Innovating a Better Way.
CroíValve’s mission is to help more patients suffering from tricuspid regurgitation with a new, minimally invasive heart valve device called the DUO™ System.

Welcome to DUO™.
A new way forward for a new era in heart care.
Tricuspid Regurgitation is a common disease of the heart. Tricuspid Regurgitation is underdiagnosed and undertreated. We’re changing that. The DUO™ System is tailored to each patient and each heart.
Our collective mission.
It’s estimated that over 4 Million people in the US and Europe alone suffer from tricuspid regurgitation1,2. Our goal is to support more hearts, preserve native anatomy, shorten the learning curve for practitioners, and extend more lives.
“
Nature has designed this wonderful structure that beats throughout life and it’s very important that we assist it to function. That’s what the DUO does, it assists the native tricuspid valve to function as it should.
