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.

Symptoms of ventricular septal defect

The main symptoms of a ventricular septal defect depend on the size of the defect and the age of the patient. Generally, smaller ventricular septal defects, such as those measuring only one to two millimeters, result in very little shunting from the left ventricular system to the right ventricular system. This is akin to a tiny amount of air seeping through a crack in a window or door. In such cases, the patient typically does not exhibit noticeable symptoms. However, if the defect is larger, over five millimeters, a significant amount of blood passes from the left ventricular system into the right ventricular system, which can cause substantial congestion in the right or both lungs of the right ventricular system, or lead to recurrent respiratory infections and congestive heart failure. The affected individual may show disinterest in eating, feeding difficulties, and delayed development. As the patient grows older, they may exhibit reduced activity endurance, fatigue or palpitations, and shortness of breath. Gradually, cyanosis and right heart failure may develop. Additionally, patients are at risk of developing infective endocarditis, fever without symptoms, and recurring fever.

Is it necessary to perform amniocentesis for a ventricular septal defect?

Ventricular septal defect generally is not hereditary, and its genetic DNA should not be problematic. Therefore, the amniocentesis for patients with ventricular septal defect could potentially be problem-free. Although amniocentesis is not very diagnostic, it is still recommended for older patients or those with high risks of malformations or genetic variations. If there is only concern about a ventricular septal defect, a four-dimensional color Doppler ultrasound can be performed. Particularly after the 22nd week of pregnancy, a four-dimensional cardiac ultrasound can help in identification. However, some very small defects might not be detectable. But typically, a minor, isolated ventricular septal defect might impact heart function but generally does not significantly affect the growth and development of the child.

Can ventricular septal defect avoid amniocentesis?

Because ventricular septal defect is a type of congenital heart disease, it is recommended that patients adopt a light diet and especially avoid spicy and stimulating foods due to the condition of ventricular septal defects. It is still recommended to pursue active and early surgical treatment to improve symptoms. If there is poor cardiac function, or symptoms of palpitations and chest tightness occur, amniocentesis should not be performed as it carries certain risks. However, for milder symptoms that can be timely controlled, amniocentesis and other tests may be considered, but it is also necessary to rule out other diseases. If the patient does not have any special diseases in the past, such as coronary heart disease or diabetes, the procedure can be handled.

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.

Why does a ventricular septal defect cause respiratory infections?

Because ventricular septal defect is a type of congenital heart disease, it mainly leads to pulmonary infections in children, often causing respiratory infections. If this condition is not treated in time, it can worsen the symptoms, decrease the child's resistance, and lead to frequent respiratory diseases. Early surgical treatment is recommended to improve the child's symptoms. It is also important to monitor the child's breathing, heart rate, and pulse changes, and it is advisable to regularly revisit the hospital for an echocardiogram. Early surgical treatment is recommended as it can completely cure the disease.
