Difetto interatriale ostium secundum: chiusura transcatetere

Transcatheter closure of ostium secundum atrial septal defect with the Amplatzer Septal Occluder was performed in 40 patients (from March 2000 to December 2003) ranging in age from 2 to 67 years (median 23 years). Accurate assessment by transesophageal echocardiography before attempting the transcatheter closure was performed. The stretched diameter of the defects that were closed ranged from 9 to 32 mm (median 17.6 mm) and device sizes ranged from 10 to 34 mm (median 18 mm). The defects were closed with a single device and in one case of the multiple defects are used two devices. At 6 month follow-up 30/31 (96.7%) patients had complete closure of their defects. The only complication encountered was a device embolization in a 16-year-old girl with surgical removal. The Amplatzer Septal Occluder device has demonstrated excellent clinical success in the closure of secundun atrial septal defect.
