Case ReportsTranscatheter membranous ventricular septal defect closure through a mechanical aortic prosthesis using the Amplatzer membranous ventricular septal defect occluder.
An iatrogenic ventricular septal defect (VSD) after aortic valve replacement is rare, but represents a significant complication. Repeat surgery to repair such a defect carries a high surgical risk. ⋯ We describe the successful transcatheter closure of an iatrogenic VSD with an Amplatzer membranous VSD occluder in a patient with previous combined mitral and aortic mechanical valve replacements. The device was implanted through a CarboMedics mechanical valve in the aortic position.

Stenting of stenotic or occluded iliofemoral veins, superior and inferior vena cavae in children with congenital heart disease: acute results and intermediate follow up.
To determine the short and intermediate term outcome following systemic venous stent placement in children with congenital heart disease. ⋯ Systemic venous stents are safe and effective in recanalizing stenosed or occluded vessels. At follow-up, reocclusion can occur, however, previously placed stents can be safely recanalized if necessary. Future studies will determine if stenting is indicated in a broader population.
