in order to compare biplane left ventricular cast volume determinations from orthogonal and nonorthogonal axial oblique and standard orthogonal oblique cineangiograms to those that were obtained by water ( h2o ) displacement , we evaluated 14 human heart specimens in the following projections : 30-degree right anterior oblique and 60-degree left anterior oblique/20-degree cranial ( lva ) , 45-degree left posterior oblique and 60-degree left anterior oblique/30-degree cranial ( lvb ) , and 30-degree right anterior oblique and 60-degree left anterior oblique ( lvc ) .
