- Movie Clip 1: Three-dimensional movie image of the right ventricle
RV images were recorded with a 3D echo (Aplio i800, Cannon Medical Systems, Tokyo) while the patient was asked to hold her breath at the natural end-expiration. Six consecutive beats were recorded to create a dataset of the RV volume of one cardiac cycle. The numerical data was exported afterward as a csv file and then used, along with the pressure data, to draw an RV pressure-volume loop shown in the Figure 1.
