Introduction: A lifelong interdisciplinary approach to common arterial trunk, transposition of the great arteries, and other evolving challenges in paediatric and congenital cardiac disease.

This December issue of Cardiology in the young represents the tenth annual publication generated from the two meetings that compose "HeartWeek in Florida". "HeartWeek in Florida", the joint collaborative project sponsored by the Cardiac Center at the Children's Hospital of Philadelphia, together with All Children's Hospital of Saint Petersburg and Johns Hopkins Medicine, averages over 1000 attendees every year and is now recognized 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 fetus, 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 13th year, with the Annual Postgraduate Course in Pediatric Cardiovascular Disease, organised by The Children's Hospital of Philadelphia and entering its 17th year. The theme of this supplement generated from the 2012 HeartWeek in Florida is "A Lifelong Interdisciplinary Approach to Common Arterial Trunk, Transposition of the Great Arteries, and Other Evolving Challenges in Paediatric and Congenital Cardiac Disease". We would like to acknowledge the tremendous contributions made to medicine by Richard Jonas; and therefore, we dedicate this HeartWeek 2012 Supplement to him.
