15 16 Automatic measurement of LV EF (autoEF) from apical HUD recordings are now commercially available, and a novel method for real-time automatic measurement of MAPSE (autoMAPSE) is available on the GE Vscan Extend (GE Ultrasound, Horten, Norway) for research purposes. 11–15 The experience and skill of the operator is essential for more advanced measures such as assessment of LV function. 10 Several studies have shown high feasibility and reliability for inexperienced users performing simple tasks by HUDs. 9 So far, quantification of LV size and function by HUDs has relied on visual evaluation only. Hand-held ultrasound devices (HUD) have been widely implemented in the medical field over the last decade and are increasingly used by non-experts. Semi-automatic quantification of LV EF has been available for some time, but automatic quantification of MAPSE is not widely available. 5 Another robust and easily obtainable measure of LV function is mitral annular plane systolic excursion (MAPSE), which is quite sensitive for detection of LV dysfunction, 6–8 even when EF is preserved. 4Įstimation of left ventricular (LV) ejection fraction (EF) is required for classification and treatment of HF. 3 Moreover, it is shown that a delayed HF diagnosis may be present in up to 40% of patients. HF may be challenging to diagnose and it is shown that (in-training) cardiology fellows inaccurately interpret echocardiograms. 1 2 Echocardiography is the cornerstone imaging modality for HF diagnostics and patient follow-up. Heart failure (HF) is a severe condition with poor prognosis and reduced quality of life which constitutes a burden on the healthcare system with high costs and 26 million patients affected worldwide.
