In this episode of Crux of Cardio, Jordan Burgin sits down with Arnaud Mascarell, CEO and Co-Founder of FineHeart, the Bordeaux-based company behind the FlowMaker, a fully implantable cardiac assist device that works in synchrony with the heart’s natural contraction rather than replacing it.

Arnaud shares the full journey: 18 years at Medtronic pioneering CRT pacemakers, the origin story that started with a child’s toy boat, why the current approach to heart failure is fundamentally broken, and what it takes to spend a decade building a device that nobody else has been able to replicate. He also opens up on fundraising in European medtech, securing a €48M EU grant, and why he measures success in patients saved rather than acquisition price.
