1% of children are born with congenital heart defects. And among them, the severe and complex univentricular hearts.

The last decades, surgical techniques have improved and so have the outcomes. Nowadays, 70 000 patients live with the Fontan circulation.

David dedicates his life to find solutions for these patients. Last year, his daughter was born with Hypoplastic Left Heart Syndrome. It requires 3 open heart surgeries before 3 years old. Proper breathing was seen as an important factor for life expectancy and quality of life.

At the moment, he is focusing exclusively on this issue.
