The Amplatzer duct occluder (ADOII) and Piccolo devices for patent ductus arteriosus closure: a large single institution series.

Purpose: Evaluate Piccolo and ADOII devices for transcatheter patent ductus arteriosus (PDA) closure. Piccolo has smaller retention discs reducing risk of flow disturbance but residual leak and embolization risk may increase.

Methods: Retrospective review of all patients undergoing PDA closure with an Amplatzer device between January 2008 and April 2022 in our institution.

The Amplatzer Duct Occluder II Additional Sizes device for transcatheter PDA closure: initial experience.

Objectives: To present our initial experience with the Amplatzer Duct Occluder II Additional Sizes (ADOIIAS) device.

Background: The ADOIIAS is a modified PDA closure device of various lengths and widths with small disks to avoid flow disturbance in the pulmonary arteries and descending aorta.

Patient Population: All patients who underwent attempted closure with an ADOIIAS device at our institution CATHETERIZATION: Following aortography the PDA was closed using a 4-5Fr delivery system from the pulmonary or aortic side with an ADOIIAS.
