Patients with patent ductus arteriosus should avoid running. The condition can cause a left-to-right shunt, increasing pulmonary circulation and the volume of blood returning to the left heart system, which in turn leads to increased left heart workload and potential left heart dysfunction. In adults with patent ductus arteriosus, the clinical symptoms vary depending on the size of the shunt. Those with very small shunts may exhibit no subjective symptoms clinically. Patients with moderate shunts often experience symptoms such as fatigue, palpitations after activity, shortness of breath, and chest tightness. Those with large shunts, often accompanied by severe secondary pulmonary hypertension, may experience a right-to-left shunt, leading to cyanosis and very severe clinical symptoms.

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.

Can a patent ductus arteriosus be treated with minimally invasive surgery?

Patent ductus arteriosus refers to the condition in infants where the ductal connection between the pulmonary artery and the aortic arch from the embryonic period remains open after the first year of birth. Generally, this duct is tubular or funnel-shaped and most cases can be treated minimally invasively. Surgical treatment is considered only if there are severe adhesions involving the aorta or pulmonary artery, or there are developmental issues. Therefore, patent ductus arteriosus can be treated with minimally invasive surgery, and most cases are amenable to such treatment.

Is a 4mm patent ductus arteriosus considered large?

Patent ductus arteriosus is a type of congenital heart disease. Generally, patients around the age of six months to one year may not necessarily have their ductus arteriosus close. If it does not close by around one year of age, it is considered a congenital heart disease, and it is recommended to seek early surgical treatment at a hospital. Surgery is needed if the condition exceeds approximately 4mm in size. If the patient currently shows no symptoms, it is possible to initially observe the condition. However, if symptoms persist, accompanied by palpitations, chest tightness, difficulty breathing, especially if respiratory infections recur, treatment is necessary.

How to treat patent ductus arteriosus?

The arterial duct connects the main pulmonary artery to the descending aorta, serving as the primary channel for blood circulation during the fetal period. After birth, it generally becomes obstructed within a few months due to disuse; if it remains open after one year, it is referred to as patent ductus arteriosus (PDA). The length and diameter of an unclosed arterial duct vary, affecting hemodynamics differently, and consequently, prognoses differ. An unclosed arterial duct can easily induce infectious endocarditis; thus, even if the shunt is small, it is advisable to seek early interventional or surgical treatment. The surgery has a high safety success rate and can be performed at any age. However, surgery is contraindicated for patients who have developed secondary pulmonary artery obstruction and exhibit right-to-left shunting.
