Patent Ductus Arteriosus or [PDA] is a Heart defect named after a passageway that allows blood to flow from the right atria to the aorta.
It is considered a congenital Heart defect.
This passageway typically stays open while in utero and immediately following birth the passageway closes.
If it doesn’t close properly – it is considered Patent Ductus Arteriosus.
Prostaglandins, are a group of physiologically active lipid molecules or compounds, play a role in keeping the passageway open.
Prostaglandins normally have a diverse “hormone-like” effect on the body.
There are many different types and functions.
- Usually no symptoms
- Left ventricular failure
- Pulmonary hypertension
- Cardiac murmur “Machinery“
- Shortness of breath
- Other respiratory problems
**** Congestive Heart Failure can be a complication
ECG is usually normal
X-ray can be useful
Echocardiography/Doppler is essential to confirm the diagnosis
MRI and CT can often visualize the defect itself.
- Indomethacin causing the closure of the passageway
- Surgical repair
- Antibiotic treatment to limit possible Endocarditis
