Abstract
Atrial septal defect (ASD) transcatheter occlusion techniques have become alternatives to surgical procedures. We evaluated the efficiency, safety and feasibility of the Occlutech Figulla-N device in percutaneous closure of secundum ASDs. 62 consecutive patients were referred for ASD closure using Occlutech devices. Patients were divided into two groups based on age. group A (42 patients) with age < 18 years old and group B (20 patients) with age {u2265} 18 years old. Defect size and total interatrial septal length were estimated by transthoracic (TTE) and/or transesophageal (TEE) echocardiography in 3 views. Procedures were performed under fluoroscopic and TTE or TEE guidance. Patients were followed-up at 1, 3, 6 months with TTE. Patients in group A were 4.8 ± 2.0 years and 16.6 ± 6.3 kg. Mean ASD diameter was 14.9 ± 4.2 mm by TTE and 16.1 ± 4.7 mm by TEE. Median device size was 18 mm (range 10.5-27 mm). Device was successfully placed in all 42 patients using standard device size selection criteria. During mean follow-up of 12 + 3 months, no major complication were observed. Patients in group B were 32.9 ± 9.7 years. Mean ASD diameter was 21.7 ± 7.3 mm by TTE and 24.6 ± 7.7 mm by TEE. Median device size was 27 mm (range 10.5-40 mm). ASD was successfully closed in 20 patients after 22 percutaneous attempts
