The article cites a study on the pulmonary artery segment (PAS) in normal and in valvular pulmonary stenosis. Although normally the segment of the cardiac silhouette known as the PAS, is formed by the individual segment of the pulmonary artery trunk/ occasionally it can be formed by the proximal segment of the left main pulmonary artery branch, it is dilated. In most of the cases of VPS there is a dilatation of the pulmonary artery resulting in a fullness of the PAS in P-A view. In addition, and, this is very important, bulging of the PAS may be found in other diseases.

    Abstract: We present a rare case of a 44-year-old man with acquired pulmonary stenosis caused by a calcified pericardial ring. Chest computer tomography and cardiac angiography showed external compression of the main pulmonary artery by a calcified pericardial ring. A calcified pericardial ring...

    Pulmonary arteriovenous malformation (PAVM) is common after cavopulmonary anastomosis. PAVMs appear on chest X-ray film as diffuse opacity in one or both lungs. Angiographically, it appears as spidery diffuse vascularity with near simultaneous opacfication of pulmonary arteries and veins.

    Because transthoracic echocardiography is an inexpensive, easy, and reproducible method, it is the most commonly used noninvasive diagnostic tool to determine pulmonary artery pressure (PAP). Tissue Doppler imaging (TDI) emerged as a new echocardiographic method that can be applied in various...

    Scimitar syndrome consists of anomalous right lung vessel, draining often into IVC. We present a case of 34 years aged lady with recurrent pneumonia and volume loss of right lung, where CT demonstrated abnormal vessel, absence of right upper lobe bronchus, bronchiectasis in right middle lobe of...

    Idiopathic pulmonary fibrosis (IPF) can lead to the development of secondary pulmonary hypertension (PH) and ultimately death. Despite this known association, the precise mechanism of disease remains unknown. Using a rat model of IPF, we explored the role of the proangiogenic and antiapoptotic...
