Most publication are basing RV volumes on images acquired from the apical window. However, some data have called the practice of basing these images on apical window into question. Moreover, despite our best efforts, we have been unable, in our laboratory to reliably visualize RV outflow from the apical view. Therefore, with an identified group of trained sonographers, we plan to conduct a head-to-head comparison of RV volumes acquired from these two windows (apical and subcostal), with comparison to gold-standard CMR.
