Pulmonary arterial hypertension is defined as a mean pulmonary arterial pressure >25 mmHg at rest 11 or >30 mmHg with exercise and pulmonary capillary wedge pressure ≤15 mmHg measured by cardiac catheterization 3,4 Pulmonary arterial hypertension is defined as a mean pulmonary arterial pressure >25 mmHg at rest 11 or >30 mmHg with exercise and pulmonary capillary wedge pressure ≤15 mmHg measured by cardiac catheterisation 3,4 Pulmonary hypertension is defined as a resting mean pulmonary arterial pressure of 25 mmHg or more at catheterization of the right side of the heart, a hemodynamic feature that is shared by all types of pulmonary hypertension in the Dana Point classification system (Table 1) This was a case of idiopathic pulmonary arterial hypertension. In an exam look for common causes of Pulmonary hypertension such as: pulmonary parenchymal disease (pulmonary fibrosis, emphysema, cystic fibrosis) pulmonary vessels ( chronic pulmonary thromboembolism) cardiac (L>R shunts, mitral stenosis) connective tissue disorders ( Scleroderma.

Pulmonary arterial hypertension (PAH) is defined as a mean pulmonary arterial pressure of greater than 25 mm Hg at rest or 30 mm Hg with exercise, with an elevated pulmonary vascular resistance (PVR) greater than 3 Wood units Pulmonary arterial hypertension is defined as a mean pulmonary artery pressure exceeding 25 mm Hg (3300 pascals [Pa]) at rest or 30 mm Hg (4000 Pa) with exercise. The pathologic changes are largely confined to the muscular pulmonary arteries that measure less than 1 mm in diameter Pulmonary hypertension (PH) is defined by a mean pulmonary artery pressure greater than 20 mm Hg and classified into five different groups sharing similar pathophysiologic mechanisms, hemodynamic characteristics, and therapeutic management. Radiologists play a key role in the multidisciplinary assessment and management of PH Pulmonary hypertension is hemodynamically defined as a mean pulmonary artery pressure greater than 25 mm Hg at rest or greater than 30 mm Hg during exercise with an increased pulmonary vascular resistance (1, 2). This condition may be caused by a wide variety of disease entities with overlapping radiologic-histologic features Chest radiographs are abnormal in 90% of patients with idiopathic pulmonary arterial hypertension (PAH) at the time of diagnosis (4). Chest radiography may help assess the presence of PH, but the degree of PH does not correlate with the extent of imaging abnormalities, and chest radiography is rarely used as the sole imaging modality (4)

Pulmonary hypertension Radiology Reference Article

  1. Imaging plays a central role in the diagnosis and management of all forms of pulmonary hypertension (PH). Although Doppler echocardiography is essential for the evaluation of PH, its ability to optimally evaluate the right ventricle and pulmonary vasculature is limited by its 2-dimensional planar capabilities
  2. Pulmonary arterial hypertension (PAH) is characterized by vasoconstriction and progressive vascular remodeling of small pulmonary arteries that lead to a progressive increase in pulmonary vascular resistance (PVR) and right ventricular (RV) remodeling.1 Non-segmental defects as ''mottled pattern'' or ''patchy pattern'' on lung perfusion are occasionally seen in PAH patients.2.
