Exhaustive in its scope, this book provides a comprehensive study of the natural and modified history of congenital heart disease. Focusing particularly on the discussion of fetal and post-natal outcomes, the contributors seek to place developments in historical perspective. Virtually all surgical and catheter-based strategies to enhance outcomes of all forms of congenitally malformed heart are analysed, covering the morphology and genetic basis of each particular abnormality, and issues that were germane to evolving different therapeutic strategies. Using data from the records of the Toronto Hospital for Sick Children, contributors highlight the complications of the various forms of therapies and identifies particular risk factors for mortality and morbidity.
