Single plane cineangiography accurately assessed left ventricular volumes, demonstrating significantly reduced ejection fraction and ejection rate in patients with cardiomyopathy.
Observational
Single plane cineangiography, either in the anteroposterior or in the right anterior oblique pro- jection, can be used to determine left ventricular volumes. Volumes so obtained showed good agreement with those reported by others using biplane techniques. Ejection fraction and ejection rate derived from such volumes were normal in patients with mitral stenosis and with chronic compensated pressure and volume overloads, but were significantly reduced in patients with cardiomyopathy. Unlike ejection fraction and ejection rate, left ventricular end-diastolic pressure was not found to be a sensitive index for differentiating patients with and without left ventricular dysfunction.
Chatterjee et al. (Thu,) conducted a observational in Left ventricular dysfunction. Single plane cineangiography vs. Biplane techniques was evaluated on Left ventricular volumes, ejection fraction, and ejection rate. Single plane cineangiography accurately assessed left ventricular volumes, demonstrating significantly reduced ejection fraction and ejection rate in patients with cardiomyopathy.
