  • Title: How to Define Durability of Transcatheter and Surgical Bioprosthetic Aortic Valves: Facts and Misconceptions.
    Author: Capodanno D, Søndergaard L.
    Journal: JACC Cardiovasc Interv; 2020 Jan 27; 13(2):257-260. PubMed ID: 31973798.
    Abstract:
    In the evolving scenario of transcatheter aortic valve replacement (TAVR), the topic of bioprosthetic valve durability is becoming increasingly important. Unfortunately, the definition of long-term durability of surgical and transcatheter bioprostheses has been inconsistent over time. Comparative studies of TAVR and surgical aortic valve replacement, or studies comparing TAVR devices, would benefit from the use of standardized definitions of valve durability. The definitions of structural valve deterioration and bioprosthetic valve failure developed by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) have been endorsed by both the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) and embraced by many investigators worldwide. In this viewpoint, the authors discuss the strengths and limitations of such approach, which is intended to balance the need for accuracy and simplicity in reporting of long-term durability.
