[Silent myocardial ischemia before and after revascularization].

In 82 patients with unstable ischemic heart disease (IHD) before and after revascularisation (percutaneous transluminal coronary angioplasty-PTCA-in 11 patients and coronary artery bypass graft-CABG-in 71 patients) silent ischemia incidence was observed. In these patients before and after operation election fraction (EF) and wall motion score index (IK) were compared echocardiographically as well as physical ability according to Bruce protocol in treadmill exercise test. Data (EF and IK and exercise test) before and after operation didn't change significantly.

[Metastatic neoplasms of the heart].

Two cases are presented of metastatic neoplasm of the heart easy for echocardiographic diagnosis. One infiltrated the pericardium with encapsulated fluid (visible also on X-ray), and the other was associated with filling of the right atrial lumen.

[Leukemic changes in the myocardium of a patient with acquired valvular heart disease].

A rare case is described of extensive myocardial infiltrations during myeloid leukaemia in a patient with coexistent valvular heart disease, and active inflammatory process in the endocardium. The coexistence of these diseases caused even greater diagnostic difficulties. This case shows also that differential white blood cell sound should not be disregarded in cardiovascular diseases.

[Diagnostic difficulties in a case of intracardiac tumor].

64 years old female operated on for right auricular tumor, which manifested as right ventricular heart failure is presented. Although full preoperative diagnostics was performed the tumor appeared to be metastatic one with the primary focus situated in the liver (histologically ca hepatocellular). Necessity of cavography in case of right auricular tumor is stressed in the paper.

[A case of isolated, corrected transposition of great arteries diagnosed with non-invasive techniques].

A case of a 34-year female patient with the isolated transposition of the great arterial trunks and mild atrioventricular (tricuspid) valve insufficiency is presented. The disease was diagnosed with non-invasive technique, particularly echocardiography. Cardiac disorders being usually concomitant with this syndrome (interventricular leak, pulmonary arterial wedge stenosis etc.
