Standardised competence assessment in transthoracic echocardiography (TTE) is increasingly demanded. Danish Cardiology Society working group on echocardiography initiated a Delphi study among departments involved in resident TTE training to obtain consensus on national criteria for TTE competence. Consensus was obtained on a list of 21 items relevant for TTE competence assessment. Three items should be performed with great routine after two years and 16 items after five years of training. The working group recommends the list being used for competence assessment of cardiology residents.
