We fight with all our hearts...
Whom do you help?


Big heart to small heart is a non-profit, humanitarian association of doctors, health staff and parents of children who have congenital heart defects or other heart diseases. It was founded in 1994. in Zagreb and it is one of the oldest associations in Croatia.

There are currently over 10,000 children with heart disease in Croatia, and at least another 500 are born every year.

Speaking of children who suffer from congenital heart defects, it is inevitable to emphasize that their condition is incurable, that only with palliative care (surgeries), medications and constant supervision, and that they can live like healthy children only to a certain extent. In our association, children with cardiovascular diseases are considered little warriors, who are involved in a a major fight for life and who are, from birth ( and before), children with special needs.

The association's main goals are developing consciousness about the necessity of early identification of heart defects and fundraising for necessary appliances, medication and other tools.
