[Appropriateness in echocardiography and clinical priority classification criteria: a proposal from the Italian Society of Cardiovascular Echography].

One of the main tasks of a scientific society is to define the theoretical bases and appropriate management strategies with the aim to maintain a high-quality diagnostic and therapeutic standard. As far as echocardiography is concerned, the task of the Italian Society of Cardiovascular Echography is to provide appropriate, complete, and useful echocardiographic tests for clinical application, as well as procedural, technological, organizational and economic indications to be adopted in clinical practice. In addition, there is an increasing need for regulating access to echocardiographic assessment according to clinical priority, because of the huge proportion of patients who should undergo a first or follow-up echocardiographic evaluation.
