Because ventricular septal defect is a type of congenital heart disease, it is currently recommended that patients undergo surgical treatment. With active treatment, this disease can be cured. Once cured, the patient's symptoms will subside, and no murmur can be heard in the precordial area, and it is possible to choose to have children in this situation.

If this condition is not dealt with promptly, it is not recommended to have children. This is because it can cause an excessive load on the heart, especially when the blood volume increases, leading to occurrences of ischemia and hypoxia, which are very dangerous. If treated, especially within a year after surgery, it is possible to consider having children, but there are certain risks.

Will being overweight affect the surgery for a ventricular septal defect?

Ventricular septal defect surgery is performed by puncturing the right femoral vein, guiding the catheter into the inferior vena cava, through the atria and ventricles, and reaching the defect via the right ventricle. The occluder can then be delivered through the catheter into the left ventricle, where the umbrella is opened, followed by opening it in the right ventricle; this describes the surgical process. Therefore, generally speaking, the surgical process is not affected in most patients who are obese. However, severe obesity can impact the accuracy of vascular localization during puncture by the surgeon. Secondly, if complications such as anesthesia issues or other emergencies arise during the surgery, severely obese patients may experience a reduced success rate in emergency surgical interventions, hence it is recommended that patients control their weight. Furthermore, severe obesity can exacerbate the cardiac load originally induced by the ventricular septal defect, thus affecting the surgical tolerance in patients whose cardiac function is already compromised by the defect. It is recommended that these patients control their weight.

What are the symptoms of ventricular septal defect?

What are the symptoms of a ventricular septal defect? In normal individuals, there are no defects between the ventricular septa. However, if there is a small ventricular septal defect, such as less than five millimeters, typically ranging between two to three millimeters, this minor defect functions like small gaps between normal windows and doors, causing minimal shunting which generally does not significantly impact the patient, resulting in no obvious symptoms. However, if the defect is relatively large, such as exceeding five millimeters, causing significant left ventricular blood to shunt to the right ventricle, it can lead to congestion in the right ventricular system or pulmonary circulation. Under such conditions, patients may frequently experience respiratory infections, congestive heart failure, or in children, reluctance to eat, presenting feeding difficulties and developmental delays. Of course, if the defect continues to enlarge, achieving a size larger than the patient's aorta, the patient may show signs of significant right heart failure due to the damaged ventricular septum, necessitating emergency surgical intervention.

Can an 8mm ventricular septal defect heal by itself?

The ventricular septal defect is 8 millimeters, which is considered a medium-sized defect. This type of defect is relatively large and will not heal on its own. Moreover, this ventricular septal defect requires timely surgical treatment, and close observation is needed in daily life. If the child is prone to catching colds, leading to repeated pneumonia, then prompt surgical treatment is necessary without delay. If the child's growth and development are not affected and there are no repeated incidents of pneumonia, close monitoring can be considered. Surgery to repair the ventricular septal defect can be considered after the child reaches two years of age. Otherwise, if delayed, it may lead to heart failure and complications such as pulmonary hypertension, severely affecting the quality of life and endangering the patient's safety.

If a ventricular septal defect is not surgically repaired, what will happen?

If the patient has a history of congenital heart disease, especially ventricular septal defect, it can lead to symptoms such as palpitations and chest tightness. The current recommendation for treatment is primarily symptomatic management; however, it is also advised that patients seek early surgical intervention at a hospital. Medical treatment or drug therapy often does not yield ideal results for this condition, and surgical intervention is necessary to address these symptoms. Currently, minimally invasive surgical treatment can be used. If the patient does not undergo surgery, conditions such as palpitations, chest tightness, and difficulty breathing can occur at any time.

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.
