Since patent ductus arteriosus is a congenital heart disease, it is recommended that patients have regular echocardiographic re-examinations. For the majority, this condition can close on its own. However, if it does not close, surgical treatment is necessary.

Currently, the patient's patent ductus arteriosus has reached about 8 millimeters, which is quite severe. It is advised to seek early surgical treatment at a hospital to alleviate the symptoms. Presently, there are no medications available to treat this disease, and surgical treatment is the primary approach. Early surgical intervention at a hospital is advisable.

Is it easy to get pneumonia if the arterial duct is not closed?

Because patent ductus arteriosus is a type of congenital disease, particularly congenital heart disease, it is recommended that patients visit a hospital for a cardiac ultrasound. This can help clarify the diagnosis and thus determine the treatment plan. A simple patent ductus arteriosus can sometimes close on its own. For those that do not close or are underdeveloped, surgical treatment can be used to alleviate the current condition. This is important because the disease can easily lead to pneumonia, especially recurrent respiratory infections. Sometimes, there may be developmental anomalies, particularly affecting the growth and changes in the child's height and weight. In these cases, early surgical treatment is still recommended.

Why does patent ductus arteriosus cause a decrease in diastolic pressure?

In patients with patent ductus arteriosus, since the aortic pressure is significantly higher than the pulmonary artery pressure throughout the cardiac cycle, there is continuous blood flow from the aorta into the pulmonary artery through the open duct, causing a left-to-right shunt. This increases the blood volume in the pulmonary circulation, causing dilatation of the pulmonary artery and its branches. The blood flow returning to the left heart system also increases, thereby increasing the load on the left heart and causing the left heart to enlarge. Due to the diastolic diversion of blood from the aorta to the pulmonary artery, the peripheral arterial diastolic pressure decreases and the pulse pressure increases.

Does a patent ductus arteriosus easily lead to bronchitis?

Patent ductus arteriosus can lead to bronchitis, as this condition can cause recurrent respiratory infections, particularly bronchitis and bronchopneumonia. This is a type of congenital heart disease, and it is recommended that patients undergo regular echocardiography, especially cardiac ultrasound. If the closure of the patent ductus arteriosus is delayed, early surgical treatment is required. This condition can sometimes affect the growth and development of children, and it mainly causes repeated respiratory infections, including bronchitis, particularly issues with pulmonary inflammation, which require early management.

Is patent ductus arteriosus related to pregnancy?

The ductus arteriosus is a vital conduit in the fetus during intrauterine life, connecting the blood from the placenta to the pulmonary artery and the aorta, enabling the placental blood to reach the aorta and supply blood to the entire body of the fetus. Usually, if the fetus is viable, there should be no issues, so the non-closure of the ductus arteriosus is not related to the pregnancy period. After the birth of the fetus, as the lungs expand and heart function changes, the ductus arteriosus will automatically begin to close. In the vast majority of infants, the ductus arteriosus will likely close after three months of birth. If it has not completely closed within one year, it is considered that the child has patent ductus arteriosus. Therefore, in most cases, patent ductus arteriosus is not related to the pregnancy period. There might be a small fraction of cases where it could be due to poor development during the pregnancy, preventing the timely closure of the ductus arteriosus; however, in most cases, it is unrelated to the pregnancy period.

Will patent ductus arteriosus increase with age?

Patent ductus arteriosus is a type of congenital heart disease, primarily treated through surgery. Early surgical intervention can completely cure this disease. However, as age increases, the symptoms of this disease can become more severe. Based on the patient's condition, it is recommended to undergo early surgical treatment at a hospital to alleviate the patient's suffering. As age increases, various organic diseases may emerge, which can sometimes affect a child's growth and development. During this period, it is advised that the patient regularly revisits the hospital for echocardiography checks and to also be cautious in preventing upper respiratory infections.
