Atrial septal defect
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.
Can someone with atrial septal defect travel by airplane?
Atrial septal defect is a relatively common congenital heart disease in daily life. Many patients with atrial septal defect often ask if they can fly on planes. This depends on the specific condition. If the atrial septal defect is combined with severe cardiac damage, such as heart failure, then flying is definitely not allowed. However, if the atrial septal defect is mild, not severe, without clinical symptoms or cardiac damage, then it is indeed possible to fly. It is recommended for those in this condition to visit a cardiology outpatient clinic at a hospital and ask a doctor to make an assessment.
Can a ventricular septal defect have a vaginal delivery?
Atrial septal defect is a relatively common congenital heart disease in adults. Therefore, when women are diagnosed with this condition, they often ask their doctor one question: "Can I give birth naturally?" This question requires a case-by-case analysis. If the atrial septal defect is not severe, does not cause changes in the heart structure, or lead to heart failure, then natural childbirth is definitely possible. However, if the atrial septal defect is severe and causes changes in heart structure, such as pulmonary hypertension or heart failure, then natural childbirth is generally not advisable. It is best to opt for a cesarean section under the guidance of a doctor to alleviate the burden on the pregnant woman and reduce the occurrence of serious incidents.
