What is the seriousness of ductus arteriosus/venosus and foramen ovale?

What is the seriousness of ductus arteriosus/venosus and foramen ovale?

Needs to be closed: Ductus arteriosus(PDA) is normal at birth and should close soon after. If persistant ,PDA is abnormal and may become a significant problem after few months of life. It should be evaluated by cardiologist and may be closed through a catheter and not require surgery. Foramen Ovale (Communication between R/ L upper chambers of heart) normal at birth and stays open in ~25% of people.Rarely a problem . ...Read more

What is patent ductus arteriosus?

What is patent ductus arteriosus?

Fetal structure: A patent ductus arteriosus (pda) is a small vessel that connects the pulmonary artery to the aorta during fetal life. Once the umbilical cord is cut and we are exposed to an oxygen rich environment that vessel should "shrivel up" and become an unobtrusive ligament. In some people it never closes and in some it will need to be addressed. ...Read more

What is a patent ductus arteriosus?

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. ...Read more

What exactly is patent ductus arteriosus?

What exactly is patent ductus arteriosus?

PDA: Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus ...Read more

What?Causes ?The patent ductus arteriosus?

Causes the PDA: The PDA is a critical vessel that allows the blood to bypass the lungs and get to the placenta while babys are still inside, in mom's uterus. The lungs are full of amniotic fluid and don't do any gas exchange (o2 delivery and co2 release) eveyone is born with a pda, it persists... Open (patent) most commonly in premature babies. There is no absolute answer as to why it stays open in some people. ...Read more

How do you treat patent ductus arteriosus?

Depends: In premature infants it is usually closed with medication (indomethacin). In the uncommon premature infant in which it does not work surgical ligation is required. Most pdas that are diagnosed in otherwise healthy children are closed with a catheter based device when they are over 2 years old. ...Read more

How do?You ?Treat patent ductus arteriosus?

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. In premature infants, it can often be closed with a medication. If this fails, surgery is most often done since they are too small for catheter-based methods. Soon there may be smaller systems. ...Read more

What are the symptoms of patent ductus arteriosus?

What are the symptoms of 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. ...Read more

When do you worry about a patent ductus arteriosus?

Fixed by school age: Pda's may require medicine closure or surgery in a frail premi . The energy drain from the excessive heart work may prevent progress in the nicu. In stable infants they are often watched. If they are missed or picked up in middle childhood, elective closure is often advised & can often be done through a catheter. ...Read more

I want to know what's the patent ductus arteriosus?

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. ...Read more

Why did patent ductus arteriosus commonly left open?

Confusing question: A PDA is an energy saving bypass used in the developing fetus to send most of the hearts blood flow to the body rather than the lungs before birth. After birth, the rise in blood oxygen content usually triggers the bypass to close.It remains open in some cases & can create problems in later life. Closure by medicine, catheter or surgery is the common practice in the us by school age. ...Read more

How expensive is the patent ductus arteriosus repair?

How expensive is the patent ductus arteriosus repair?

Widely variable: The cost of PDA repair is widely variable both by location of where in the US it is done and the procedure performed (surgery vs. catheter). Most are now done by catheter with no incision and less than a one day stay. This is a great (and fair) question to ask your doctor's office/hospital where this will be done. In these days of managed care, I believe its best to know what you are getting into. ...Read more

What's the safest way to treat patent ductus arteriosus?

It depends: In newborns, closure of a patent ductus arteriosus may be achieved through medications (such as Indomethacin or ibuprofen) or by surgical ligation and division. In older children or adults, ductal closure is usually performed by a catheter-based approach, or surgical ligation and division. All of these therapies are generally safe, but all have certain risks associated with them. ...Read more

Can you tell me how do I treat patent ductus arteriosus?

Depends: Treatment depends on the age of the patient and size of the patent ductus arteriosus (pda). Tiny pdas may require no treatment. Large pdas in prematures may close with Indomethacin administration or require surgery. Significant pdas in older children and adults can be closed by catheter delivered devices in most cases. Long-term outcomes are excellent. ...Read more

Can you tell me about kids with PDA (patent ductus arteriosus).?

Long-term normal: A patent ductus arteriosus (pda) is a normal structure before birth, that allows blood pumped from the right ventricle to bypass the lungs to reach the aorta and ultimately the placenta. If the PDA stays open after birth, it can result in excess blood flow to the lungs. If necessary, the PDA can be closed by surgery or catheterization with very high levels of success and long-term good health. ...Read more

What sort of symptoms are in a child with patent ductus arteriosus?

What sort of symptoms are in a child with patent ductus arteriosus?

It varies: Children with patent ductus arteriosus (pda) may be entirely asymptomatic (often diagnosed by a typical heart murmur) or they may have signs and symptoms of congesitve heart failure secondary to a left-to-right shunt. These symptoms may include a fast heart rate, fast, abnormal breathing, and failure to gain weight appropriately. The symptoms depend on the size of the PDA and degree of shunting. ...Read more

What is the definition or description of: Patent ductus arteriosus?

Fetal circulation: A PDA (patent ductus arteriosus) is simply persistent fetal circulation. Before an infant is born and is not using their lungs, this artery is a pathway that allows oxygenated blood to get to the body's tissues. After birth the artery will normally close on its own but if not it is either monitored or treated medically or with surgery. ...Read more

What activities should I avoid since I have patent ductus arteriosus?

Nothing much: I assume it is too small to bother closing. You should avoid poor dental hygiene, and IV drug abuse (to avoid endocarditis). Otherwise feel free to do whatever. ...Read more
