Value of ventriculography in cardiac function and diagnosis.
The methods for calculating left ventricular volumes employing biplane angiocardiograms and the calculated parameters of left ventricular mass, pressure-volume diagrams, wall forces, compliance, and abnormally contracting segments are described. Examples of these calculations are given and the contributions to the assessment of cardiac function and diagnosis are discussed. Normal values and the alterations produced by volume overload, pressure overload, myocardial disease, and coronary artery disease are presented.
