1)
This case highlights the rare but severe risk of late cardiac tamponade due to device erosion after percutaneous PFO closure, emphasizing the importance of long-term follow-up.
Supports vigilance for late erosion after PFO closure; leaves open device-specific risks and optimal surveillance duration.
We report the case of a 35-year-old man who had a transient ischemic cerebral attack and then underwent a percutaneous closure of the patent foramen ovale (PFO) with a Cardiastar device. One year later, the patient developed a cardiac tamponade due to an important hemorrhagic pericardial effusion. Transoesophageal echocardiography showed that one of the struts had impinged on the aortic root in the region adjacent to the transverse pericardial sinus. Therefore, we speculated that the strut had passed through the aortic wall by slow erosion, leading to the pericardial effusion. Cardiac CT and subsequent surgery confirmed the perforation of the left atrial roof and the aortic root by two struts of the device. This is the first reported case of late cardiac tamponade and underscores the importance of long-term follow-up after PFO closure device implantation.

Christen et al. (2005) conducted a case report in Patent foramen ovale (n=1). Percutaneous closure of the patent foramen ovale with a Cardiastar device was evaluated on Late cardiac tamponade. Percutaneous closure of a patent foramen ovale with a Cardiastar device resulted in late cardiac tamponade one year later due to perforation of the left atrial roof and aortic root by device struts.
