Angiographic Evaluation of Ventricular Function

Angiographic visualization of the left ventricle makes it possible to determine left-ventricular-chamber dimensions, volume, stroke volume, wall thickness, mass and characteristics of regional wall motion. This information is of value for clinical assessment of the performance characteristics of the left ventricle in man with heart disease.Although the original methods for computing leftventricular-chamber volumes were based on biplane filming, and these methods seem to be the most accurate, methods are now available for computing volumes from large films or from cineangiograms taken in single anteroposterior or right-anterior-oblique projections as well. For computing volumes, the most commonly used methods have used . . .
