Anyone may need it. Patent ductus arteriosus (pda) is a normal fetal anatomic connection between the pulmonary artery and aorta that allows blood to bypass the lungs. Because fetuses don't use their lungs to exchange co2 and oxygen (due to a placenta), they do not require much blood flow to the lungs. The PDA normally closes soon after birth as babies start breathing, but can remain open in any infant (esp. Premies).
If needed. This is a natural bypass circuit that redirects most of the blood flow to the body rather than the developing lungs (which are not being used).After birth the rising blood oxygen level leads to closure in most. If it fails to close it can severely hamper a premi's progress, and might be "fixed" very early. In those who retain a PDA but are growing normally, we like to close it by school age.
PDA -Age Dependent? A PDA is required for a baby to survive before birth (allows the blood to bypass the lungs and get to the placenta) 1. Premature baby (medicine: Ibuprofen or others) 2. Premature baby after medicine failures, (surgical ligation, by a pediatric cardiothoracic surgeon) 3. Toddlers into adulthood: in the cath lab if needed; a. Coil embolization b. Amplatzer PDA device or vascular plug.
Device closure. Pdas can almost always be closed in the catheterization laboratory using a small metal coil or device that can be placed with a catheter placed in the vein or artery in the groin rather than a surgery.
PDA Age Dependent? Pda closure (age dependent) babies and adults can have their pdas closed in the cath lab if needed... "hemodynamically significant" cath lab closure, using a coil or device. Many different types and sizes of coils are available, delivered from a small catheter which is inserted in the femoral artery or vein. Another option for large pdas is an aga PDA device or vascular plug. Safe and effective.
It depends. Both patent ductus arteriosus (pda) and atrial septal defect (ASD) can be closed at heart catheterization with closure devices. Another option is surgical closure. The best treatment depends on the size of the defects, the size of the patient, and in asd, the location in the atrial septum. Both surgery and cath closure have good early success and good long-term outcomes.
Should I be concerned if my niece (14 yrs old) has been diagnosed with patent ductus arteriosus. What are treatment options?
Probably okay. Most commonly, when diagnosed in the teen age years, a patent ductus arteriosus (pda) can be treated successfully at cardiac catheterization by placing a "plug" in the PDA which essentially cures the problem. This can be accomplished with low risk and high likelihood of success in a pediatric cardiac center.
Patent Ductus. Yes. It is concerning. Surgical ligation is an option for 14 year old. Prognosis would be good if ligation is done prior to 3 yr old. After that they are more prone to pulmonary hypertension and heart failure. Please consult a congenital heart disease specialist.
Yes/close it. We like to detect these & get them closed by school age. Years ago they opened the chest, now they insert a umbrella like plug from a catheter (often from the groin blood vessel). Ignoring the issue can lead to long term problems with the heart, lungs and potential for a clot to end up in the brain. It is not an urgent issue but one that deserves attention.
Variable issue. Some will close spontaneously. If the kid is having difficulty progressing because of the defect, they can try a medication closure. If unsuccessful & still poor progress it can be surgically closed. If the kid resolves his/her respiratory problem and it continues well after discharge, an elective closure at a later date can be arranged. Each case differs & rx depends on those differences.
Depends. Depends on the size of the ductus and whether it is deemed hemodynamically significant per the cardiologist and neonatologist not all ductuses need treatment in preemies. If treatment is necessary then Indomethacin or IV Ibuprofen are the treatments of choice. If medical therapy with either of the above meds fails then surgical ligation may be indicated.
Ductus Arteriosus. A ductus arteriosus is a vessel that allows babies to survive while in utero... It allows blood to bypass the lungs which are full of amniotic fluid and get to the placenta where gas exchange occurs. A patent ductus arteriosus is simply a vessel that has not closed (patent) once born the lungs relax and the pressures fall. As such, extra blood goes to the lungs, inefficient work for the heart.
Echocardiogram. An ultrasound of the heart, called an echocardiogram, can detect patent ductus arteriosus. This would generally be done by a cardiologist.
PE, CXR, Echo.. A physical exam, chest x-ray and, more importantly, an echocardiogram are the tests needed to diagnose a patent ductus arteriosus.
Several symptoms.. A (p)persistent (d)ductus (a) allows blood to be shunted from the aorta to the pulmonary artery therefore causing more blood to go to the lungs. If the PDA is large, the increased blood flow to the lungs will determine a faster rate and work of breathing, the heart will enlarge and failure to thrive (grow appropriately). A PDA can and should be closed by a cardiologist or surgeon.
PDA. The PDA is an artery that connects the pulmonary artery to the aorta. It is present in everyone and is necessary for survival during fetal life. It allows blood to bypass the fluid filled lungs of the fetus and flow into the aorta and through the umbilical arteries back to the placenta. It normally closes within the first 72-96 hours of life. Occasionally it fails to close, requiring intervention.
