Miniaturisation of ultrasound equipment in the form of a tablet- or smartphone-sized scanner is the result of rapid development of modern medical technology. Availability of mobile ultrasound devices has changed our approach to diagnostics of many cardiovascular diseases. Mobile visualisation can be performed at the patient’s bedside and is simple in use. The information obtained from mobile visualisation, despite being incomplete, is of undoubtable value for rapid diagnosis which leads to early treatment onset. These devices possess unique characteristics: low cost, wide availability, safety, and precision. These characteristics make them usable in different clinical scenarios by operators of different specialties and expertise. Visualisation and interpretation of the images is done fast and provides useful diagnostic, prognostic and treatment data for each situation. This review devotes main attention to the regulation of application of mobile ultrasound devices, the notion of “focus cardiac ultrasound” and its differences from emergency and elective expert echocardiography protocols as well as limitations and numerous advantages related to usage of mobile ultrasound systems.
