| valve of pulmonary trunk | <anatomy, cardiology> The heart valve that divides the right ventricle and the pulmonary artery. The pulmonic valve opens when the right ventricle contracts allowing blood to flow into the pulmonary artery. The pulmonic valve on closure prohibits the backwash of unoxygenated blood into the right ventricle. The pulmonic valve has 3 valve cusps. (27 Sep 1997) |

| vein, pulmonary | One of four vessels that carry aerated blood from the lungs to the right atrium of the heart. (the four are the right and left superior and inferior pulmonary veins). The pulmonary veins are the only veins that carry bright red oxygenated blood. (12 Dec 1998) |
| medial basal branch of pulmonary artery | <anatomy, artery> A branch of the basal part of inferior lobar branches of the left and right pulmonary arteries. Synonym: ramus basalis medialis. (05 Mar 2000) |
| resistance, pulmonary | The opposition of the respiratory tree to air flow. (12 Dec 1998) |
| reverse pulmonary oedema pattern | <radiology> Loeffler pneumonia, chronic eosinophilic pneumonia (12 Dec 1998) |
| granuloma, plasma cell, pulmonary | A pseudotumour of the lung composed of inflammatory cells and showing complete maturity of fibroblastic components with a striking lack of mitosis. It is also called postinflammatory pseudotumour and pseudoneoplastic pneumonitis. (berardi, r.s. Et al. Inflammatory pseudotumours of the lung. Surg gynecol obstet 156:89-96, jan 83) (12 Dec 1998) |
| right inferior pulmonary vein | <anatomy, vein> The vein returning oxygenated blood from the inferior lobe of the right lung to the left atrium. Synonym: vena pulmonalis inferior dextra. (05 Mar 2000) |
| right interlobar pulmonary artery | <radiology> Upper limit of normal: 15 mm (12 Dec 1998) |
| right pulmonary artery | <anatomy, artery> The longer of the two terminal branches of the pulmonary trunk, it passes transversely across the mediastinum passing inferior to the aortic arch to enter the hilum of the right lung. Branches are distributed with the bronchi; frequent variations occurs. Typical branches to the superior lobe (rami lobi superioris ) are apical (ramus apicalis ), anterior ascending (rami anterior ascendens ), anterior descending (ramus anterior descendens ), posterior ascending (ramus posterior ascendens ), and posterior descending (ramus posterior descendens ); to the middle lobe (rami lobi medii ) are medial (ramus medialis ) and lateral (ramus lateralis ); and to the inferior lobe (rami lobi inferioris ) are superior (apical) branch of inferior lobe (ramus superior (apicalis) lobi inferioris ), and the anterior, lateral (lateralis), medial (medialis) and posterior basal branches (rami basalis). Synonym: arteria pulmonalis dextra. (05 Mar 2000) |
| right superior pulmonary vein | <anatomy, vein> The vein returning oxygenated blood from the superior and middle lobes of the right lung to the left atrium. Synonym: vena pulmonalis superior dextra. (05 Mar 2000) |
| chronic obstructive pulmonary disease | <disease> A progressive disease process that most commonly results from smoking. Chronic obstructive pulmonary disease is characterised by difficulty breathing, wheezing and a chronic cough. Treatment includes absolute avoidance from smoking, bronchodilators and oxygen for those with advanced disease. Complications include bronchitis, pneumonia and lung cancer. See: emphysema.

| congenital absence of pulmonary valve | <radiology> BIG central pulmonary arteries, big RV (12 Dec 1998) |
| congenital pulmonary arteriovenous fistula | Abnormal congenital communication between pulmonary arteries and veins usually found in the lung parenchyma. (05 Mar 2000) |
| plexogenic pulmonary arteriopathy | <syndrome> Sclerosis of the pulmonary arteries in chronic cor pulmonale; associated with severe cyanosis, it is a condition resembling polycythemia vera but resulting from primary pulmonary arteriosclerosis or primary pulmonary hypertension and characterised by plexiform lesions of arterioles. Synonym: Ayerza's disease, cardiopathia nigra, plexogenic pulmonary arteriopathy. (05 Mar 2000) |
| postcapillary pulmonary hypertension | <radiology> Heart: LV failure, mitral stenosis, LA myxoma / thrombus, cor triatriatum, Pulmonary veins: congenital stenosis of pulmonary vein origin, mediastinal granulomata and neoplasms, idiopathic pulmonary veno-occlusive disease, anomalous pulmonary venous return (12 Dec 1998) |
