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.

What should be noted for an atrial septal defect with patent foramen ovale?

If the patient presents with a ventricular septal defect or a patent foramen ovale, it is important to maintain a healthy diet and particularly to prevent upper respiratory infections, as these conditions are types of congenital heart disease. They mainly lead to repeated respiratory infections, cyanosis, or lung infections, resulting in changes associated with congenital heart disease. For a ventricular septal defect, early surgical intervention is currently recommended. Patent foramen ovale is also treated surgically. During this period, it is important to monitor changes in the child's height and weight, as such diseases can affect the child's growth and development.

Interventricular septal defect X-ray manifestation

X-ray Manifestations of Ventricular Septal Defect. These are mainly related to the size of the defect. If the ventricular septal defect is relatively small, for example less than three millimeters, the amount of blood shunted from the left ventricle to the right ventricular system is minimal. Consequently, right ventricular congestion is not pronounced, making pulmonary congestion also less obvious. At this point, the X-ray may show no significant changes. However, if the defect is larger, greater than three millimeters, for instance five millimeters, a large volume of high-pressure blood from the left ventricle will flow excessively through the defect into the right ventricular system. This leads to significant congestion in the right ventricle and, thus, in the entire pulmonary circulation. Additionally, the X-ray will show a prominent pulmonary artery segment and increased pulmonary blood flow. Moreover, over time, this condition may lead to compensatory enlargement of the left ventricular system. On the X-ray, enlargement of both the right and left ventricles can be observed. Furthermore, due to sustained high pressure, the distal pulmonary arteries may show signs of severe pulmonary vascular disease on the X-ray, resembling a broken book. This indicates that the pulmonary circulation has reached an end-stage condition.

Does a ventricular septal defect easily cause hiccups in infants?

The relationship between the two is not very significant. A ventricular septal defect is a type of congenital disease, and currently, surgical treatment is recommended for patients, as medical treatment is not very effective and prone to relapse. For this type of congenital heart disease, it is best to first perform a cardiac echocardiography to make a clear diagnosis. In terms of treatment, early surgical intervention is suggested for patients to thoroughly improve symptoms such as palpitations, chest tightness, and difficulty in breathing. If an infant often experiences hiccupping, it could be a sign that the infant's stomach is not very mature, leading to excessive stomach acid, but this is not significantly related to the ventricular septal defect.

Can people with ventricular septal defect swim?

If the patient has a ventricular septal defect, swimming can lead to ischemia and hypoxia, and thus, it is not advisable for the patient to swim. If symptoms such as palpitations or breathing difficulties occur, this can be very dangerous, and I would personally advise against going into the water. It is also crucial to actively treat this congenital heart disease. I suggest that the patient should undergo a cardiac echocardiography at a hospital for a clearer diagnosis. Currently, the treatment mainly focuses on symptomatic treatment, and it is recommended that the patient considers surgical options to alleviate the suffering and improve the condition. During this period, attention should also be paid to a healthy diet, especially avoiding spicy and stimulating foods.
