2024年10月22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.

2019年4月11日 · On the CT scan, the signs are classified into mediastinal and lung parenchymal abnormalities. In addition to suspecting the diagnosis of PH, this paper provides a pictorial essay to guide health care professionals in identifying the etiology of PH.

2022年3月29日 · Chest X-rays are among the first imaging tests that doctors perform if they suspect a person might have pulmonary hypertension. Your doctor “reads” the shading and colors on your chest X-ray to spot abnormalities that may suggest the presence of PH. Two such signs include enlarged pulmonary arteries or an enlarged right ventricle of the heart.

CXR findings that support the presence of PH include (1) cardiomegaly due to right atrial (RA) and right ventricle (RV) enlargement as evidenced by reduced retrosternal air space.

2012年11月23日 · Pulmonary hypertension is a complex pathophysiologic condition in which several clinical entities increase pressure in the pulmonary circulation, progressively impairing cardiopulmonary function and, if untreated, causing right ventricular failure.

One essential component of the initial patient workup for pulmonary arterial hypertension (PAH) is the need to obtain a radiographic assessment of the lungs. This is done in conjunction with a detailed patient history, ECG, and physical exam.

Pulmonary hypertension is defined as an increase in mean pulmonary arterial pressure ≥25 mm Hg at rest and occurs in a majority of patients with heart failure. Diagnostic imaging targets the right ventricle and the pulmonary vasculature.

2018年1月10日 · Group 4 is caused by chronic thromboembolic pulmonary hypertension (CTEPH) and other diseases of pulmonary artery obstruction such as neoplasms, congenital pulmonary artery stenosis, arteritis, and hydatid cyst (6). Group 5 involves miscellaneous entities with unclear and multi-factorial mechanisms. Table 1.

2017年1月14日 · Severe pulmonary hypertension on CXR: X-Ray chest PA view showing features of severe pulmonary hypertension. There is mild cardiac enlargement with prominence of the right atrial contour (RA), which is extending more to the right than usual.

To confirm the diagnosis, several exams are conducted, with “diagnostic imaging targeting the right ventricle and the pulmonary vasculature,” as explained in the study “ Imaging in Pulmonary Hypertension.” It is in this diagnostic approach that chest …
