In collaboration with specialists in cardiology from the CHUV in Lausanne, every year we organize two surgical missions to Dakar. These assignments have the purpose of consultation, care and surgery of sick children in their own country, whilst strengthening the skills of the local staff. The Chain of Hope, an NGO with whom we work on the ground, has set up the Cuomo Centre, a division for paediatric heart surgery within the Fann University Hospital Centre in Dakar. This major advance makes it possible to increase the number of children operated on in their own country.
