[Clinico-roentgenological characteristics of thromboembolism of the pulmonary arteries in patients with rheumatism].

The authors have analyzed 31 patients (10.2% of the total number of patients with rheumatic fever) to reveal the clinical and roentgenological signs of thromboembolism of the pulmonary arteries. Conditions for the development of pulmonary thromboembolism, peculiarities of its clinical picture and course have been described; attention has been drawn to the roentgenological signs of pulmonary occlusion. The authors believe that the definition of the 5 main pathogenetic variants of a course of thromboembolism of the pulmonary arteries in patients with rheumatic fever can serve as the basis for early diagnosis.

[Clinico-x-ray diagnosis of pneumonia in acute myocardial infarction].

The report presents the findings from a clinical-roentgenologic study of 814 patients with acute myocardial infarction. The myocardial infarction was complicated by pneumonia in 82 (10.7%) patients including 53 cases of hypostatic, and 6 cases of atelectatic forms of pneumonia. The remaining 23 patients presented an exacerbation of chronic pneumonia. In 61 patients (77.0%) pneumonia was associated with venous congestion and 50% of these patients showed interstitial or alveolar pulmonary edema. The diagnosis of pneumonia is shown to be possible on the basis of clinical and roentgenologic signs.

[Differential clinico-xray diagnosis of pneumonia and thromboembolism of the pulmonary arteries in patients with acute cerebral vascular lesions].

The results of clinical and radiological examination of 363 patients with acute brain vascular diseases are analyzed. The underlying disease was complicated by pneumonia in 50 (13,7%) patients and by pulmonary artery thromboembolism in 25 (6,8%) patients. Clinical and radiological possibilities of differential diagnosis between pneumonia and pulmonary occlusion are shown.

[State of the left-cardiac cavities after mitral valve prosthesis].

The article discusses the results of dynamic X-ray examination of the left heart cavities in 86 patients who underwent mitral valve prosthetics for mitral valvular disease. The follow-up period was 42 months. The left-ventricular volume was measured by a special method. It was established that positive time course of the left heart cavities in patients with the sinus rhythm is encountered in 1-3 months after the operation, and by the end of the first year the left cavities are stabilized and often attain their normal size. In patients with cardiac fibrillation, the left heart cavities decrease in size less frequently and at later periods, and total normalization does not occur.

[Systolic shift of the right ventricle base in patients with defects of the tricuspid valve].

A study of cinocardioangiograms taken in 29 patients (11-with "pure" tricuspidal insufficiency, 11-with a combined tricuspidal defect and 7-without any disturbances of the intracardiac hemodynamics, all of whom being examined for affections of the lungs and mediastinum) brought evidence that during the systole there occurred an intensive shifting of the right ventricle base (0.5-3 cm, the normal figure being 0.3-0.5 cm). This shift is caused by an increased stroke volume of the right ventricle due to regurgitation and high pulmonary arterial hypertension.
