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.

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.

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.

Can someone with a ventricular septal defect travel by airplane?

Generally, individuals with ventricular septal defects (VSD) with no complications do not display symptoms and are able to travel by airplane. When such defects are at an early stage, where cardiac function has not been significantly impaired and there is left-to-right shunting without heart failure or pulmonary hypertension, flying is generally tolerated. After surgery for a ventricular septal defect, patients usually can fly. However, if the patient with a ventricular septal defect is older and in the advanced stages of the condition, exhibiting clear symptoms of heart failure such as difficulty breathing and chest tightness with significant exertional stress, such patients are unable to lie down and should not fly. Additionally, if there is right-to-left shunting or severe pulmonary hypertension has developed, it is unsafe for them to fly as they could potentially face emergencies during the flight.

Does a ventricular septal defect affect development?

Does a ventricular septal defect affect development? For relatively small ventricular septal defects, such as those under five millimeters, the shunt from the left ventricle to the right ventricle is minimal, hence patients may not exhibit noticeable symptoms. However, if the defect is larger, for instance, over five millimeters, a large volume of blood will flow from the left ventricle into the right ventricular system. This causes congestion in the right ventricular system and the pulmonary circulation will be flooded with blood. As the saying goes, "flowing water does not rot, nor do door hinges become worm-eaten"; however, when a large amount of blood accumulates in the pulmonary vessels, patients are prone to recurrent respiratory infections and even congestive right heart failure, which then leads to feeding difficulties. Patients feel consistently uncomfortable and have difficulty breathing, so they may be reluctant to eat, especially in young children who need considerable effort to drink milk, which requires some breath-holding. At this time, patients experience feeding difficulties, which equates to developmental delays. Therefore, larger ventricular septal defects can affect a child's development. Small defects, such as those under three millimeters, might not affect development, but larger defects do impact development and thus require timely treatment.

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.
