Because a ventricular septal defect is a type of congenital heart disease, if surgery is not performed, it can sometimes lead to ischemic and hypoxic conditions in patients. During this period, active surgical treatment is still necessary, as this disease primarily relies on surgical intervention. Medical treatment, especially drug therapy, is not very effective, so it is recommended to prioritize immediate treatment with surgical assistance.

After surgery, it is still necessary to regularly check the heart with an echocardiogram, as this disease can produce murmurs in the precordial area. Patients may also experience recurring respiratory infections, especially cases of bronchitis and bronchopneumonia.
