Background. Transcatheter closure of the patent ductus arteriosus is a well established procedure. The objective of this study was to assess the effectiveness and the safety of the Amplatzer duct occluder. Methods and Results. Occlusion of the patent ductus arteriosus was attempted in 23 patients. The median weight was 11.7 Kg (range, 5 kg-42.4 kg) with a mean ductus diameter of 3.7 mm (range, 1.6-7.2 mm). The immediate closure rate was 86% with a closure rate of 100% at 6 months, 1 year and 2 years following device placement. There was one device embolization that occurred immediately following device placement. No patient had aortic narrowing or pulmonary artery stenosis following the procedure. Conclusions. The Amplatzer duct occluder is safe and effective in the closure of a patent ductus arteriosus up to 7.2 mm in diameter. Selecting a device at least 1-2 mm larger than the minimal ductal diameter can minimize embolization.
