Patent foramen ovale closure with... [Catheter Cardiovasc Interv. 2013] - PubMed - NCBI Patent foramen ovale closure with the Gore Septal Occluder (GSO); Initial UK experience. Department of congenital cardiology, Leeds general infirmary. Abstract Objectives: To report procedural outcome and short-term follow-up data for the Gore Septal Occluder (GSO), a new device for closure of patent foramen ovale (PFO). Background: Transcatheter closure of patent foramen ovale is an established treatment modality but no current device provides a perfect solution. The GORE septal occluder (GSO) has a number of design features which make it potentially attractive for closure of defects in the atrial septum. Methods: Data from 9 centres in the United Kingdom implanting the GSO device, submitted to an electronic registry for evaluation. Results: 229 patients undergoing PFO closure from June 2011 to October 2012 were included. Indications for closure were secondary prevention of paradoxical cerebral emboli (83.4%), migraine (2.1%), platypnoea orthodeoxia (3.9%) and other (10.5%). Median PFO size was 8mm and 34% and 39%, respectively, had long tunnel anatomy or atrial septal aneurysms. A GSO was successfully implanted in all cases. A single device was used in 98% but in 4 patients the initial device was removed and a second device required. Procedural complications occurred in 3% and later complications (e.g. atrial fibrillation, atrial ectopics, device thrombus) in 5.7% of cases. All patients have undergone clinical and echocardiographic follow up and all devices remain in position. Early bubble studies (median 0 months) with Valsalva manoeuvre in 67.2% were negative in 89%. Conclusions: The GORE septal occluder is an effective occlusion device for closure of patent foramen ovale of all types. Longer-term follow-up particularly to document later closure rates are required. © 2013 Wiley Periodicals, Inc. ncbi.nlm.nih.gov/pubmed/23766247
