ISO 5840 Bioprosthetic Heart Valve Hydrodynamic Testing
The ISO 5840 standard provides a comprehensive framework for the hydrodynamic testing of bioprosthetic heart valves. This service is critical in ensuring that heart valve devices meet stringent performance and safety requirements before being approved for clinical use.
Hydrodynamic testing assesses the flow characteristics of blood through the prosthetic valve under various loading conditions, which is essential to determine how well the valve will function within the circulatory system. This process involves subjecting the valve to a range of pressures and flow rates that simulate real-world cardiac conditions.
At Eurolab, our experts conduct these tests using advanced instrumentation capable of replicating physiological environments. The test setup includes specialized chambers where the heart valve is mounted and subjected to controlled pressure cycles mimicking those encountered during normal cardiac function.
The primary goal of this testing is to evaluate the hemodynamic performance of the valve, which encompasses several key parameters:
- Hemolysis
- Thrombogenicity
- Blood flow dynamics
- Leaflet motion and flexibility
The tests are conducted in accordance with ISO 5840, which provides detailed guidelines for the testing method, including specimen preparation, test setup, and data analysis. Compliance with this standard ensures that the results of our testing are internationally recognized and accepted.
Our team of professionals is well-versed in all aspects of this testing procedure, from initial consultation through to final report generation. We offer a full range of services including:
- Pre-test consultation
- Specimen preparation
- Testing and data acquisition
- Data analysis and reporting
- Post-test recommendations for improvement
The results of this testing are crucial in the development cycle of cardiac devices. By ensuring that the valve functions optimally under various conditions, we help manufacturers reduce risks associated with device malfunction.
