The life of congenital heart disease ventricular septal defect does not have an accurate figure in the clinic, the specific survival period and the size of the defect, whether the active treatment and treatment time, whether the standardization of post-surgical care, etc. are related. 1. congenital heart disease ventricular septal defect size: for patients with a small defect, generally do not need special treatment, can not be operated on, the prognosis is very good, survival time will not be affected, if the defect is very large and without standardized treatment of patients will generally die because of severe heart failure and other complications, generally die at the age of about 20 years. 2. Whether active treatment and treatment time: for patients who have been found to have ventricular septal defects need to be actively treated in a timely manner, active surgical treatment, the prognosis is better, clear fetal ventricular septal defects need to be operated as soon as possible after birth, early detection and early treatment. Early detection and early treatment. If the recovery is good, the patient’s life expectancy will not be affected. 3. Whether the post-surgery care is standardized: after surgery, you need to develop good dietary and living habits, rest as much as possible, try to eat as light as possible, etc., and have regular checkups, all of which can affect the survival period after surgery. Patients with congenital heart disease ventricular septal defects need to standardize their treatment under the guidance of their doctors, and actively cooperate with them to prolong their survival period as much as possible.
