ABSTRACT
<p><b>OBJECTIVE</b>To study the validity of single plane Simpson's method with conventional X-ray ventriculography for estimation of right ventricular (RV) volume.</p><p><b>METHODS</b>Fifteen human RV casts were obtained from 15 subjects who died from non-cardiac causes within 24 hours after death. These casts were photographed respectively and their volumes were calculated by using the single plane Simpson's method based on a new half-circle model. The actual RV cast volumes were determined by water displacement method.</p><p><b>RESULTS</b>The actual RV volume was (64.23 +/- 24.51) ml and the calculated volume was (58.04 +/- 24.45) ml. The calculated RV volume underestimated the actual volume by (6.19 +/- 12.38) ml, but there was no significant difference between the actual and the calculated RV volume (P > 0.05). There was a significant correlation between the actual cast volume and the calculated volume (r = 0.983, P < 0.01). The regression equation was RV actual volume = 1.074 x (RV calculated volume).</p><p><b>CONCLUSION</b>RV volume calculated by single plane Simpson's method with conventional X-ray ventriculography is accurate and deserves further study.</p>
