ADO II in Percutaneous VSD Closure in Pediatric Patients

Main aim of our study to show that ADO II device can be used for the small ventricular septal defects successfully and safely with low complication rates in pediatric population.

It is hard to find an ideal device to use for every VSD successfully. If inappropriate device was chosen; complication rate increases, procedure time gets longer that prolongs exposure to ionizing radiation. Therefore interventionalists are in the search for new ideal devices.

Between the dates April 2011-October 2014, 21 VSD closures with ADO-II device. were performed. Twenty patients were included, age ranged between 4 months 18 years. Weight of the patients was between 5-76 kg.

VSD diameter ranges between 2-6 mm (3.75 ± 1.25). VSD types were muscular in 2 patients, rest of them were perimembranous type. Most of the perimembranous defects (19/21) were aneursymatic and tunnel shaped. All the cases were successfully closed, no major complications were reported. There was no incidence of left bundle branch block, P-R prolongation, or complete heart block.

Considering perimembraneous ventricular septal defects as difficult and risky for percutaneous closure because of its proximity to aortic, atrioventricular valves and conduction tissue, we suggest that ADO II device can be safely and effectively used for such defects in particular if an aneurysm formation is present which is also compatible with the literature.
