Observational (n=32)
Does a new method using three axial dimensions from biplane right ventriculography accurately estimate right ventricular volume and ejection fraction compared to Simpson's method in patients?
A new method using three axial dimensions from biplane right ventriculography provides right ventricular volume and ejection fraction estimates that correlate well with Simpson's method.
The aim of the present study was to establish a new method to evaluate the right ventricular dimensions and volume. Biplane right ventriculography of steep left anterior oblique view (LAO) and right anterior oblique view perpendicular to LAO were performed in 32 patients. The right ventricular volume and ejection fraction calculated from the three axial dimensions of the right ventricular cavity (the septum-free wall dimension, the anterior-posterior dimension, and either the long axis dimension or the tricuspid valve-apex dimension at end-diastole and end-systole) were well correlated to those from Simpson's method. In conclusion, we developed a new method for estimating right ventricular dimensions and volume.
Ishigaki et al. (Mon,) reported a observational. Three axial dimensions method from biplane right ventriculography vs. Simpson's method was evaluated on Correlation of right ventricular volume and ejection fraction. A new method calculating right ventricular volume and ejection fraction from three axial dimensions using biplane right ventriculography correlated well with Simpson's method.
