Background: To test the diagnostic potential of the SonoHeart, a battery-powered hand-held ultrasound imaging device, in an outpatient clinic setting. Methods: A total of 114 patients with a variety of cardiac diseases were examined by 2 independent cardiologists with the hand-held device using the standard echocardiographic system (SE) as a reference. Global right ventricular (RV) and left ventricular (LV) function (scored as normal, mildly to moderately, or severely reduced) and internal cavity dimensions were assessed. Regional wall motion of 6 segments using a 2-point score (1 - normal wall motion, 2 - abnormal wall motion) was evaluated in 34 patients on-line. Results: There was a good agreement between the 2 imaging devices for evaluation of global LV (93%) and RV Junction (99%), regional wall motion (90%), dimensions of the LV (99%) and the RV (99%), and the left (96%) and right atria (99%). Furthermore, SonoHeart identified hypertrophic cardiomyopathy, pericardial effusion, and abnormalities of valves. Conclusion: The SonoHeart device allows rapid and accurate diagnosis, whenever needed in the outpatient clinic.
