What are we fundraising for?

Sweetheart Day is our annual flagship event held on February 14 - International Congenital Heart Defect Awareness Day (aka Valentine’s Day). During February we are raising awareness and funds to support the 8 babies every day born with a heart defect. That is one every 3 hours when a families lives change in a heartbeat.

Sadly 4 young lives are lost to CHD each week. Sweetheart Day is your chance to join in the fight against this disease.

This February we are raising awareness of the impact that congenital or childhood acquired heart disease has on families.
