title: Patent foramen ovale with right atrial septal pouch.
abstract: 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.
