Atrial septal defect symptoms?

summary

Atrial septal defect (ASD) may be very common in cardiovascular department, but as ordinary people, we may not know much about it. There are not many cases of ASD in our daily life. Even if many people have some symptoms of ASD, they don't know they are ASD. Let's understand the symptoms of ASD?

Atrial septal defect symptoms?

Most of the symptoms of ASD are not consistent, which is closely related to the size of ASD and the amount of shunt. The symptoms appeared earlier in patients with large defect; The patients with small defect may have no symptoms for a long time and remain latent until old age. Most of the cases were asymptomatic in childhood, and were often found in physical examination; Generally, symptoms begin to appear at the age of 21-40.

In infant cases, the pulmonary circulation resistance is still high after birth, so if the defect is huge, a small amount of blood may flow from right to left, resulting in mild cyanosis. A few months after birth, the pulmonary circulation resistance gradually decreases, and the pressure of right atrium is also lower than that of left atrium. Cyanosis disappears immediately because the blood system flows from left to right. But in the late stage of the disease, when the blood turned to countercurrent (from right to left), cyanosis appeared to a certain extent, and continued to worsen until death.

Because of pulmonary congestion, children are prone to recurrent severe pulmonary infection, manifested as cough, shortness of breath, and even pneumonia. Due to the decrease of left ventricular blood flow, most patients are lack of physical strength, prone to fatigue and dyspnea. It is easier to feel shortness of breath and palpitation after work. In addition, the long-term existence of right heart diastolic overload may lead to pulmonary hypertension and right heart failure. But its evolution is relatively slow, which can be extended for several years.

matters needing attention

The harm of atrial septal defect is very great. We should pay attention to it. We should find and treat it early. The earlier the treatment, the better the effect. In daily life, we should also do a good job in preventing the disease of atrial septal defect, actively do a good job in prenatal examination, give up bad living habits, and let the children grow up healthily.
