In August 2010, the Nit-Occlud Lê (EUREVECO) became available for transcatheter coil occlusion of ventricular septal defects (VSDs). Retrospective European Registry for VSD Closure using the Nit-Occlud Lê-VSD-Coil; analysis of the feasibility, results, safety and follow-up of VSD-closure over a 3-year period in 18 European centers. In 102 of 111 patients (female 66), successful VSD closure was performed (mean age 8.2 years, mean weight 28.82 kg), 81 perimembranous VSDs (48 with aneurysm), 30 muscular VSDs, mean procedure time was 121.1 min, and mean fluoroscopy time was 26.3 min. Short- and midterm term follow-up was possible in 100/102 patients, there was 1 embolization and 1 explantation after 24 months. Immediate complete closure occurred in 49 of 101 patients (48.5%), trivial residual shunt was present in 51 (50.0%), closure rate was 95% after 6 months and 97% after 1 year. Out of the 102 patients, there were 2 severe complications (1.8%) (1 severe hemolysis, 1 embolization) and 8 moderate/transient (=7.2%) including 1 transient AV block. During a mean follow-up period of 31.3 months (range 24-48) and a total follow-up time of 224.75 patient years, no further problems occurred. VSD closure with the Nit-Occlud Lê VSD coil is feasible and safe with a minimal risk of severe side effects. The long-term effects and safety require further clinical follow-up studies.
A transcatheter technique is described for stabilization and retrieval of an embolized Amplatzer device, which was inadvertently deployed in the left atrium of a 2-year-old girl with hemodynamically significant atrial septal defect within the fossa ovalis. Since surgery was not available for immediate device retrieval, transcatheter means were chosen to prevent embolization of the device into the mitral valve. After stabilizing the device by creating a guidewire circuit through the wire mesh of the right atrial disk, the Amplatzer device was repositioned through the interatrial defect by snaring the microscrew. No residual shunting and perfect device position was recorded during Doppler echocardiography directly after the procedure as well as 1, 2, and 120 days after the intervention. Cathet. Cardiovasc.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
