Relationship Between Image Quality and Bias in 3D Echocardiographic Measures: Data From the SABRE (Southall and Brent Revisited) Study.

ABSTRACT: Background Image-quality (IQ) compromises left ventricle assessment by 3-dimensional echocardiography (3DE). Sicker/frailer patients often have suboptimal IQ, and therefore observed associations may be biased by IQ. We investigated its effect in an observational study of older people and when IQ was modified experimentally in healthy volunteers. Methods and Results 3DE feasibility by IQ was assessed in 1294 individuals who attended the second wave of the Southall and Brent Revisited study and was compared with 2-dimensional (2D)-echocardiography feasibility in 147 individuals. Upon successful analysis, means of ejection fraction (3D-EF) and global longitudinal strain (3D-GLS) (plus 2D-EF) were compared in individuals with poor versus good IQ. In 2 studies of healthy participants, 3DE-IQ wa
