[Morphometric and densitometric assessment of left ventricular function in the digital subtraction angiocardiogram].

The paper deals with the early clinical experience, using a new DSA installation with a specially programmed cardiological module. DSA provides very good contrast and special resolution and morphometric estimation of the ejection fraction and regional movement of the left ventricular myocardium derived from DSA. This is as good as the results of the left cardiogram. The significant advantage of DSA ist the ability to make a rapid and simple diagnosis. In addition, it is possible with densitometric methods to calculate ventricular volume curves and to provide phasic indications of the amplitude to contraction of the left ventricle. These investigations have so far proved valuable and provide new scope for the radiological evaluation of left ventricular function.
