Patent ductus arteriosus is a type of congenital heart defect. Typically, the ductus arteriosus is expected to close on its own, but if it remains open over time and is larger than about five centimeters, it is crucial to seek surgical treatment at a hospital promptly. Currently, there are no particularly effective medications to improve this condition since it is a congenital heart disease. Early surgical intervention is recommended. This condition is considered serious, and during this period, it is important to actively prevent upper respiratory infections, as they can repeatedly lead to pulmonary inflammation.

Is surgery necessary for an unclosed arterial duct?

Patent ductus arteriosus is a type of congenital heart disease. Currently, surgical treatment is recommended for patients because it involves minimally invasive techniques. Additionally, post-surgery recovery is quick, and there are fewer complications. Particularly for this disease, medication is often not very effective and does not achieve the therapeutic goal. Surgical treatment can completely resolve the patient's issues, thereby reducing the frequency of recurrence and not affecting the child's growth and development. In the meantime, it is still vital to actively prevent respiratory infections.

Can you swim with patent ductus arteriosus?

If the patient has a history of patent ductus arteriosus, it is recommended that they avoid vigorous exercise, as this can increase the heart's oxygen consumption, leading to symptoms such as palpitations, chest tightness, and difficulty breathing. If it is solely this condition, sometimes palpitations may occur, leading to changes in cardiac function. It is advised not to swim. While appropriate exercise can be beneficial, swimming requires better cardiopulmonary function. It is recommended that patients undergo early surgical treatment to improve their current condition.

Will patent ductus arteriosus show signs of peripheral vascular disease?

Peripheral vascular signs refer to a medical sign characterized by enhanced pulsation of the peripheral arteries and capillaries due to increased pulse pressure. Patients with a patent ductus arteriosus can experience increased pulse pressure, leading to rapid rises and falls in pressure within the peripheral vessels, thereby causing a series of peripheral vascular signs. When a patent ductus arteriosus is combined with peripheral vascular signs, indicating a substantial shunt, it is advisable for such individuals to undergo surgery as soon as possible. Delaying surgery may lead to a right-to-left shunt, resulting in Eisenmenger's syndrome, and the loss of the opportunity for surgical intervention.

Which is more serious, patent ductus arteriosus or ventricular septal defect?

Both of these diseases are types of congenital heart disease, and if there are issues with either of them, the situation can be quite severe. There isn't a distinction between which disease is severe and which is not. If the arterial duct remains open or does not close, surgery is still required for this condition. Patients with ventricular septal defect primarily display changes related to ischemia and hypoxia, and they may also experience recurrent respiratory infections, which are quite serious. Surgery is generally the best treatment. Early surgical intervention can achieve a complete cure, but it is also advisable for the patient to have regular echocardiographic check-ups at the hospital.

Does patent ductus arteriosus require open chest surgery?

Now, many cases of patent ductus arteriosus do not require open-chest surgery, as they can be treated minimally invasively by cardiologists through what is called interventional treatment. The ductus arteriosus is actually a vessel between the aorta and the pulmonary artery during the embryonic stage, which usually closes shortly after birth. If it does not close, it results in a congenital heart disease. In the past, before the widespread use of interventional treatments, open-chest surgery was required to ligate the vessel. With the broad implementation of interventional treatments, cardiologists can now treat this condition minimally invasively. This is mainly done by delivering a spring coil through a catheter to the ductus arteriosus which then blocks the vessel, allowing it to gradually close and thus achieve the therapeutic goal. Alternatively, a gelatin sponge can be delivered to the ductus arteriosus through a catheter to block and eventually close the vessel, achieving the desired treatment outcome.
