A mild atrial septal defect, such as one smaller than 3mm, allows for a normal life without any impact. In fact, some people only discover this condition during medical exams in their seventies or eighties. Therefore, it is safe for these individuals to travel to high altitudes. However, a larger atrial septal defect often causes symptoms like tightness in the chest, palpitations, and difficulty breathing after hypoxia or intense exercise. These patients have poorer compensatory abilities and are advised against going to high altitudes to avoid high altitude sickness. If such patients need to go to high altitude, it is recommended that they consider surgery before doing so.

Does a ventricular septal defect make it easier to catch a cold?

Mild atrial septal defects generally permit a normal life and do not easily cause colds. However, when pulmonary hypertension and heart failure occur with an atrial septal defect, it can lead to pulmonary congestion. At this point, bacterial colonization occurs, making respiratory infections more likely to develop. However, the colds we often refer to are upper respiratory tract infections, and atrial septal defects generally do not cause a decrease in immune system function. However, if the upper respiratory tract infection is not treated promptly, it can lead to bronchitis, lung infections, etc., often exacerbating heart failure associated with the atrial septal defect. Therefore, while an atrial septal defect does not cause colds, patients with an atrial septal defect should address colds early to prevent the onset of heart failure triggered by the cold.

Is a ventricular septal defect with pulmonary hypertension mild or severe?

The most common complication of atrial septal defect is pulmonary hypertension, which can be classified as mild, moderate, or severe. Generally, mild pulmonary hypertension is not a major issue and is not considered very serious. However, moderate to severe pulmonary hypertension often accompanies repeated coughing, shortness of breath after exercise, or difficulty breathing. This situation is relatively serious and it is advisable to undergo surgery as soon as possible. If the condition reaches a severe stage, pulmonary hypertension could continuously increase. Furthermore, in patients with severe pulmonary hypertension, closing the atrial septum can lead to severe breathing difficulties and increased shortness of breath. Therefore, it is crucial to closely monitor patients with pulmonary hypertension.

How severe is an atrial septal defect considered to be?

Atrial septal defect (ASD) is a relatively common congenital heart disease in clinical practice. From a medical perspective, the severity of ASD depends on whether the patient is an adult or a child. For adults with ASD, generally speaking, defects larger than 20 millimeters are considered large atrial septal defects, which are more severe. If the defect size is between 10 and 20 millimeters, it is often classified as a moderate atrial septal defect. Defects smaller than 4 millimeters are considered small atrial septal defects. Generally, small and moderate atrial septal defects are not severe. For children, an atrial septal defect larger than 10 millimeters is considered a large atrial septal defect, which is more severe. Sizes between 5 and 10 millimeters are classified as moderate atrial septal defects. Defects smaller than 5 millimeters are considered small atrial septal defects, which generally are not severe.

How does septal defect shunt?

Atrial septal defect is the most common congenital heart disease in adults, accounting for 20%-30% of all adult congenital heart conditions. The impact of an atrial septal defect on hemodynamics primarily depends on the amount of shunting. Due to higher pressure in the left atrium compared to the right atrium, a left-to-right shunt is formed. The amount of shunting depends on the size of the defect, as well as the compliance of the left and right ventricles and the relative resistance in the systemic and pulmonary circulations. Diseases that affect the compliance of the left ventricle, such as hypertension and coronary artery disease, can increase the extent of the left-to-right shunt. A continuous increase in pulmonary blood flow leads to pulmonary congestion, increasing the load on the right heart. Pulmonary vascular compliance decreases, progressing from functional pulmonary arterial hypertension to organic pulmonary arterial hypertension. As right heart system pressure continuously increases and eventually exceeds the pressure in the left heart system, the original left-to-right shunt reverses to become a right-to-left shunt, resulting in cyanosis.

Symptoms of an infant's room septal defect

Symptoms of ventricular septal defect in infants are as follows: 1. Symptoms: If the mother had intrauterine infections within the first three months of pregnancy, was exposed to significant amounts of radiation, took teratogenic medications, or had metabolic disorders, these factors could contribute to the condition. The patient is prone to recurrent respiratory infections and exhibits symptoms of palpitations, shortness of breath, fatigue, and excessive sweating. If these symptoms worsen after physical activity or crying and are accompanied by cyanosis, congenital heart disease should be considered. Cyanosis can intensify during severe crying episodes, pneumonia, or heart failure in infants, and may be accompanied by a hoarse voice. 2. Physical signs: Notable findings include a bulging in the precordial area and diffuse apical impulse. A soft, systolic murmur can be heard between the second and third ribs along the left margin of the sternum.
