Medicine For Truncus Arteriosus
Congenital heart dx: Truncus arteriosus is a relatively rare form of congenital heart disease consisting of a single, common blood vessel that arises from the heart pumping chambers (ventricles) and gives rise to both the pulmonary arteries (taking blood to the lungs) and the aorta (taking blood to the body). It's caused by a failure of the truncus to separate into a pulmonary artery and aorta during fetal development. ...Read more
Truncus arteriosus is a rare type of heart disease in which a single blood vessel (truncus arteriosus) comes out of the right and left ventricles, instead of the normal 2 vessels (pulmonary artery and aorta). It is present at birth. Abnormal mixing of the blood results in circulation problems requiring corrective surgery to the ...Read more
Usually unknown: Truncus arteriosis is a type of congenital heart disease that results from abnormal development of the heart during fetal development. While it is sometimes associated with certain genetic syndromes, the cause in most cases is unknown. For more information go to www. Mayoclinic. Com -> health information -> diseases & conditions a_z and look up truncus arteriosis (under "t", of coursse). ...Read more
Medication & Surgery: It is usually initially treated with medications for heart failure, but pretty much always requires multiple surgical procedures beginning very early in life. For more information go to www. Mayoclinic. Com -> health information -> diseases & conditions a_z and look up truncus arteriosis (under "t", of coursse). ...Read more
Heart failure.: The more common symptoms associated with truncus are heart failure related. Basically, since the pulmonary arteries are coming off directly from the aorta, the lungs are receiving more blood than they should. This causes the left side of the heart to have to work more to pump the extra blood and at the same time the lungs to be more fluid filled and more stiff. Breathing becomes more labored. ...Read more
Conotruncal disease: During heart development, the pulmonary artery, which provides blood flow to the lungs, and the aorta, which provides blood flow to the body, start as a common tube which is called the common arterial trunk or the truncus arteriosus. If this tube never divides, the name of the resulting congenital heart defect is truncus arteriosus. This is a life-threatening defect requiring surgical repair. ...Read more
Heart failure: It ususlly manifests symptoms of heart insufficiencny ro failure-- cyanosis (blueness), poor feeding, breathing problems, sweating, and irregular heartbeat. For more information go to www. Mayoclinic. Com -> health information -> diseases & conditions a_z and look up truncus arteriosis (under "t", of coursse). ...Read more
Truncus arteriosus: Truncus arteriosus is a rare type of heart disease in which a single blood vessel (truncus arteriosus) comes out of the right and left ventricles, instead of the normal 2 vessels (pulmonary artery and aorta). It is present at birth. Abnormal mixing of the blood results in circulation problems requiring corrective surgery to the normally placed two vessels. ...Read more
Open heart surgery: Repair of truncus arteriosus is a complicated procedure, because the aorta and pulmonary artery did not separate during development. A patch is placed to close the communication between the right and left ventricle. The pulmonary arteries are taken off of the aorta and a new tube graft is placed into the right ventricle and connected to the pulmonary arteries to restore a normal circulation. ...Read more
Yes: Formation of primitive aortic arches begins in the third week of fetal life. The aortic and pulmonary outflow tracts are fully separated by 8-9 weeks. ...Read more

My daughter (almost 8) had surgery to correct truncus arteriosus at 5 days old. She has lately been complaining of pain in her scar. What should we do?
Do a lot of people have a baby with pulmonary sling, complete tracheal rings, and truncus arteriosus?
No: These entities are relatively rare. However, today's pediatric cardiac and thoracic surgeons are experts in repairing even the most complicated lesions. You should discuss your concerns with them. Good luck. ...Read more
Is it possible for a child to have a patent foramen ovale (pfo) and a patent ductis arteriosus (pda)?
Yes: It is a normal feature of the heart prior to birth and may persist in some. The PDA is usually picked up on exam, the pfo would only be accessible to advanced studies. ...Read more
Can you give me more info on experience with a child who has a patent foramen ovale (pfo) and a patent ductis arteriosus (pda)?
Common: All normal fetuses have a pfo and a pda. These are connections between the "left heart" and the "right heart" that allow blood to bypass the lungs and flow properly to the placenta. Typically, in the first 24 hours after birth, the PDA closes. Pfo closure can be more gradual and can be present for many months, and still be a normal finding. Persistent patency can be a problem. ...Read more
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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

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
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
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
Will not "heal":
An adult with a PDA will not have spontaneous closure. Spontaneous closure of a small PDA is a common occurrence for in infants, but is rare after the first year of life.
In most cases, even in adults, if treatment of a PDA is required, a PDA can be effectively and safely closed with a device placed by catheterization. This is typically an outpatient procedure with excellent results. ...Read more
