Severe tricuspid stenosis during percutaneous occlusion of perimembranous ventricular septal defect with the new Amplatzer device.

BACKGROUND: The new Amplatzer device has been used with success for occlusion of the perimembranous ventricular septal defects and the index of complications is very low. RESULTS: The reported case corresponds to a very rare severe acute tricuspid stenosis, caused by adherence of the prosthesis to the anterior tricuspid leaflet. CONCLUSION: Device release was achieved by manipulation on the tricuspid apparatus.
