Logistic regression model identifies RVD significantly better, than single CT-based measurements.

Width of the coronary sinus seems to be a promising parameter for identification of RVD in patients with acute PE. A prospective study should be undertaken to further assess its clinical and prognostic applicability.

Application of volume rendering for evaluation of right ventricle dysfunction in patients with acute pulmonary embolism diagnosed with multislice computed tomography pulmonary angiography (MSCTPA)MSCT becomes accepted imaging modality of choice in patients with suspected pulmonary embolism (PE). Increasing availability and continuous improvement of computed tomography, as well as the opportunity of making additional diagnoses, resulted in raising interest in CT pulmonary angiography ( 1 ).Right ventricle dysfunction (RVD) may result from acute PE. It results from increased pulmonary artery pressure and afterload of the right ventricle, which causes dilatation and dysfunction of the right ventricle. Such condition may cause a decreased left ventricular preload and output, which leads to hypotension and decreased coronary perfusion. Hemodynamic decompensation, however, results not only from pulmonary arteries obstruction, but also from the body reaction with multiple humoral factors, like serotonin, thrombin and histamine (2).Evaluation of PE severity and RVD determine the choice of location of therapyoriginal department, department of cardiology or pulmonology, as well as algorithm of therapy (3) and prognosis (4).
