UNLABELLED: Amplatzer Duct Occluder II (ADO II) is especially designed for closing long ducts in infants. The experience with off-label use of ADO II in non-ductal positions is limited.
AIM: To evaluate feasibility of use of ADO II in non-ductal positions, incidence of complete heart block (CHB), advantages and disadvantages.
MATERIAL AND RESULTS: Out of 79 defects closed with ADO II, 61 had perimembranous, 12 apical/mid-muscular ventricular septal defects (VSD), 4 Gerbode defects, one each of coronary arterio-venous fistula and aorto-right ventricular tunnel. Age ranged from 8 months to 21 years (mean 8.9 ± 4.02 years, median 9 years). The mean fluoroscopy time was 5.2 ± 1.1 min with range 4.2-9.2 min. Complete closure was achieved in all. Three cases developed transient junctional bradycardia, treated with steroids. One patient who developed CHB (1.3%) needed temporary pacing.
DISCUSSION: ADO II is a low profile device. It can be easily delivered through a 5F guiding catheter and needs very short fluoroscopic time as arteriovenous loop is not needed. The cost is 1/3 of regular ventricular septal occluders. The CHB that is a major challenge for closure of VSDs is less common with soft, specially designed ADO II, which does not compress the conducting system.
CONCLUSIONS: Use of the ADO II in non-ductal positions can be achieved with high success and low complication rates, especially CHB; its use is also associated with significantly reduced procedure time and device cost. Device size availability restricts use of the ADO II to defects up to 6 mm in diameter. © 2013 Wiley Periodicals, Inc.
