[Angiography of the left ventricle using right atrial injection (author's transl)].

Left ventricular angiography as a diagnostic means is of considerable importance in the evaluation of myocardial and valvular dynamics. The injection of contrast medium into the left ventricle often causes premature ventricular contractions. In these cases quantitative analysis of the contraction pattern is impossible. This can be avoided by injection of the contrast medium into the right atrium. The technique described allows to obtain ventriculograms which meet the criteria for quantitative angiocardiography. 57 ventriculograms have been performed in 32 patients with various cardiac abnormalities. The study describes the technical procedure, the indications and limitations. Furthermore special applications are discussed (videometry, pressure-volume relationship).
