The incidence of Congenital Heart Disease (CHD) in live new-borns is estimated to vary from 4.1/1000 to 12.3/1000. The improvement in survival of CHD patients has led to burgeoning numbers of grown-up CHD.The majority of these CHD patients face a lifetime of problems including RV dilation, ventricular arrhythmias, and sudden cardiac death.Considering inflation to visit costs and added image technology for diagnosis, the cost of each patient is expected to increase .In contrast to adult patients with acquired heart disease, abnormalities of the RV are ubiquitous in children and adults with CHD.
