Does a pocket-sized portable transthoracic echocardiographic (pTTE) device accurately measure cardiac chamber size and function compared to standard TTE in unselected patients?
A pocket-sized portable echocardiography device (Acuson P10) is highly feasible and accurate for measuring cardiac chamber size and function compared to standard echocardiography.
Effect estimate: r=0.87-0.98
p-value: p=<0.001
BACKGROUND: A pocket-sized portable transthoracic echocardiographic (pTTE) imaging device is commercially available, but its feasibility and accuracy in the assessment of cardiac chamber size and function has not been fully compared with the results of standard TTE (sTTE) examination. METHODS AND RESULTS: The target population comprised 125 unselected patients who underwent sTTE and pTTE examinations. The left ventricular (LV) diastolic and systolic dimensions, fractional shortening (FS), the thickness of the interventricular septum (IVS) and of the LV posterior wall (PWT), left atrial (LA) dimension, and ascending aorta diameter were measured. Echocardiographic measurements were completed for both pTTE and sTTE in all patients (feasibility 100%). LV dimensions, FS, IVS, PWT, LA dimension, and aorta diameter obtained by pTTE showed excellent correlation and agreement with sTTE (r=0.87-0.98, all P<0.001). Observer variabilities for these measurements were similar between pTTE and sTTE. CONCLUSIONS: In the present study, pTTE with the Acuson P10 was feasible and accurate for assessing cardiac chamber size and function.
Fukuda et al. (Thu,) conducted a cross-sectional in Patients scheduled for standard transthoracic echocardiography to evaluate left ventricular function (n=125). Pocket-sized portable transthoracic echocardiography (pTTE) device (Acuson P10) vs. Standard transthoracic echocardiography (sTTE) was evaluated on Correlation of cardiac chamber size and function measurements between pTTE and sTTE (r=0.87-0.98, p=<0.001). The pocket-sized portable transthoracic echocardiographic device demonstrated excellent correlation with standard echocardiography for assessing cardiac chamber size and function (r=0.87-0.98, P<0.001).
