Once the diagnosis of congenital heart disease is clear, it is recommended to complete the surgery in early childhood, or even in infancy. Therefore, in case of congenital heart disease, the first step is to go to the hospital and observe the degree of malformation and the heart function according to the heart ultrasound, ECG and coronary CT. Most of the congenital heart diseases need to be corrected surgically, through which the heart is restored to its normal structure, so that the life expectancy is the same as that of a normal person. Some patients also need to take cardiotonic and diuretic drugs after surgery, such as digoxin, spironolactone, hydrochlorothiazide, etc., so as to maximize the recovery of the patient’s heart function. Regular review is also required to clarify the dosage increase or decrease according to the results of the review.
