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.
Core tip: We describe the tardiest case of transcatheter aortic valve replacement (TAVR) thrombosis ever reported. A 64-year-old woman with severe symptomatic aortic stenosis underwent TAVR with a first-generation SAPIEN prosthesis. More than four years (> 54 mo) following implantation, she presented with a severe symptomatic prosthesis dysfunction (stenosis) which was successfully treated with oral anticoagulation.
