title: [Hand-held echocardiography in clinical practice].
abstract: In the last years the industry has created echocardiographic portable machines of reduced size, available for a growing number of operators. After the first experiences of the '70s, hand-held echocardiography (HHE) is earned interesting commercial positions. The transportability of these machines allows to perform examinations outside the echo-lab and provides diagnostic information in heterogeneous locations such as intensive care unit, emergency room and outpatient structures, at the bedside and even in ambulance. HHE can be useful for detection of several pathologies including aortic aneurysms and left ventricular hypertrophy, regional wall motion abnormalities, pericardial and pleural effusion. To date, four main kinds of HHE can be distinguished: a first, high-cost variety, including miniaturized machines, equipped with instrumentations of standard echocardiography and even new softwares for tissue Doppler and myocardial contrast echocardiography; a second kind of machines of high level but not miniaturized; a third (intermediate level and low cost), and a fourth one (basic level and very low cost), including "cardioscopes" corresponding to the ultrasound stethoscope, able to complete efficaciously the clinical examination. The introduction of HHE opens controversy about its diagnostic accuracy, the opportunity to establish the clinical scenario where it should be utilized and the identification of the potential users and the needed competence level. Preliminary experiences show the possibility of improving and anticipating the diagnosis of several cardiac diseases but also the need to plan specific ultrasound training to avoid inappropriate use of HHE.
