[Comparison of the diastolic mitral gradient by the methods of Doppler echocardiography and heart catheterization in patients with mitral valve defect]. / Porównanie rozkurczowego gradientu mitralnego metoda echokardiografii dopplerowskiej i cewnikowania serca u pacjentów z wada lewego ujscia zylnego.

The aim of the study was comparison of mitral diastolic gradient determination by noninvasive Doppler echocardiography and simultaneously done cardiac catheterization. The examination was performed in 34 patients with mitral valve disease, divided into 3 groups: I--isolated mitral stenosis--9 patients, II--mitral stenosis and mild or moderate mitral regurgitation (+1, +2 according to Sellers)--15 patients, III--mitral stenosis and severe mitral regurgitation (+3, +4 according to Sellers)--10 patients. In group I and II good correlation between results obtained with both methods were observed. Nevertheless, in the group III in patients with severe mitral regurgitation significantly greater mitral valve gradient was found in Doppler examination as compared to the cardiac catheterization (p less than 0.05).

[Thrombi of the left ventricle, infarction location and method of treatment]. / Skrzepliny w lewej komorze a lokalizacja zawalu i sposób leczenia.

A study is reported of 63 patients treated in the Cardiology Department, Institute of Internal Diseases, MSW for acute myocardial infarction. They were divided into two groups: 21 patients w treated with intravenous streptokinase infusion and then with intravenous heparin, with simultaneous administration of nitroglycerin. The other group comprised 42 patients treated with nitroglycerin alone. On the basis of the mass of the infarcted tissue calculated from the curves of CK-MB levels, and echocardiography for assessment of the presence of left-ventricular clots and degree of impairment of cardiac wall contractility according to Heger a much more frequent occurrence was noted of clots in the left ventricle in patients treated with nitroglycerin only, but the volume of the infarcted tissue was not statistically significantly different between both groups.
