Ventricular septal defect can lead to choking on milk, as it can cause pathological murmurs in children, especially prominent in the chest area, which is a type of congenital heart disease. Currently, early surgical treatment is recommended for these children. The choking on milk might be due to reasons related to the digestive system, but it is still somewhat related to the ventricular septal defect. It is also advised to eat smaller, more frequent meals to avoid choking or aspiration, which can lead to bronchitis or recurrent respiratory infections.

What would happen if the ventricular septal defect occluder dislodges?

An occluder generally works like two umbrella surfaces clamped over the orifice of the interventricular septal defect, achieving the method whereby tissue blood flow enters from the left side of the septum to the right side. Once an occluder dislodges, it can lead to a dangerous situation, as the occluder has a membrane that can easily get caught on the tendons of the mitral valve, causing severe mitral regurgitation; it can also get stuck at the mitral valve orifice, obstructing the outflow of blood; it may also lead to aortic valve insufficiency; if it gets caught in the major arteries, it can cause arterial embolism, leading to sudden death in the patient. Therefore, the dislodgement of an occluder is a very dangerous phenomenon.

What will happen in the later stage if a ventricular septal defect is not operated on?

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.

Does a ventricular septal defect easily cause pulmonary embolism?

Ventricular septal defect is a type of congenital heart disease. Currently, early surgical treatment is recommended for this disease, as it can lead to the formation of blood clots and easily cause pulmonary embolism. If pulmonary embolism occurs, this disease is very dangerous and can significantly impact human life. Therefore, early surgical intervention is the main approach. During this period, it is crucial to actively control the patient's blood pressure, heart rate, and pulse changes. At the same time, active and early surgical intervention should be carried out. If the defect area is large, it can also lead to heart failure, especially if murmurs are present in the precordial region, and it can easily cause palpitations, chest tightness, and breathing difficulties.

Does a ventricular septal defect require open chest surgery?

Ventricular septal defects (VSD) can generally be treated through interventional procedures. Normally, defects with a diameter smaller than 3mm do not require surgical treatment. If the diameter is greater than 3mm but less than 10mm, interventional treatment is often feasible. Another scenario involves the subarterial type of defect, which generally cannot be repaired via a catheter-based approach and requires open-chest surgery instead. Additionally, for very large defects, repair must be conducted through open-chest surgery. Thus, for VSD, there are two main treatment options. Specific decisions require echocardiography to analyze the size and location of the septal defect to determine whether open chest surgery is necessary. Generally, most cases can be resolved through minimally invasive interventional methods.

Ventricular septal defect refers to a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart.

A normal human heart is divided into four chambers: the left ventricle, right ventricle, left atrium, and right atrium. The circulation in a normal person involves venous blood entering the right atrium, passing through the mitral valve into the right ventricle. The right ventricle then contracts and pumps blood into the lungs. After exchanging gases and becoming oxygenated, the blood turns bright red. It then returns to the left atrium. From the left atrium, blood passes through the mitral valve back into the left ventricle, and then the left ventricle contracts and pumps blood throughout the body. Therefore, there is a thick wall between the normal left and right ventricles, known as the ventricular septum. If due to congenital heart disease or other reasons, a small hole appears in the ventricular septum, it is called a ventricular septal defect. If this defect is large, it necessitates active surgical treatment because if the defect exists, the pressure of the blood flow in the left ventricle is higher, causing a large amount of abnormal blood to enter the right ventricle. This leads to a significant accumulation of blood in the right ventricle, causing the patient to have too much blood in the pulmonary circulation, making the patient prone to recurrent colds and infections. Furthermore, these children may easily develop heart failure and even life-threatening conditions such as infective endocarditis.
