Comparison of 3 hand-carried ultrasound devices with comprehensive echocardiographic devices in elderly cardiac inpatient examinations / 中国医疗器械杂志

ABSTRACT

In order to test the clinical capacity of hand-carried ultrasound (HCU) devices in elderly inpatients with heart disease, chamber sizes of heart structure, ventricular wall thickness and motion abnormality (WMA), mitral valve and tricuspid regurgitation evaluated by HCU devices in 401 elderly inpatients with heart disease were compared with those evaluated by comprehensive echocardiography (CE) devices. As a result, there was no significant difference in measurements of cardiac chamber dimensions or left ventricular ejection fraction between the two techniques. The HCU's WMA detection rate relative to the CE was 92.15%. Their conformable rates for detection of mitral and tricuspid regurgitation was 93% and 91.4% respectively. Therefore, we conclude that HCU is one of the practical modalities for diagnosis and monitoring in elderly inpatients with heart disease.
