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.

Causes of hoarseness due to ventricular septal defect.

If a patient exhibits some ventricular septal defects, it is possible for hoarseness to occur, as this condition is a type of congenital heart disease. If a patient frequently experiences hoarseness, it might be caused by congenital heart disease, but chronic pharyngitis or laryngitis, which can also cause hoarseness, should not be ruled out. Additionally, conditions like vocal cord polyps or deeper diseases can lead to hoarseness. However, it is important to differentiate these from normal diseases. If the issue is solely a ventricular septal defect, surgical treatment can be recommended for the patient, which can achieve a complete cure. Attention should also be paid to maintaining a healthy diet.

What are the complications of ventricular septal defect?

The complications of ventricular septal defect mainly include the following: 1. Causes infective endocarditis, with the highest incidence occurring between the ages of 15 and 29; 2. Leads to aortic valve insufficiency; 3. Causes conductive blockages; 4. Leads to heart failure, and can even lead to Eisenmenger syndrome. Therefore, patients with ventricular septal defects should actively complete examinations such as echocardiography. If there are indications for surgery, they should promptly visit a cardiac surgeon for active surgical treatment to correct the anatomical abnormalities of the ventricular septal defect and prevent the condition from worsening and leading to serious consequences.

Ventricular septal defect is what?

Ventricular septal defect is a common congenital heart disease, mainly due to the abnormal defect in the ventricular septum during the fetal development, resulting in an abnormal channel between the left and right ventricles. Ventricular septal defect can cause blood to shunt from the left ventricle to the right ventricle, gradually increasing the blood flow in the pulmonary circulation, leading to an increase in the volume load of the left and right ventricles, while causing a decrease in the systemic circulation volume. In the later stages, due to the significant increase in right ventricular pressure, it leads to right-to-left shunting, thereby causing Eisenmenger's syndrome. For ventricular septal defects with a large degree of defect, timely interventional treatment or surgical ventricular septal defect repair is required.

Is ventricular septal defect related to premature birth?

Generally, premature birth is not related to ventricular septal defect. Although a premature infant is born early, their heart structure, lungs, and other body structures are normal. Ventricular septal defect is often caused by a developmental disorder of the septum during the fetal period, manifesting as left-to-right or right-to-left shunting. Generally, patients with a simple ventricular septal defect can survive normally. They can be completely cured through interventional treatment or surgical surgery, so there is no need to worry excessively. There is no direct connection between ventricular septal defect and premature birth.

What should I do about hypoxia due to a ventricular septal defect?

Mild ventricular septal defects generally do not cause hypoxia. If symptoms of hypoxia recur due to a ventricular septal defect, it is recommended to undergo minimally invasive interventional treatment or surgical treatment at a hospital to prevent further episodes. The success rate of this surgery is very high, almost 100%, with relatively few complications. If hypoxia occurs in untreated ventricular septal defects, initial therapy should include oxygen administration, followed by diuretic, cardiotonic, and other treatments to reduce cardiac load at a hospital, and surgery should be considered as soon as suitable.
