Angiocardiography can accurately measure and demonstrate the equivalence of right and left ventricular stroke volumes in patients without shunts or regurgitation when corrected for filling time.
Answers are grounded in this paper and cite their sources.
Angiographic biventricular stroke-volume equivalence after filling-time correction supports method validity in select patients; leaves open validation in shunts or regurgitation.
An angiocardiographic method for measurement of right and left ventricular volume, described earlier, has been applied for comparison of right and left ventricular stroke volumes in 17 patients. These patients had no shunts or regurgitant valve lesions that would alter the equivalence of the ventricular stroke volumes. The angiographic measurements give essentially equal volumes for left and right ventricular stroke volumes when the right ventricular stroke volumes are subjected to a linear correction for filling time.
