    Abstract:
    OBJECTIVE: To evaluate the safety and efficacy of the Occlutech patent foramen ovale (PFO) device at long-term follow-up (FU). BACKGROUND: The Occlutech device has been proven safe and effective six-months after percutaneous PFO closure. We describe the safety and efficacy after more than 1,300 patient-years of FU. METHODS: All consecutive patients who underwent PFO closure between October 2008 and December 2015 were included. All complications were registered. Residual right-to-left shunt (RLS) was diagnosed using contrast transthoracic echocardiography and graded as minimal, moderate, or severe. RESULTS: In total, 250 patients (mean age 53.5 ± 10.7 years, 46.8% female) underwent percutaneous PFO closure using the Occlutech device. Mean FU was 5.9 ± 1.8 years, a total of 1,345 patient-years. Transient ischemic attack (TIA) or stroke was the main indication for closure (89.6%). Implantation was successful in 100%, no major complications occurred. Minor complications were inguinal hematoma in 16 patients (6.4%), pericardial effusion without the need for intervention in one patient (0.4%) and a supraventricular tachycardia in one patient (0.4%). A moderate or large shunt at one-year follow up was present in 5.9%. A cerebrovascular vascular event occurred in 2.0% at 1-year FU (four TIA, one stroke) and in 7.4% at long-term FU (nine TIA, eight stroke). The total cerebrovascular event rate (TIA and CVA) was 0.02% per patient-year of FU, with a stroke rate of 0.01%. CONCLUSION: The Occlutech device appears to be safe at long-term FU with a very low annual cerebrovascular event rate and a low moderate to large shunt rate at 1-year FU.
