Chronic Thromboembolic Pulmonary Hypertension and Assessment of Right Ventricular Function in the Piglet

[Thromboembolism of pulmonary artery branches from the right cardiac chambers]
Aim:
To reveal possible predictors of thrombosis in the right cardiac chambers and to build a mathematical model to estimate the probability of thrombi in them in patients with thromboembolism of the pulmonary artery branches.
Materials And Methods:
The data of autopsy protocols and case histories were analyzed in'157 patients in whom the source of thromboembolism had been right cardiac chambers according to postmortem evidence. A logistic regression method was used to create a probability model.
Results:
The findings were used to select 69 indicators--possible provokers of thrombosis and accordingly predictors of thrombi in the right cardiac chambers. A mathematical model--a formula to estimate the probability of thrombi in the right cardiac chambers--was made. It comprised 8 indicators: weight, height, pericardial fluid, right atrial dilatation, right ventricular wall thickness, a left or right ventricular apical scar, a concomitant inflammatory process, and concurrent diabetes mellitus. CONCLUSION; The application of the developed formula may assist in identifying a group of patients who have the highest probability of thrombi in the right cardiac chambers and accordingly must undergo a more in-depth examination.

Overview of Pulmonary Circulation
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...
