Heart problem that is seen most commonly in premature babies.
A condition in which the ductus arteriosus fails to close shortly after birth. This results in a significant right to left shunt of blood. Babies with this condition often develop heart and lung failure. Treatment with drugs (indomethacin) is possible, and surgical ligation is often necessary.
a blood vessel present in the fetus that allows blood coming from the placenta that is rich in oxygen to bypass the left side of the heart and lungs and flow through this blood vessel to the rest of the body. It usually closes in the first two weeks of life in term infants but may remain open in the preterm infant, requiring treatment to close it.
Blood vessel in the heart remaining open after it should have closed.
A ductus that fails to undergo normal closure in the early post-natal period. syn. persistently patent ductus arteriosus, persistent arterial duct.
Abnormal persistence after birth of an embryonic blood vessel connecting the pulmonary artery to the aorta; only rarely seen in horses.
PDA is the most common heart problem in premature babies. Before birth, much of a fetus's blood goes through a passageway (ductus arteriosus) from one blood vessel to another, bypassing the lungs, because the lungs are not yet in use. This passageway should close soon after birth, so the blood can take the normal route from heart to lungs and back. If it doesn't close, blood doesn't flow correctly. In some cases, drug treatment can help close the passageway. If that doesn't work, surgery can also close it.
A term used to describe an open arterial duct connecting the pulmonary artery to the aorta.
Serious, sometimes fatal, heart defect; a fetal shunt which allows blood to bypass the lungs fails to resolve prior to birth, resulting in a heart murmur and poorly oxygenated blood.
condition in which the connecting blood vessel between the pulmonary artery and the aorta in fetal circulation stays open in the newborn.
a ductus arteriosus that failed to close at birth; may require surgical correction
(PDA): A "typical" situation in preemies where the fetal blood vessel which links the aorta and the pulmonary artery does not clothes following birth.
Failure of the Patent Ductus to close shortly after birth as it should.
In a fetus and new-born baby, a normal opening is present between the pulmonary artery and the aorta. It should naturally close soon after birth. Patent ductus arteriosus occurs when this opening does not close.
A blood vessel between the pulmonary artery and the aorta. This is normal in fetal life, but can cause problems after birth, particularly in premature infants. This condition causes abnormal cardiac circulation and pressure in the heart during contractions. The vast majority close spontaneously and cause no problems. Medical or surgical correction may be done. This is only an abnormality if it causes significant medical problems.
Condition in which ductus arteriosus (hole between aorta and pulmonary artery) remains open (patent); usually closes within hours after birth; prevents transport of blood and nutrients to the body.
A blood vessel present in all infants that usually closes shortly after birth. It connects the aorta to the pulmonary artery. When it remains open, it allows extra blood to pass through from the aorta to the lungs.
Abnormally persistent opening of the arterial duct connecting the pulmonary artery and the aorta. The ductus arteriosis usually closes within 24 hours of birth thus preventing blood from bypassing the lungs.
Abnormal persistence of the opening in the arterial duct that connects the pulmonary artery to the descending aorta; this opening normally closes within 24 hours of birth. (Read about patent ductus arteriosus in " Congenital Heart Defects")
A condition in which the blood vessel that connects the aorta (the main artery of the body) and the pulmonary artery (the artery that brings blood to the lungs) does not close as it should after birth.
(PDA) — open ductus arteriosus after birth.
A congenital defect in which the opening between the aorta and the pulmonary artery does not close after birth.
the failure of a fetal shunt which allows blood to by-pass the lungs to go away; can cause serious cardiac dysfunction and death.
This describes a condition where the fetal blood vessel linking the aorta and the pulmonary artery does not close properly. This is not an uncommon condition in premature infants.
Persistence of communication between main pulmonary artery & aorta; a congenital heart defect that results in failure of the ductus arteriosus (the channel of communication between main pulmonary artery & aorta in a fetus), from closing
Patent ductus arteriosus (PDA) is a congenital heart defect wherein a child's ductus arteriosus fails to close after birth. Symptoms include shortness of breath and cardiac arrhythmia, and may progress to congestive heart failure if left uncorrected.
