The event On Tuesday 8th November at the Grammar School at Leeds, a group of Horsforth School students in Year 7 will be swimming for up to 45 minutes in a stroke of their choice to raise vital funds for Children's Heart Surgery Fund. About CHSF Congenital heart disease is the most common birth defect in the world, with 1 in 100 babies being born with a congenital heart defect in the UK. Childrens Heart Surgery Fund (CHSF) support the Leeds Congenital Heart Unit (LCHU) as a world-class centre of excellence - by providing the funding and resources needed to care for a patient's heart, mind, family and future. CHSF are wholly funded by public donations, and because of YOU, the LCHU are able to give the best treatment to 17,000 babies, children, teenagers and adults living with congenital heart disease in our region each year.
