The National Echocardiography Database Australia (NEDA): Rationale and methodology

The National Echocardiography Database Australia (NEDA) is a new echocardiography database collecting digital measurements on both a retrospective and prospective basis. To date, echocardiographic data from 435,133 individuals (aged 61.6 +/- 17.9 years) with linkage to 59,725 all-cause deaths during a median of 40 months follow-up have been collected. These data will inform a number of initial analyses focusing on pulmonary hypertension, aortic stenosis and the role of artificial intelligence to facilitate accurate diagnoses of cardiac abnormalities.
