Abstract Background The feasibility of percutaneous closure ventricular septal defects (VSD) in children has been previously proven. However, data on long-term outcomes are limited. We aim to evaluate the long-term outcome of our experience with percutaneous closure of VSD using various occluders. Methods Retrospective institutional analysis of children who underwent transcatheter closure of perimembranous and muscular VSDs between September 2012 and February 2020. Patient demographics, procedural, and long-term follow-up data were comprehensively analyzed. Patients who lost to follow-up within two years post-procedure were excluded. Results We identified 75 patients (54.7% males) with a median of 66 months (IQR, 46–96). The closure success rate at one year was 95.7%. Complete heart block was detected in two patients early post-procedure and resolved with steroids. The VSDs were perimembranous (52%), muscular (33.33%), and residual (14.67%). Implanted devices were Pfm Nit-Occlud LeˆVSD Coil (42.7%), HyperionTM VSD Muscular Occluder (28%), Amplatzer VSD muscular occluder (10.7%), Amplatzer Duct Occluder (14.7%), Occlutech Muscular VSD Occluder (2.7%), and Amplatzer Duct Occluder II (1.3%). No new arrhythmia or valve regurgitation was detected after two years post-procedure. Persisted complications on long-term follow-up included: residual shunting in 3(4%), mild tricuspid regurgitation in 2(2.7%), and aortic regurgitation in 2(2.7%), with one immediate post-catheterization mild aortic regurgitation worsened during follow-up, requiring surgical repair of VSD three years after device implantation. No deaths were reported. Conclusion Long-term outcomes of pediatric transcatheter VSD closure using different devices are satisfactory. Post-procedural adverse events are limited, but long-term surveillance is necessary to monitor their progression.
