This December Issue of Cardiology in the Young represents the 13th annual publication in Cardiology in the Young generated from the two meetings that composed “HeartWeek in Florida”. “HeartWeek in Florida”, the joint collaborative project sponsored by the Cardiac Centre at the Children’s Hospital of Philadelphia, Philadelphia, Pennsylvania, together with Johns Hopkins All Children’s Heart Institute of Saint Petersburg, Florida, averages over 1000 attendees every year and is now recognised as one of the major planks of continuing medical and nursing education for those working in the fields of diagnosis and treatment of cardiac disease in the foetus, neonate, infant, child, and adult. “HeartWeek in Florida” combines the International Symposium on Congenital Heart Disease, organised by All Children’s Hospital and Johns Hopkins Medicine, and entering its 16th year, with the Annual Postgraduate Course in Paediatric Cardiovascular Disease, organised by The Children’s Hospital of Philadelphia entering its 19th year.
