A conference was held in Edinburgh to discuss the best way to reduce the number of young people dying suddenly from heart defects.
Campaigners are calling for all children in Scotland to be screened, but others caution that mandatory testing would be costly and not pick up on all cardiac problems.
The campaign for heart screening has been reignited after last month's collapse of Bolton midfielder Fabrice Muamba from a cardiac arrest. The 24-year-old remains in hospital - his condition improving slowly.
In 2008, the Scottish Government announced athletes aged 16 and over would be given a cardiac assessment. However some say that this does not go far enough.
21-year-old Andrew Murch died in his sleep five years ago and his mother and father want screening to be available to all young people.
Scotland Tonight spoke to Andrew Murch's parents Hazel and Gordon, and the cardiologist Dr Iain Findlay.
