ObjectivesTo 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).BackgroundTranscatheter VSD closure has achieved encouraging results but more follow-up studies are needed.Patients and methodsBetween 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.ResultsThe 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.ConclusionUsing Nit-Occlud_ Lê VSD-Coil to close VSD is safe and feasible in VSDs with various morphology.

Perforation of the atretic PV in selected cases with membranous atresia and patent infundibulum using the stiff end of a coronary wire is an effective alternative to using radiofrequency perforation.

Objective to describe an approach to perform safe transcatheter closure of Atrial Septal Defect (ASD)/Patent Foramen Ovale (PFO) associated with large redundant Eustachian Valve. Background Transcatheter device closure of ASD/PFO is feasible in a great majority of patients. However, the presence of a huge mobile Eustachian Valve can compromise device placement. Patients and Methods Six patients (3 PFO and 3 ASD patients) with a huge redundant Eustachian valve were included. Two patients had PFO with long tunnel and were closed with Occlutech FigullaFlex II PFO occluders sized 23/25 and 27/30 respectively. The other PFO patient had an associated atrial septal aneurysm (ASA) and was closed with a 25 mm Amplatzer Multi-Fenestrated Septal Occluder “cribriform” device (St. Jude Medical – Abbott Vascular). The three ASDs were closed by regular ASD occluders (2 Flex II ASD Occluders sized 30 and 33 mm and 1 Amplatzer ASD Occluder sized 24 mm). Eustachian valve was successfully held with a steerable ablation catheter to deflect it against the lateral right atrial wall, keeping it away from the inter-atrial septum to prevent its entrapment or interference with the cable, the sheath or the device. Results All ASDs/PFOs have been successfully closed with no complications with free inferior vena cava (IVC) flow, with no residual inter-atrial shunt and the eustachian valve is not interfering with the device. Conclusions Safe percutaneous ASD/PFO closure can be achieved with proper control of a large redundant Eustachian valve.
