Please note that this standard has not yet been harmonised and thus cannot be used for CE marking. Until harmonisation of this standard has been achieved, please use one of the following standards: 




This part of ISO 5840 is applicable to heart valve substitutes intended for implantation in human hearts,
generally requiring cardiopulmonary bypass and generally with direct visualization. See Annex E for
examples of surgical heart valve substitutes and their components.
This part of ISO 5840 is applicable to both newly developed and modified surgical heart valve substitutes
and to the accessory devices, packaging, and labelling required for their implantation and for determining
the appropriate size of the surgical heart valve substitute to be implanted.
This part of ISO 5840 outlines an approach for verifying/ validating the design and manufacture of a
surgical heart valve substitute through risk management. The selection of appropriate qualification tests
and methods are derived from the risk assessment. The tests may include those to assess the physical,
chemical, biological, and mechanical properties of surgical heart valve substitutes and of their materials
and components. The tests can also include those for pre-clinical in vivo evaluation and clinical evaluation
of the finished surgical heart valve substitute.
This part of ISO 5840 defines operational conditions and performance requirements for surgical heart
valve substitutes where adequate scientific and/or clinical evidence exists for their justification.
For novel surgical heart valve substitutes, e.g. sutureless, the requirements of both this International
Standard and ISO 5840-3 might be relevant and shall be considered as applicable to the specific device
design and shall be based on the results of the risk analysis.
