Q. What Is Patent Ductus Arteriosus ?

Patent ductus arteriosus (PDA) is a heart problem that occurs soon after birth in some babies. In PDA, there is an abnormal circulation of blood between two of the major arteries near the heart. Before birth, the two major arteries-the aorta and the pulmonary artery-are normally connected by a blood vessel called the ductus arteriosus, which is an essential part of the fetal circulation...

After birth, the vessel is supposed to close within a few days as part of the normal changes occurring in the baby's circulation. In some babies, however, the ductus arteriosus remains open (patent). This opening allows blood to flow directly from the aorta into the pulmonary artery, which can put a strain on the heart and increase the blood pressure in the lung arteries...

Q. How the Heart Works

Your child's heart is a muscle about the size of his or her fist. It works like a pump and beats 100,000 times a day. The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. Then, oxygen-rich blood returns from the lungs to the left side of the heart, and the left side pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels...

Heart Valves

Four valves control the flow of blood from the atria to the ventricles and from the ventricles into the two large arteries connected to the heart.

* The tricuspid (tri-CUSS-pid) valve is in the right side of the heart, between the right atrium and the right ventricle.

* The pulmonary (PULL-mun-ary) valve is in the right side of the heart, between the right ventricle and the entrance to the pulmonary artery, which carries blood to the lungs.

* The mitral (MI-trul) valve is in the left side of the heart, between the left atrium and the left ventricle.

* The aortic (ay-OR-tik) valve is in the left side of the heart, between the left ventricle and the entrance to the aorta, the artery that carries blood to the body...

Q. What Causes Patent Ductus Arteriosus ?

The cause of patent ductus arteriosus (PDA) is not known. Genetics may play a role. A defect in one or more genes could prevent the ductus arteriosus from closing normally after birth.

PDA is more common in : -

* Premature infants (babies born too early)

* Infants with genetic abnormalities such as Down syndrome

* Infants whose mother had German measles (rubella) during pregnancy...

Q. What Are the Signs and Symptoms of Patent Ductus Arteriosus ?

A heart murmur may be the only sign that a baby has patent ductus arteriosus (PDA). A heart murmur is an extra or unusual sound heard during the heartbeat.Some infants may develop signs or symptoms of volume overload on the heart and excess blood flow in the lungs.

Signs and symptoms may include : -

* Fast breathing, working hard to breathe, or shortness of breath, or in the case of a premature infant, need for increased oxygen or ventilatory support

* Poor feeding and poor weight gain

* Tiring easily

* Sweating with exertion (such as while feeding)...

Q. How Is Patent Ductus Arteriosus Treated ?

The goal of treatment is to close the patent ductus arteriosus (PDA) to prevent complications and reverse the effects of increased blood volume. Small PDAs often close without treatment...
