Key result
Pocket-size echographs (Vscan) demonstrated excellent agreement with high-end echocardiographs for left ventricular systolic function (Kappa 0.89) and pericardial effusion (Kappa 0.81).
Why the study?
Does a pocket-size handheld echocardiograph provide comparable diagnostic accuracy to a high-end standard echocardiograph in patients requiring urgent echocardiography?
Population
104 consecutive patients requiring urgent echocardiography in the acute care setting.
Comparison
Pocket-size handheld echocardiograph performed… vs High-end standard echocardiograph.
Design
Cross-sectional, blinded manner (for comparison of exams)

Does a pocket-size handheld echocardiograph provide comparable diagnostic accuracy to a high-end standard echocardiograph in patients requiring urgent echocardiography?
Effect estimate: Kappa: 0.89 and 0.81
Pocket-size handheld echocardiographs used by trained cardiologists offer good diagnostic accuracy for key parameters in the acute care setting compared to standard high-end machines.
Testuz et al. (2012) conducted a cross-sectional in Acute cardiac care requiring urgent echocardiogram (n=104). Pocket-size echograph (Vscan) vs. High-end standard echocardiograph was evaluated on Agreement for left ventricular systolic function and pericardial effusion (Kappa: 0.89 and 0.81). Pocket-size echographs (Vscan) demonstrated excellent agreement with high-end echocardiographs for left ventricular systolic function (Kappa 0.89) and pericardial effusion (Kappa 0.81).
