	Lung Transplantation - Definition, Purpose, Demographics, Description, Diagnosis/preparation, Aftercare, Risks, Normal ...
		Inferior and superior pulmonary veins and pulmonary artery are separated, and lung is removed (B).
		Arterial blood gases (ABG) test, which measures the amount of oxygen that the blood is able to carry to body tissues.
		Pulmonary function tests (PFTs), which measure lung volume and the rate of air flow through the lungs; the results measure the progress of the lung disease.

	Pulmonary Artery Stenosis
		Pulmonary artery stenosis is a narrowing (stenosis) that occurs in the pulmonary artery, a large artery that sends oxygen-poor blood into the lungs to be enriched with oxygen.
		Pulmonary artery stenosis is a congenital heart defect, meaning it is a defect that is inborn or exists at birth.
		If your child is diagnosed with pulmonary artery stenosis, your pediatrician or primary care doctor will recommend that you meet with a congenital heart specialist (a doctor who has the training and equipment to determine your child’s heart problem and order the necessary special tests, medical care, heart surgery, and follow-up checkups).

	ISACCD - Glossary A-A
		This is in contrast to the general rule that the first arch artery gives rise to the carotid artery contralateral to the side of the aortic arch (i.e.: right carotid artery in left aortic arch and left carotid artery in right aortic arch).
		An autosomal dominant multi-system syndrome consisting of intrahepatic cholestasis, characteristic facies, butterfly-like vertebral anomalies and varying degrees of peripheral pulmonary artery stenoses or diffuse hypoplasia of the pulmonary artery and its branches.
		In patients with l-transposition of the great arteries and in patients who have had a previous Mustard or Senning procedure, it is used as part of a"double switch procedure" which results in anatomic correction of the circulation, with the left ventricle supporting the systemic circulation.

	Welcome to Thic - Pulmonary Stenosis
		The pulmonary artery is the major blood vessel which carries "blue blood", low in oxygen, from the right side of the heart\ to the lungs.
		The pulmonary valve is located at the beginning of the pulmonary artery.
		Pulmonary stenosis can occur in several ways: the valve may have only two leaflets which are partially stuck together or three leaflets which may be thick and partly or completely stuck together.

	Pulmonary Artery Catheter
		Specifically, a thermistor in the distal end of the pulmonary artery catheter sensed the change in blood temperature produced by the rapid injection of iced (or room temperature) solution administered through the proximal (central venous pressure) port of the catheter.
		Because the pulmonary artery diastolic pressure agrees well with the pulmonary artery occlusion pressure in the absence of pulmonary hypertension, it is logical to use the end--diastolic pressure as an indirect measurement of left atrial pressure.
		Indications for use of the pulmonary artery catheter are numerous and often controversial.

	Pulmonary Hypertension - My Child Has - Children's Hospital Boston
		Pulmonary hypertension is a rare blood vessel disorder that results in high blood pressure in the lungs.
		This type of pulmonary hypertension is caused by an inadequate amount of oxygen in the bloodstream as a result of either lung disease, exposure to high altitude or breathing disorders such as chronic lung disease, sleep apnea, emphysema and bronchitis.
		This type of pulmonary hypertension is caused by blood clots in the pulmonary arteries, pulmonary embolism or sickle cell disease.

	Pulmonary Hypertension Association
		Pulmonary thromboendarterectomy is the definitive treatment for chronic pulmonary hypertension as the result of thromboembolic disease.
		The heart is emptied on bypass, and a temporary pulmonary artery vent is placed in the midline of the main pul-monary artery 1 cm distal to the pulmonary valve.
		An incision is then made in the right pulmonary artery from beneath the ascending aorta out under the superior vena cava and entering the lower lobe branch of the pulmonary artery just after the take-off of the middle lobe artery.

	Blood Pressure
		The pulmonary artery is the blood vessel carrying oxygen-poor blood from the right ventricle, one of the pumping chambers of the heart, to the lungs.
		In the PH patient, the mean blood pressure in the pulmonary artery is greater than 25 mm Hg at rest and 30 mm Hg during exercise.
		This abnormally high pressure (pulmonary hypertension) is associated with changes in the small blood vessels in the lungs, resulting in an increased resistance to blood flowing through the vessels.

	CIGNA - Dilatation of the Pulmonary Artery, Idiopathic
		Idiopathic dilatation of the pulmonary artery (IDPA) is a rare congenital defect characterized by a wider than normal main pulmonary artery in the absence of any apparent anatomical or physiological cause.
		Clinical signs are minimal, and usually consist of a palpable pulmonary ejection sound that disappears when the patient inhales, a soft pulmonary ejection systolic murmur (abnormal heart sound), and splitting of the second sound on breathing in.
		The cause of idiopathic dilatation of the pulmonary artery is unknown.

	ICU-USA - Tour - PA Catheter
		Pulmonary artery catheterization is a procedure performed to provide information regarding the patient's blood circulation, specifically, the pressure and amount of fluid or blood in the circulation and an assessment of the pumping action of the heart.
		As the pulmonary artery catheter is inserted, it passes through the right-side heart chambers (atrium and ventricle) into the lung blood vessels where it rests.
		Use of pulmonary artery catheterization is associated with potential complications that are infrequent but include serious heart rhythm disturbance, blood clot formation around the catheter, lung collapse, and catheter related infections.

		As pulmonary artery pressure increased, pulmonary regurgitant flow velocity became higher; the pulmonary artery-to- right ventricular pressure gradient in diastole (PG) was estimated from the pulmonary regurgitant flow velocity (V) by means of the simplified Bernoulli equation (PG = 4V2).

	Primary Pulmonary Hypertension, PPH
		Primary pulmonary hypertension or PPH occurs when blood pressure in the pulmonary artery or the major blood vessel connecting the right heart ventricle and the lungs is higher than normal (The lungs are responsible for supplying the blood with oxygen and ridding the blood of carbon dioxide).
		Primary pulmonary hypertension arises for no apparent reason and is therefore synonymously known as idiopathic pulmonary hypertension or unexplained pulmonary hypertension.
		The normal pressure in the pulmonary artery is between 14 and 18 mm Hg.
