title: Very late transcatheter heart valve thrombosis.
abstract: We describe a case of very late transcatheter heart valve (THV) thrombosis of a first-generation SAPIEN prosthesis (Edwards Lifesciences, Irvine, CA) implanted in a 64-year-old woman with severe symptomatic aortic stenosis. More than 54 mo after implantation, she presented with severe symptomatic prosthesis dysfunction (stenosis) which was successfully treated with oral anticoagulation. To our knowledge, this is the tardiest case of THV thrombosis ever reported. This case should increase clinical awareness for THV thrombosis even beyond the first two-year period following implantation.
