Acheampong B, Parra DA, Aliyu MH, Moon TD, Soslow JH. Smartphone interfaced handheld echocardiography for focused assessment of ventricular function and structure in children: A pilot study. Echocardiography (Mount Kisco, N.Y.). 2020 Jan;37(37). 96-103. PMID: 31879998 [PubMed]
Miniaturized echocardiographic machines improve availability and portability and can be particularly useful for underserved and resource-limited settings. The goal of this study was to compare left ventricular fractional shortening (FS) and left ventricular ejection fraction (LVEF) obtained by a newer handheld echo (HHE) machine to standard transthoracic echocardiogram (TTE) in children.
