This study validates a reconstructive technique that describes 3-dimensional right ventricular (RV) shape and volume with the use of 3 standard echocardiographic planes. The volume of 24 cast models of lamb right ventricles (12 normal, 12 hypertensive) was determined by water displacement. Reconstruction of the cast shapes was calculated from 2 sets of digitized data: cast cross-sectional digitized tracings and echocardiographic cross-sectional tracings. Regional volume ratios from both data sets were assessed to quantitatively specify RV regional volume differences between normotensive and hypertensive right ventricles. This method described the 3-dimensional RV shape with no differences between reconstructed volumes and true volumes for either normotensive or hypertensive casts. Between hypertensive and normal groups, regional volume ratios yielded a difference in free wall ratios that was observed to be greater in the hypertensive cast group (P =.007). |
