Abstract

BACKGROUND: The aim of this study was to assess safety, efficacy, and clinical outcome of the IrisFIT PFO Closure System (Lifetech Scientific) for transcatheter closure of patent foramen ovale (PFO) in patients with a history of cryptogenic stroke, transient ischemic attack (TIA), or peripheral embolization.

PATIENTS AND METHODS: We report the results of 60 consecutive patients undergoing PFO closure with the IrisFIT occluder for secondary prevention of paradoxical embolization. All cases were analyzed for periprocedural and device-related adverse events up to 12 months after implantation. In addition, the patients were evaluated for complete defect closure with transesophageal echocardiography (TEE) after 1 month, 6 months, and (if indicated) 12 months. Mean patient age was 53 ± 14 years and 37 patients (62%) were males. All patients had a history of at least 1 cryptogenic stroke, TIA, or peripheral embolization.

RESULTS: Technical success was achieved in all 60 procedures. The mean procedure time was 28 ± 11 minutes. There were no periprocedural or device-related complications up to 12 months after the implant. Successful defect closure at 6 months post device implantation was achieved in 56 cases (93.3%). Within 12 months of follow-up, 2 patients had recurrent TIAs, both with complete PFO sealing at the last TEE prior to the event.

CONCLUSION: The IrisFIT PFO Closure System can be used safely and with high technical success for secondary prevention of cryptogenic stroke or peripheral embolization.
