This device enables both visual inspection and active measurement of the aortic valve’s condition and geometry during open-heart surgery.
By performing this step while the heart remains arrested, the device can significantly reduce procedure time.

Additionally, it makes valve-sparing interventions more feasible, which is good news for the patient.
The AVP device connects securely to the aortic graft prosthesis during the intervention, with the heart at rest.
The first prototype was invented at Leiden University Medical Center (Leiden UMC) by Prof Dr Mark Hazekamp and Dr Bardia Arabkhani. Versions 2.0 and 3.0 were co-invented by our team and will be clinically tested at Leiden UMC and Erasmus UMC.
We provided a complete Design History File and the Investigational Medical Device Dossier (IMDD) for clinical trial applications.
New clinical trials are planned for 2026 at several European medical centres.
