cor pulmonale acutum
in pulmonary embolism, it occurs an important impact to the right ventricle hemodynamics, when the large part of the pulmonary arterial riverbed is obstructed by the emboli. The large territory affected by the hypoperfusion increases the right ventricle afterload and causes severe acute pulmonary arterial hypertension. The consequent hemodynamic impact to right ventricle caused the consequent increase of the right intraventricular pressure exceeding the pressure inside left one. The higher pressure on the right side than on left side is showed by the impression of the interventricular septum into the left. ventricle. The acute right ventricle overload causing bowing of the septum to the left is the sign of for pulmonate acutum
spectral analysis of the pulmonary blood perfusion volume
perfusion imaging using the tool of pulmonary blood volume is made by the spectral analysis of the data obtained by dual-time-point chest CT in the pulmonary and aortic arterial phases. Comparison of the vascular morphologic findings with thoese seen on perfusion maps improve the detection of the hemodynamic serious overload of the right ventricle
case report
64 years old female with shortened breath and chest pain, CT angiography in the pulmonary arterial and aortic phases was made. The imaging used 50 ml of the contrast material. Multiple emboli were found in the pulmonary artery an the bowing of the inter ventricular septum into the left ventricle
