[Camera-cinematography of the heart (author's transl)].

By "camera-cinematography" of the heart, we mean an isotope method which permits detailed observation of cardiac mechanics without the use of a catheter. All that is necessary is an intravenous injection of 10 to 15 mCi 99mTc human serum albumen followed after ten minutes by a five to ten minute period of observation with a scintilation camera. At this time the isotope has become distributed in the blood. Variations in the precordial impulses correspond with intra-cardiac changes of blood volume during a cardiac cycle. Analysis of the R-wave provides adequate information of cyclical volume changes in limited portions of the heart. This is achieved by a monitor with a pseudo-3-dimensional display; contraction and relaxation of the myocardium can be shown for any chosen longitudinal or horizontal diameter of the heart. Our programme allows simultaneous presentation of the movement of any point on the myocardium as a time-activity curve. The method is recommended as an addition to chest radiography, heart screening or cardiac kymography before carrying out cardiac catheterisation.

[Transvenous cardiography and pulmonalis angiography for differentiating between pathologic mediastinal shadows (author's transl)].

A technique of contrast-medium radiology of cardiac cavities and the great vessels without catheter is described. The contrast-medium (30 ml) is injected rapidly and bilaterally into the cubital veins. This is sufficient to differentiate between pathologic changes in the mediastinum of vascular of non-vascular origin and between pericardial effusion and myogenous cardiac dilation. The effectiveness of this not demanding technique is discussed on 4 cases. The risks of this investigation are not greater than those of any other method using larger amounts of contrast medium without general anesthesia.
