Clinical Valve Thrombosis After Transcatheter Aortic Valve-in-Valve Implantation

300 patients who underwent transcatheter aortic valve-in-valve (ViV) implantation from the Valve-in-Valve International Data Registry. The surgical valve was stented in 86.3% and stentless in 13.7% of cases; the transcatheter heart valve was self-expanding in 50%, balloon-expandable in 49%, and mechanically expanding in 1.0%.
