A less invasive examination for atrial tachycardias after surgery for congenital heart disease.

he clinical results of corrective surgery for congenital heart disease have dramatically improved during the past quarter of a century. As a result, many children who have undergone cardiac surgery in their childhood have now grown up to adults. These patients often have morbidities related to the congenital disease and surgeries they received (adult congenital heart disease).
