Atrial septal defect 6mm is dangerous

ASD 6 mm is usually hazardous, may increase atrial level left-to-right shunt, pulmonary hypertension, arrhythmia, infection risk, affect growth and development, need to be checked regularly, according to the specific situation evaluation and treatment plan. ASD 6 mm is usually hazardous. Atrial septal defect (ASD) is a common congenital heart disease. It is caused by the abnormality of the original atrial septum during embryonic development, which leads to the incomplete fusion of the septum between the left atrium and the right atrium. 6 mm ASD, although not usually causing severe symptoms, may present the following hazards: Increased atrial horizontal left-to-right shunt: ASD causes partial flow of blood from the left atrium into the right atrium, increasing the volume load on the right atrium. Long-term left-to-right shunt may cause enlargement of the right atrium and ventricle, affecting cardiac function. Pulmonary hypertension: Pulmonary artery pressure may gradually increase over time due to prolonged left-to-right shunting. If pulmonary artery pressure continues to increase, pulmonary valve insufficiency may occur, further burdening the heart. Arrhythmia: atrial septal defects may increase the risk of arrhythmia, such as atrial fibrillation. Infection risk: Atrial septal defect causes shunt between atria, which is easy to cause systemic infection, especially lung infection. Impairment of growth and development: In children, atrial septal defect may affect growth and development, resulting in low height, weight and other developmental indicators. However, each patient is unique, and the risk of an atrial septal defect is influenced by other factors, such as age, cardiac function, and other cardiac diseases. Therefore, patients with an atrial septal defect of 6 mm need regular cardiac ultrasound to monitor changes in cardiac structure and function. Your doctor will assess your risk on a case-by-case basis and plan treatment accordingly. Small ASDs may not require immediate treatment but regular observation. Large ASDs or patients with significant symptoms may require interventional closure or surgery to close the ASD and restore normal heart structure and function. In summary, ASDs 6 mm do not usually pose an immediate serious hazard, but they require close attention and regular follow-up. Patients should follow their doctor's advice for appropriate examinations and treatment to maintain heart health. If there is any doubt about ASDs or other heart conditions, it is recommended to consult a specialist cardiologist.
