It is now expected that greater than 90% of children born with CHD will survive to adulthood (Figure 1-1). Consequently, in the United States, there are now greater than 1 million adults with congenital heart disease (ACHD), with a 5% increase or 20,000 new patients reaching adulthood each year (Figure 1-2). In fact, it is estimated that for the first time in history, there has been a shift in the CHD population (Figures 1-3A, 1-3B, and 1-3C) with more adults living with CHD than children (Figure 1-4)2.
