Ductus arteriosus refers to an open passageway-or temporary blood vessel (ductus)-that carries blood from the heart via the pulmonary artery to the aorta before birth.
The right ventricle pumps blood into the pulmonary artery and blood reaches the aorta through a patent ductus arteriosus (see description in the previous section).
The most common obstruction defects are pulmonary valve stenosis, aortic valve stenosis, and coarctation of the aorta.
In pulmonary stenosis, the pulmonary valve does not open properly, forcing the right ventricle to work harder.
Eisenmenger's complex is a ventricular septal defect coupled with pulmonary high blood pressure, an enlarged right ventricle, and sometimes an aorta that is not positioned correctly.
Cyanotic defects include truncus arteriosus, total anomalous pulmonary venous return, tetralogy of Fallot, transposition of the great arteries, tricuspid atresia, and pulmonary atresia.
Truncus arteriosus is a complex malformation in which only one artery comes from the heart and forms the aorta and pulmonary artery.
Total anomalous pulmonary venous return is a condition in which the pulmonary veins that bring oxygen-rich blood from the lungs back to the heart are not connected to the left atrium.
Instead, the pulmonary veins drain through abnormal connections to the right atrium.
The major defects are a large hole (ventricular septal defect) between the ventricles, which allows oxygen-poor blood to mix with oxygen-rich blood, and narrowing at or beneath the pulmonary valve.
In transposition (reversal of position) of the great arteries, the positions of the pulmonary artery and the aorta are reversed, causing oxygen-rich blood to re-circulate to the lungs while oxygen-poor blood goes to the rest of the body.
In pulmonary atresia, the baby lacks a pulmonary valve and blood cannot flow properly from the right ventricle into the pulmonary artery and on to the lungs.
Arterial switch, to correct transposition of the great arteries, involves connecting the aorta to the left ventricle and connecting the pulmonary artery to the right ventricle.
Balloon valvuloplasty uses a balloon-tipped catheter to open a narrowed heart valve, improving the flow of blood in pulmonary stenosis.
Transposition of the great arteries also can be corrected by the Damus-Kaye-Stansel procedure, in which the pulmonary artery is cut in two and connected to the ascending aorta and the farthest section of the right ventricle.
For tricuspid atresia and pulmonary atresia, the Fontan procedure connects the right atrium to the pulmonary artery directly or with a conduit, and the atrial defect is closed.
Pulmonary artery banding, narrowing the pulmonary artery with a band to reduce blood flow and pressure in the lungs, is used for ventricular septal defect, atrioventricular canal defect, and tricuspid atresia.
To correct aortic stenosis, the Ross procedure grafts the pulmonary artery to the aorta.
For tetralogy of Fallot, tricuspid atresia, or pulmonary atresia, the shunt procedure creates a passage between blood vessels, sending blood into parts of the body that need it.
For transposition of the great arteries, venous switch creates a tunnel inside the atria to re-direct oxygen-rich blood to the right ventricle and aorta, and venous blood to the left ventricle and pulmonary artery.
Ductus-The blood vessel that joins the pulmonary artery and the aorta.
Following the Heimlich maneuver, dysphagia (swallowing difficulty) and obstructive pulmonary edema (fluid accumulation in the lungs) may occur.

Blood clots in the renal arteries are uncommon, but when they do occur, there is a risk of pulmonary embolism, a dangerous condition that occurs when the clot or a portion of the clot dislodges and travels to the lungs.

Pulmonary edema can result from fluids leaking into the alveoli (air sacs) of the lung.
Pulmonary function tests are a group of procedures that measure how well the lungs are functioning.
Pulmonary function tests help a doctor to diagnose respiratory diseases and disorders such as asthma, chronic obstructive pulmonary disease (COPD), and emphysema, and mechanical injury by measuring the degree of lung impairment.
There are many types of pulmonary function tests.
With the exception of arterial blood gas, pulse oximetry, and total lung capacity, pulmonary function tests are performed using spirometry (from the Greco-Latin term meaning "to measure breathing").
Taken together, pulmonary function tests give a good picture of how much air is moving in and out of the lungs and how efficiently oxygen is moved into the blood and carbon dioxide is moved out.
Except for the arterial blood gas tests and pulse oximetry, pulmonary function tests should not be given to patients who have had a recent heart attack, or who have certain other types of heart disease.

Transposition of the great arteries (TGA) is a birth defect causing a fatal condition in which there is a reversal, or switch, in the primary connections of the two main (great) blood vessels to the heart, the aorta and pulmonary artery.
There are two great arteries that transport blood away from the heart, the pulmonary artery and the aorta.
Normally, the pulmonary artery carries blood from the right ventricle to the lungs.
At the same time, blood in the lungs goes to the left atrium, the left ventricle, but then back to the lungs rather than going to the body because the pulmonary artery is connected to the left ventricle.
Pulmonary artery-An artery that carries blood from the heart to the lungs.
The ventricle on the left side pumps blood full of oxygen through the body; the ventricle on the right side pumps the same blood through the pulmonary artery to the lungs to take up oxygen.
The problem starts very early in the uterus with a narrowed pulmonary valve and a hole between the ventricles.
During surgery, the pulmonary valve is widened, the ventricular septal defect is closed, and any interim correction is removed.
Patent ductus arteriosus (PDA) is a heart defect that occurs in infants when the ductus arteriosus (the temporary fetal blood vessel that connects the aorta and the pulmonary artery) does not close at birth.
The ductus arteriosus is a temporary fetal blood vessel that connects the aorta and the pulmonary artery before birth.
The pressure between the heart and lungs of an individual affected by PDA causes some of the oxygenated blood that should go out to the body (through the aorta) to return back through the PDA into the pulmonary artery.
The pulmonary artery takes the blood immediately back to the lungs.
As the heart responds to the increased demands for more oxygenated blood by pumping harder, the pulmonary artery has to change in size and shape in order to adapt to the increased amount and force of the blood.
In some cases, the increase in size and shape changes the pressure in the pulmonary artery and lungs.
If the pressure in the lungs is higher than that of the heart and body, blood returning to the heart will take the short cut back into the aorta from the pulmonary artery through the PDA instead of going to the lungs.
It is usually associated with cancer, chronic obstructive pulmonary disease (COPD), or another chronic disease that progresses very slowly.
