  • Title: 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.
    Author: Scacciatella P, Biava LM, Marra S.
    Journal: Catheter Cardiovasc Interv; 2014 Sep 01; 84(3):494-6. PubMed ID: 24399577.
    Abstract:
    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.
