| Summary: | Objectives: To assess safety, efficacy and follow-up results of transcatheter closure of ventricular septal defect (VSD) using Nit-Occlud_ Lê VSD Coil (pfm medical, KÖln, Germany). Background: Transcatheter VSD closure has achieved encouraging results but more follow-up studies are needed. Patients and methods: Between January 2012 and December 2013 in the cardiology department, Tanta University Hospital, Tanta, Egypt, 80 patients underwent percutaneous VSD closure using Nit-Occlud_ Lê VSD Coil. Early and mid- term follow-up was done for 3 years, follow-up was concluded in 2016. Results: The mean age of patients was 5.34 ± 3 years, and their mean weight was 17.24 ± 8.17 kg. Overall, 77 of 80 patients had perimembranous VSD with aneurysmal tissue; eight had multiple right ventricular exits, 14 had deficient aortic rim, two had high outlet muscular, and one had Gerbode defect. The procedure was successful in 98.75% of patients, and was aborted in one patient because of the development of complete heart block and the coil had to be removed. The mean procedure time was 104.98 ± 9.50 minutes. The mean fluoroscopy time was 30.58 ± 2.79 minutes. The immediate complete occlusion rate was 62%, which increased to 82.3% on the second day, and 94.9% by the 3rd month, and 97.5% by 1 year. There was a significant decrease in mitral incompetence after 6 months of follow-up (p = 0.002), and only one patient had trivial aortic incompetence prior to the procedure that remained the same during follow-up period. Conclusion: Using Nit-Occlud_ Lê VSD-Coil to close VSD is safe and feasible in VSDs with various morphology. keywords: Ventricular septal defect, Transcatheter closure, Nit-Occlud® Lê VSD Coil
