Accuracy of Handheld Echocardiography for Bedside Diagnostic Evaluation in a Tertiary Cardiology Center: Comparison with Standard Echocardiography
Key result
Handheld echocardiography by cardiology trainees showed moderate to excellent agreement with standard echocardiography, with kappa coefficients from 0.56 for wall motion to 0.81 for LV dilation.
Why the study?
Does handheld echocardiography performed by trainees accurately detect functional and morphological heart abnormalities compared to standard echocardiography in admitted cardiology patients?
Population
56 consecutive patients admitted to a Cardiology Department, mean age 60.0 ± 11.9 years, 26 women.

I
Intervention
Handheld echocardiography (HHE) with B-mode capabilities only, performed by cardiology trainees
C
Comparator
Standard echocardiography (SE) performed by cardiologists with advanced training
O
Outcome
Diagnostic accuracy (Kappa coefficient, sensitivity, specificity, NPV, PPV) for detecting wall motion abnormalities, aortic valve abnormalities, mitral valve abnormalities, pericardial effusion, dilated left ventricle, and hypertrophied left ventriclesurrogate
Handheld echocardiography performed by cardiology trainees shows substantial to excellent agreement with standard echocardiography for assessing LV dimensions and valve morphology, supporting its utility as a bedside adjunct.

Giuşcă et al. (2010) conducted a cross-sectional in Cardiovascular disease (n=56). Handheld echocardiography (HHE) by cardiology trainees vs. Standard echocardiography (SE) by cardiologists was evaluated on Agreement (Kappa coefficient) between handheld and standard echocardiography for functional and morphological cardiac parameters. Handheld echocardiography by cardiology trainees showed moderate to excellent agreement with standard echocardiography, with kappa coefficients from 0.56 for wall motion to 0.81 for LV dilation.
