It’s estimated that in the next few years one in 150 adults could have congenital heart disease (CHD).And two-thirds of those who have CHD are adults , according to a recent Canadian study. It is now know that problems can occur years after CHD repair and that ongoing cardiology follow-up can prevent or detect serious complications. But many patients whose CHD was repaired in childhood have not had regular cardiology follow-up. Indeed, many patients with CHD or with complications of CHD repair come to medical attention only by way of noncardiac care settings.
