Accuracy and Efficacy of Hand-Held Echocardiography in Diagnosing Valve Disease: A Systematic Review.

In recent years, advances in technology have enabled hand-held echocardiography (HHE) to generate high-quality 2-dimensional and color Doppler images. As these devices become smaller, simpler, and more affordable, the question of whether HHE can augment or replace auscultation as the primary mode of cardiovascular diagnosis has become increasingly more relevant. If widely implemented, HHE has the potential for significant cost savings and better resource utilization. This review examines studies comparing the sensitivities of auscultation, HHE, and standard echocardiography in detecting various valvular lesions and discusses why current evidence supports the use of HHE to augment the physical examination, which can lead to more reliable and rapid bedside diagnoses, triage, and appropriate treatment of structural cardiac abnormalities.
