2025年1月31日 · Pulmonary hypertension is defined as a resting mean pulmonary arterial pressure of >20 mmHg at right heart catheterization, which is a hemodynamic feature that is shared by all types of pulmonary hypertension.

2025年1月31日 · Pulmonary hypertension is defined as a resting mean pulmonary arterial pressure of >20 mmHg at right heart catheterisation, which is a haemodynamic feature that is shared by all types of pulmonary hypertension.

2023年3月10日 · Pulmonary hypertension has many causes, and these can be divided in many ways. A simple and systematic approach is to proceed along the cardiopulmonary pulmonary circulation, as causes are found at each site (for a more official classification system see 2003 third world symposium on pulmonary arterial hypertension classification ).

2021年3月29日 · The differential of an enlarged pulmonary trunk/main pulmonary artery on chest radiography includes: normal. may appear prominent in young patients especially women; projectional. rotation; lordotic view; rotation of the heart. pectus excavatum; left lower lobe collapse; pulmonary arterial hypertension (PAH) pulmonary embolism; poststenotic ...

2025年1月31日 · The most common cause of pulmonary hypertension in newborns is persistent pulmonary hypertension of the newborn (PPHN). It occurs in term or late preterms infants, where the fetal shunts persist after birth and fail to close.

It is important to understand the pathophysiology involving pulmonary arterial hypertension (PAH) and how it reflects on various structures involving the pulmonary circulation. From early grades of simple dilatation of main pulmonary trunk to severe grades, as in our study wherein the high pulmonary arterial system pressure back reflects ...

Chest X-ray PA and Lateral: enlarged pulmonary trunk with associated small aortic arch, in this age group, would be in keeping with an ASD. The lungs are clear and no free sub-diaphragmatic air.

2024年5月3日 · The Eisenmenger syndrome is a complication of an uncorrected high-flow, high-pressure congenital heart anomaly leading to chronic pulmonary arterial hypertension and shunt reversal. On this page: Article:

2022年8月11日 · The Fleischner sign refers to a prominent central pulmonary artery that can be commonly caused either by pulmonary hypertension or by distension of the vessel by a large pulmonary embolus. It can be seen on chest radiographs, CT pulmonary angiography (CTPA), and MR pulmonary angiography (MRPA).

2024年5月16日 · Chronic thromboembolic pulmonary hypertension is characterised by organised tissue and the presence of a variable small vessel arteriopathy leading to an increased pulmonary vascular resistance and finally resulting in progressive right heart failure.
