| Abstract:: |
| Objective To compare the relative accuracy of three methods measuring left ventricular volume by X-ray ventriculography:single plane area-length method, biplane area-length method, and single-plane Simpson's method. Methods Left ventricular casts were obtained within 24 hours after death from 12 persons who died from non-cardiac causes. The true left ventricular cast volume was measured by water displacement. The calculated volume of the casts was obtained with 3 angiographic methods, i.e., single-plane area-length method, biplane area-length method, and single-plane Simpson's method.Results The actual average volume of left ventricular casts was (61.17±26.49) ml. The left ventricular volume was averagely (97.50±35.56) ml with single plane area-length method, (90.51±36.33) ml with biplane area-length method, and (65.00±23.63) ml with single-plane Simpson's method. The left ventricular volumes calculated with single-planeand biplane area-length method were significantly larger than that the actual volumes (P<0.05), but there were no significant differences between the actual volumes and those calculated with single-plane Simpson's method (P>0.05). The left ventricular volumes calculated with single-plane and biplane area-length method were significantly larger than those calculated with single-plane Simpson's method (P<0.05). There were no significant differences between volumes calculated with single-plane and with biplane area-length methods (P>0.05). The overestimation of left ventricular volume by single plane area-length method (36.34±17.98) ml and biplane area-length method (29.34±15.59) ml was more obvious than that calculated by single-plane Simpson's method (3.83±8.48) ml. Linear regression analysis showed that there was close correlations between left ventricular volumes calculated with single plane area-length method, biplane area-length method, Simpson's method and the true volume(all r >0.98).Conclusion Single-plane Simpson's method is more accurate than single plane area-length method and biplane area-length method for left ventricular volume measurement; however, both the single-plane and biplane area-length methods could be used in clinical practice, especially in those imaging modality without sophisticated software. |
