Transcatheter closure of ventricular septal defect in aortic valve prolapse and aortic regurgitation

ObjectiveTo report intermediate follow-up result of transcatheter closure of ventricular septal defect (VSD) in presence of aortic valve prolapse (AVP) with or without aortic regurgitation (AR).MethodThis is a retrospective review of 19 patients with VSD with AVP with AR who underwent transcatheter closure in between September 2011–July 2014. Mean age was 8 years (1–16 years, standard deviation SD] 4.08 years) and mean weight was 26.03 kg (9–81.5 kg, SD 16.57 kg). Among them 2 had subarterial VSD, 6 had subaortic VSD and 11 had perimembranous VSD. All of them had mild AVP and 13 of them had AR (trivial or mild). Median VSD size was 4.3 mm (4–6 mm). Transcatheter closure was done either by retrograde technique using the Amplatzer Duct Occluder-II in 17 patients or antegrade technique using the Duct Occluder-I in 2 cases. Mean follow-up period was 18 months (12–36 months).ResultImmediate major complications were encountered in 2 (10.5%) cases. Significant aggravation of device related AR was seen in one case & device embolised to right pulmonary artery in another case and both of them were managed surgically.During follow up, 1 child had significant additional VSD requiring device closure. One child developed moderate AR, requiring surgery. None of the other had shown any increase in severity of AR.ConclusionDevice closure of VSD in presence of mild AVP and mild AR appears to be safe. Longer follow-up is necessary to draw final conclusion.
