Results of one-year anticoagulation in patients with newly detected chronic thromboembolic pulmonary hypertension not treated with pulmonary endarterectomy.

Introduction: Currently pulmonary endarterectomy is considered the method of choice in patients with chronic thromboembolic pulmonary hypertension (CTEPH). It is not known if this option should be recommended in all suitable patients as it is highly variable with respect to prognosis. There is also doubt about selection of adequate time to refer patients with CTEPH for surgery.

[Infective endocarditis--still a great challenge. Two case reports].

We present two patients with aortic valve disease who developed acute infective endocarditis. In both patients the disease started with infection of the upper respiratory tract. The patients were treated with antibiotics due to pneumonia.

[Coronary angiography is not always helpful in differential diagnosis between perimyocarditis and myocardial infarction - four case reports].

Four males aged 17-42 years with ST-T segment changes suggesting perimyocarditis or non-Q acute myocardial infarction are presented. Coronary angiography was performed to establish the final diagnosis. Three patients had normal coronary arteries; two of them had typical clinical signs of perimyocarditis whereas the third patient had less typical changes.
