Postprocessing for quantification of RV volumes and function using offline 3D echocardiographic analysis software. (1) Data alignment to identify the RV long axis. (2) Define landmarks. (3) Software was used to automatically extract the 3D endocardial surface. (4) A 3D model of the RV was generated. RV: right ventricle; 4Ch: four-chamber view; SAX: short-axis
