Congenital heart disease is a malformation of the congenital heart that can lead to hemodynamic disturbances. Simple congenital heart malformations have little impact on the patient’s life expectancy after surgery, but certain severe congenital heart diseases have a greater impact on the function of the heart, even with surgery, and have some impact on life expectancy. Therefore, if the condition of congenital heart disease is diagnosed, one needs to go to the hospital promptly for tests including electrocardiogram, cardiac ultrasound, coronary CTA, coronary angiography, and nuclear myocardial imaging. These can determine the type of congenital heart disease and the extent of the malformation, and can assess the next step in treatment. Cardiac stimulants and diuretics are also required to improve cardiac function after the procedure.
