I'm setting myself a sporting challenge

"On Route 66, for a month and a half, and during those 3581 km by bike, I often put my knee to the ground. But thanks to the active participation of my donors, I never doubted that we would succeed in saving a child. What a wonderful victory and, above all, what a wonderful feeling!"
I'll take a number sign
Running or cycling with a charity bib number means choosing to take on a charitable challenge in addition to the sporting challenge: saving children awaiting heart surgery. You will be supported throughout your fundraising efforts right up to the day of the event and will receive a "Coureurs du Cœur" T-shirt to proudly wear the Association's colors.
Paris-Roubaix Challenge
Tackle the cobblestones of the Hell of the North with your heart for cardiac children.
L'Étape du Tour de France and L'Étape du Tour de France Femmes

The Schneider Electric Marathon de Paris
With a solidarity number sign, running is no longer just an individual performance, but a challenge in aid of children with heart disease.
I collect for a personal occasion
Join our large family of Collecteurs du Cœur and make your special occasions a unique moment of solidarity for the world's children.
- Moments in life: To celebrate a birth or a wedding, to pay tribute to a loved one or to celebrate retirement, create a collection to make the most memorable moments unforgettable!
- Birthday: Collect donations rather than gifts by dedicating your birthday to children with heart disease.
- Events: Are you organizing a concert or a sale? Any occasion is a good opportunity to raise funds!

I collect as a heart family

By naming their project "À Coeur Joie", the De la Ville family set the tone. For several months, they redoubled their energy, good humor and dynamism on social networks to mobilize their entourage and grow their online collection. They finally achieved their goal: to raise €12,000 to finance medical care for Lucas, a one-and-a-half-year-old boy from Cameroon whom they then took in.

Why create a fundraising page for Mécénat Chirurgie Cardiaque ?
Worldwide, 1 in 100 children is born with a heart defect. Cardiac surgery is often the only way to save these children. By donating to Mécénat Chirurgie Cardiaque, you'll be helping children benefit from life-saving surgery, and giving your project that extra touch of solidarity that's been missing to make it magical!
-
What is my fundraising campaign for? How are donations used?
Donations made by friends and family on our fundraising pages are donated in full to Mécénat Chirurgie Cardiaque to finance our missions. To find out more about how donations are used, please visit this dedicated page.
-
What happens if I don't reach my fundraising target?
With the exception of solidarity number signs, the fundraising target is free. It is therefore always possible to change it during the course of your fundraising campaign.
Whatever the amount raised, whether it exceeds or falls short of your target, all donations will be used to finance a child's operation.If you reach the symbolic amount of €12,000, you will finance the medical care of a child with a heart condition.
