30-year-old female patient with Patent Ductus Arteriosus (PDA)?

Hello Dr.
Lee, I would like to ask about my girlfriend who is 30 years old.
She recently underwent a cardiology examination and was found to have a patent ductus arteriosus (PDA) and some mild cardiac hypertrophy.
Since she is currently not experiencing any significant symptoms, is it necessary for her to undergo catheterization surgery? If she becomes pregnant, are there any associated risks? Is there a possibility of genetic inheritance? If catheterization surgery is required, could you recommend a physician who can assist with further evaluation or the procedure? Thank you for your response.

Justin, 30~39 year old female. Ask Date: 2011/08/23

Hello Justin, regarding your question: your girlfriend is 30 years old and has a patent ductus arteriosus (PDA) with some mild cardiac hypertrophy.
Since she currently has no significant symptoms, is there a definite need for catheterization surgery? If she becomes pregnant, are there any risks? Is there a possibility of genetic inheritance?
Firstly, a patent ductus arteriosus (PDA) is a congenital heart defect that represents an important vascular connection in fetal circulation, linking the aorta and the pulmonary artery.
This connection should close after birth but remains open, leading to a shunting of blood.
The exact cause of this condition is unknown, but it is more common in premature infants.

The pathophysiology of PDA primarily involves blood shunting from the high-pressure aorta to the low-pressure pulmonary artery, which imposes a long-term volume overload on the heart, potentially leading to heart failure and pulmonary hypertension.
Additionally, the turbulent flow created by this connection can damage the endothelium of blood vessels, increasing the risk of infective endocarditis.

Even if the shunt is small and has not yet caused significant effects on the heart, closure of the PDA may be considered to prevent infective endocarditis.
Currently, there are two methods to close a patent ductus arteriosus: surgical intervention or catheter-based intervention.
The latter involves using a catheter to occlude the ductus with coils or a closure device.
Most cardiovascular centers at medical institutions in Taiwan are equipped with the necessary expertise and services for this procedure, and it is advisable to seek consultation.
Take care.

More Info

Patent Ductus Arteriosus (PDA) is a heart condition that occurs when the ductus arteriosus, a blood vessel that allows blood to bypass the lungs in a fetus, fails to close after birth. This condition can lead to increased blood flow to the lungs and heart, potentially causing complications such as heart enlargement and heart failure if left untreated.
In a 30-year-old woman, the presence of PDA and mild cardiac hypertrophy (enlargement of the heart) can be concerning, but the need for intervention often depends on the severity of the condition and the presence of symptoms. Since your girlfriend has not experienced any unusual symptoms, it may not be immediately necessary to undergo catheter-based intervention or surgery. However, regular monitoring by a cardiologist is essential to assess any changes in her condition over time.

When considering pregnancy, it is crucial to evaluate the risks associated with PDA. Women with untreated PDA may face increased risks during pregnancy, including heart failure, pulmonary hypertension, and complications during labor. The additional blood volume and cardiac output required during pregnancy can put extra strain on the heart. Therefore, it is advisable for her to consult with a cardiologist who specializes in congenital heart disease before attempting to conceive. This specialist can provide a thorough evaluation and discuss the potential risks and management strategies during pregnancy.

Regarding the hereditary aspect, PDA can be associated with certain genetic syndromes, but in many cases, it occurs sporadically without a family history. If there are concerns about genetic predisposition, genetic counseling may be beneficial.

If intervention is deemed necessary, catheter-based closure of the PDA is a common and effective procedure. The decision for surgery or catheterization should be made collaboratively with a cardiologist who can assess her specific case and recommend the best course of action. It is essential to find a cardiologist with experience in treating PDA, particularly in adults, as this condition is often more commonly addressed in pediatric patients.

In summary, while your girlfriend's PDA and mild heart enlargement warrant careful monitoring, immediate intervention may not be necessary if she remains asymptomatic. However, consulting with a cardiologist is crucial, especially if she is considering pregnancy. They can provide tailored advice regarding the risks, potential treatments, and the best approach to ensure both her health and the health of a future pregnancy. Regular follow-ups and a comprehensive evaluation will help manage her condition effectively.
