Definitions &Translations Pulmonary atresia. Pulmonary atresia is a congenital malformation of the pulmonary valve in which the valve orifice fails to develop. The valve is completely closed thereby obstructing the outflow of blood from the heart to the lungs. The pulmonary valve is located on the right side of the heart between the right ventricle and pulmonary artery.

Dilatation of the Pulmonary Artery, Idiopathic Dilatation of the Pulmonary Artery, Idiopathic. Synonyms of Dilatation of the Pulmonary Artery, Idiopathic. General Discussion. 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. Idiopathic dilatation of the pulmonary artery commonly does not produce symptoms because there is no circulatory abnormality.

Pulmonary Hypertension Pulmonary hypertension is a condition in which blood pressure in the arteries of the lungs (the pulmonary arteries) is abnormally high. 1  Many disorders can cause pulmonary hypertension. 2  People usually have shortness of breath upon exertion and loss of energy, and some people feel light-headed or fatigued on exertion.

Overview Pulmonary hypertension. Overview. Pulmonary hypertension is a type of high blood pressure that affects the arteries in your lungs and the right side of your heart. In one form of pulmonary hypertension, tiny arteries in your lungs, called pulmonary arterioles, and capillaries become narrowed, blocked or destroyed. This makes it harder for blood to flow through your lungs, and raises pressure within your lungs' arteries.

Definitions &Translations Hyperoxia Hyperoxia is excess oxygen or higher than normal partial pressure of oxygen. In medicine, it refers to excess oxygen in the lungs or other body tissues, which can be caused by breathing air or oxygen at pressures greater than normal atmospheric pressure.

Secondary pulmonary hypertension can be a complication of many pulmonary, cardiac and extrathoracic conditions.rimary pulmonary hypertension is a rare disease of unknown etiology, whereas secondary pulmonary hypertension is a complication of many pulmonary, cardiac and extrathoracic conditions.

Pulmonary sequestration From Wikipedia, the free encyclopedia. A pulmonary sequestration (bronchopulmonary sequestration or cystic lung lesion), is a medical condition wherein a piece of tissue that ultimately develops into lung tissue is not attached to the pulmonary arterial blood supply, as is the case in normally developing lung. Contrast-enhanced MRA or even conventional T1-weighted spin-echo (SE) images may help in the diagnosis of pulmonary sequestration by demonstrating a systemic blood supply, particularly from the aorta, to a basal lung mass.

Pulmonary aspiration Pulmonary aspiration is the entry of material from the oropharynx or gastrointestinal tract into the larynx and lower respiratory tract. A person may either inhale the material, or it may be delivered into the tracheobronchial tree during positive pressure ventilation. When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as going down the wrong pipe. Consequences of pulmonary aspiration range from no injury at all, to chemical pn

Top 30 Doctor insights on: What Is The Difference Between Arterial Hypertension And Pulmonary Hypertension Pulmonary Hypertension (Definition) Pulmonary hypertension is elevated blood pressure in the lungs and can be a primary problem or due to other causes. The right side of the heart pumps blood to the lungs and if the BP in the lungs is elevated, the right side of the heart can often fail over time. Pulmonary hypertension can be difficult to diagnose and usually requires echocardiography (cardiac ultrasound) to diagnose.

- Definition of Pulmonary Hypertension in Obstructive Sleep Apnea. Pulmonary hypertension is defined by the presence of resting mean PAP (mPAP) >25 mmHg during right heart catheterization (RHC).14 15 However, previous studies on PH in patients with COPD and OSA have defined PH as mPAP >20 mm Hg.

Pulmonary Hypertension What is Pulmonary Hypertension? Pulmonary arteries are the blood vessels that move blood from the right side of the heart to the lungs where oxygen is received into the blood. The oxygenated blood (blood which carries oxygen) is then transported back to the left side of the heart via the pulmonary veins.
