Cardiovascular implants – Cardiac valve prostheses – Part 3: Heart valve substitutes implanted by transcatheter techniques (ISO 5840-3:2021)

Price from:
€ 104.75


This part of ISO 5840 is applicable to all devices intended for implantation as a transcatheter heart valve
substitute (see Annex A for examples).
This part of ISO 5840 is applicable to both newly developed and modified transcatheter heart valve
substitutes and to the accessory devices, packaging and labelling required for their implantation and for
determining the appropriate size of heart valve substitute to be implanted.
This part of ISO 5840 outlines an approach for verifying/validating the design and manufacture of a
transcatheter heart valve substitute through risk management. The selection of appropriate
verification/validation tests and methods are to be derived from the risk assessment. The tests may
include those to assess the physical, chemical, biological and mechanical properties of heart valve
substitutes and of their materials and components. The tests can also include those for preclinical in vivo
evaluation and clinical evaluation of the finished heart valve substitute.
This part of ISO 5840 defines operational conditions and performance requirements for transcatheter
heart valve substitutes where adequate scientific and/or clinical evidence exists for their justification.
This part of ISO 5840 includes considerations for implantation of a transcatheter heart valve substitute
inside a pre-existing prosthetic device (e.g. valve-in-valve and valve-in-ring configurations).
