[Coronary flow measurements, using cine densitometry. Results using a multiple detector method. I. Normal flow values in healthy and stenosed coronary arteries during rest (author's transl)].

Coronary blood flow was measured by a cine densitometric method using a newly developed system incorporating computer data analysis. The first results concerning front and wave velocity of a selectively injected contrast bolus are reported. Average absolute flow volumes in the right coronary artery are 114 ml. per minute, in the left coronary artery, 88 ml per minute (RIVA = 52 ml/min., RC = ml/min.). There is good agreement with the results of dye dilution and isotope wash out techniques, but the latter are more complicated and less easily reproduced and therefore less suitable for routine use. The results are critically evaluated.

[Percutaneous removal of a guide wire from the right ventricle and pulmonary artery (author's transl)].

Successful removal of an opaque guide-wire from the right ventricle and left pulmonary artery is reported. The wire was extracted into the right external iliac and common femoral vein and then removed by a venotomy. Percutaneous removal of embolised foreign bodies should be carried out as soon as possible. An attempt at percutaneous removal is to be preferred to a thoracotomy because of the considerably reduced risk.

[Changes in serum osmolarity after high contrast doses during angiography].

Analysis of changes in osmolarity of the serum after various doses of hypertonic radiographic contrast media, following a single injection, showed an initial rise of about 35 m/mosm/1, followed by a rapid fall in osmolarity with a subsequent short hypo-osmolar phase. With repeated injections, similar changes are found if the intervals between the injections are long enough. Following repeated injections over a short interval, there may be a more prolonged phase of hyperosmolarity. In this phase of delayed dehydration, there may be clinical complications. Possible forms of treatment are discussed.

[The accuracy of surface kymography following myocardial infarcts, with special reference of cardiac aneurysms (author's transl)].

Surface kymography in three planes were performed in 180 patients following myocardial infarcts, and these were compared with the results of coronary angiography and selective laevocardiography. Kymography performed for the diagnosis of cardiac aneurysms and myocardial scars is relatively accurate (53%), as shown by a comparison with the laevocardiograms. Of the aneurysms demonstrated by laevocardiography in the left ventricle (31), it was possible to show 22 (71%) kymographically. In order to achieve these results, it is necessary to examine at least three marginal contours of the left ventricle by kymography (left heart border, anterior and posterior wall). The routine use of kymography before employing invasive techniques provides useful information regarding the optimal plane of the laevocardiogram. Furthermore, it indicates the presence of myocardial disease and the need for further investigation.

[On the reliable visualization of digital arteries as recorded by arteriography applying only local anesthesia and alcoholic drink (author's transl)].

Reliable visualization of arteries in hands, fingers, feet and toes largely depends on the tone of peripheral vessels. This can be lowered by general anesthesia but also under local anesthesia if local warming and oral Alcohol are added. Differential diagnosis between organic and functional disturbances of circulation is guaranteed in this way. Digital arteries can be well shown right down to the tips of fingers and toes.
