Description

Background: The ideal device for percutaneous patent foramen ovale (PFO) occlusion should provide effective closure with long-term biocompatibility and it should have a low profile without interfering with adjacent cardiac structures. Long-term data regarding safety and efficacy of the GORE Septal Occluder (GSO) are lacking. The aim of this study was to investigate the short- and mid-term clinical and echocardiographic outcomes of this device. Methods and Results: Forty-five consecutive patients with clinically significant PFO were treated with GSO and their results were compared with those of 45 consecutive patients treated with Amplatzer PFO device (APO). Primary endpoint was the incidence of 6-month residual right-to-left shunting (rRLS). The procedural results and the recurrence of embolic events (REE) at 1 year were also investigated. No differences in terms of embolic risk profile and echocardiographic parameters were observed between the 2 groups. GSO was successfully implanted in all patients without device-related complication. In 2 patients for whom device position was not optimal, the GSO was easily retrieved and a new GSO was successfully repositioned. Immediate moderate–severe rRLS was similar in 2 groups. No cases of severe 6-month rRLS were registered. Two patients (4%) and 1 patient (2%) had moderate 6-month rRLS in the GSO and APO group, respectively (P=NS). No cases of REE were registered at 1-year follow-up. Conclusions: GSO appears a valuable alternative to Amplatzer device for PFO occlusion.  (Circ J 2013; 77: 2922–2927)<br>
