Pulmonary-artery Sentence Examples

Normally, the pulmonary artery carries blood from the right ventricle 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.

Six or seven species of mosquitoes are also the intermediate hosts of Filaria immitis, which infests the right auricle and pulmonary artery of the dog, and occurs throughout the tropics, in southern Europe, the United States of America, and elsewhere.

None were visible on main pulmonary artery angiography due to reversal of flow in the affected pulmonary artery branches.

The following figure shows the pressure in the main pulmonary artery in the dog during a period of hypoxia.

Pulmonary valve A valve at the junction of the right ventricle to the pulmonary artery.

The only thing doctors had to do was balloon the stent in his pulmonary artery.

Patent ductus arteriosus-A congenital defect in which the temporary blood vessel connecting the left pulmonary artery to the aorta in the fetus doesn't close after birth.

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).

Truncus arteriosus is a complex malformation in which only one artery comes from the heart and forms the aorta and pulmonary artery.

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.

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 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.

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.

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.

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.
