[Radiographic assessment of pulmonary hypertension: Methodical aspects].

Pulmonary hypertension is a menacing complication of a number of diseases, which is responsible for high mortality rates and considerably poorer quality of life in a patient. The timely detection for pulmonary hypertension allows timely initiation of treatment, thus improvement in prognosis in the patient. Chest X-ray is the most commonly used radiographic technique for various causes.

[Age-related diagnostic features of congenital atrial septal defect in adults according to the data of radiodiagnostic studies].

Objective: To reveal diagnostic features in atrial septal defect (ASD) in different age groups; to define a role of X-ray study in the diagnosis of ASD.

Material And Methods: Forty-eight patients (16 men and 32 women) aged 15 to 71 years with ASD at different sites were examined. All the patients underwent chest X-ray, echocardiography, and cardiac phase-contrast magnetic resonance imaging (MRI).

[Using nonselective endothelin receptor antagonist in idiopathic pulmonary hypertension].

Idiopathic (primary) pulmonary hypertension (IPH) is a rare disease of unknown etiology, which is characterized by elevated pulmonary artery pressure, increased total pulmonary vascular resistance, frequently a malignant course with evolving right ventricular decompensation, and a fatal outcome. The diagnosis of IPH is established on the increments in the mean resting and exercise pulmonary artery trunk pressure by more than 25 and more than 30 mm Hg at rest and during exercise, respectively, with a normal pulmonary artery wedge pressure. Endothelin receptor antagonists (ERA) are one of the effective classes of drugs for the treatment of patients with IPH.

[Pulmonary venous occlusive disease].

The present study deals with the radiation diagnosis of the rare disease--pulmonary venous occlusive disease. The follow-up covered three cases that ended with death. The clinical picture of the disease did not differ from the manifestations of primary pulmonary hypertension.
