Patent foramen ovale with right atrial septal pouch.

A patent foramen ovale (PFO) is a communication across the inter-atrial septum and a right atrial septal pouch (RASP) is an indentation of the atrial septum caused by an incomplete fusion of the septum primum and septum secundum with its base opening into the right atrium. A 63-year-old male who had a history of two strokes and episodes of transient neurological deficit was diagnosed to have a small right-to-left shunt. At the time of PFO closure, an angiogram of the atrial septum revealed a small PFO associated with a RASP. The small PFO was crossed with a straight-tipped guide wire and was closed using a 25-mm GORE CARDIOFORM Septal Occluder (W.L. Gore and Associates, AZ). It is hypothesized that stagnant blood in the RASP may generate a clot that can cross the PFO and cause an infarct. © 2015 Wiley Periodicals, Inc.

Iatrogenic erosion of the septum primum resulting in an atrial septal defect with left-to-right shunt: a rare pitfall of patent foramen ovale percutaneous closure.

Iatrogenic erosion of the septum primum after foramen ovale closure is an anecdotal event. We report the case of a 39-year-old woman admitted to our institution for multifocal cryptogenic cerebral ischemia and a patent foramen ovale (PFO) associated with an aneurysm of the septum primum. The patient underwent percutaneous closure of the PFO with an Amplatzer PFO Occluder device. At the 6-months follow up, the device was in the right position, but a jagged defect of the septum primum and evidence of significant left-to-right shunting was detected. The atrial septal defect was then repaired by a surgical approach. Although this event is not life-threatening, it should be considered as a therapeutic pitfall, resulting in a risk of paradoxical embolism recurrences and long-term hemodynamic impairment. © 2013 Wiley Periodicals, Inc.
