Abstract

We report about our initial experience for the in 2005 modified Helex (Gore) device for closure of atrial septal defects (ASD) and persistent foramen ovale (PFO). Major changes were made at the delivery system for simplifying the Helex implantation procedure. We treated 11 patients, 8 children and 3 adults, with ages between 3 and 62 years. In 10 patients the diagnosis was a relevant ASD with volume overload of the right heart (Left to right shunts between 30 and 50%). One adult (age 58 years) have had a small left to right shunt with a PFO-like defect and the history of 2 neurologic embolic events. In 3 patients we found 2 defects. In all patients a Helex occluder was implanted successfully. The mean fluoroscopy time was 8,4 minutes. The immediate occlusion rate after 24 hours was 91%. In all cases there was a very good adaptation of the device to the anatomical structures. In this small series, the Helex occluder appears to offer a reliable system of occlusion for small and moderate ASDs and for PFO with minimal risk of major complications.
