The contour of the pulmonary artery wedge pressure tracing in a case of pulmonary venous obstruction was unique and may be diagnostic. Wedged pressures were obtained in both a pulmonary artery and a pulmonary vein on recatheterization of a 5-yearold boy with total anomalous pulmonary venous drainage to the superior vena cava on whom an anastomosis of the confluence of the pulmonary veins to the...

CONTEXT AND OBJECTIVE The location of embolism is associated with clinical findings and disease severity in cases of acute pulmonary embolism. The level of gamma-glutamyl transferase increases under oxidative stress-related conditions. In this study, we investigated whether gamma-glutamyl transferase levels could predict the location of pulmonary embolism. DESIGN AND SETTING Hospital-based cr...

Background The outcome of the Fontan operation largely depends on patient selection because this procedure is a physiological correction. Among the several selection criteria for the Fontan operation, the importance of adequate size of the pulmonary artery remains controversial. To clarify whether or not pulmonary artery size is indispensable as one of the selection criteria for the Fontan oper...

A new measurement of the pulmonary artery diameter is obtained where the artery may be robustly segmented between the heart and the artery bifurcation. An automated algorithm is presented that can make this pulmonary artery measurement in low-dose non-contrast chest CT images. The algorithm uses a cylinder matching method following geometric constraints obtained from other adjacent organs that ...

{4-[(5,6-Diphenylpyrazin-2-yl)(isopropyl)amino]butoxy}acetic acid (ACT-333679) is the main metabolite of the selective prostacyclin (PGI2) receptor (IP receptor) agonist selexipag. The goal of this study was to determine the influence of IP receptor selectivity on the vasorelaxant efficacy of ACT-333679 and the PGI2 analog treprostinil in pulmonary artery under conditions associated with pulmon...

Angiosarcoma arising in the pulmonary artery is extremely rare. We herein report a case of angiosarcoma arising in the pulmonary artery trunk of 71 year-old woman. This case was clinically diagnosed as pulmonary thromboembolism but angiosarcoma of the pulmonary artery should be considered as the differential diagnosis of unusual clinical manifestations of pulmonary thromboembolism because of th...
