title: [Determination of global left ventricular functional parameters with intraventricular digital subtraction angiography in coronary disease].
abstract: Left heart catheterisation, coronarography and conventional angiocardiography of the left ventricle (ACG) [30 degrees right anterior oblique; 45 ml contrast medium (Visotrast) with a flow of 12 ml per sec.] was performed in 86 patients with coronary heart disease. Additionally intraventricular digital subtraction angiography (DSA) was performed, using a Philips-device (DVI 2 CV). For DSA 15 ml contrast medium (Visotrast) was injected with a flow of 8 ml per sec. 73 examinations were selected for the study. The aim of the study was to compare the usefulness and applicability of ACG und DSA for ventriculography. There were no significant differences between enddiastolic (EDV) and endsystolic (ESV) volumes as well as ejection fractions (EF) determined by ACG and DSA. Results of the analysis of correlation were rEDV = 0.85;rESV = 0.93;rEF = 0.80. The increase of the end-diastolic pressure after ACG was determined with 7 Torr (mean), after DSA with less than 2 Torr (mean). According to these results we would prefer intraventricular DSA to conventional ACG, provided the technical equipment is available. This is concluded despite the fact that in single cases considerable differences were found between the volumes estimated by ACG and those determined by DSA. These differences were analysed in detail. The main advantages of the DSA are the by far smaller inconvenience for the patients, the rare occurrence of provoked extrasystoles and the fast and easy analysis of the ventriculographies by means of the implemented image processing programmes.
