Measurement of Stroke Volume With Echocardiography Compared to Gold Standard Cardiac Magnetic Resonance Imaging: An Observational Study

J Cardiothorac Vasc AnesthPublished Method comparison study

Authors' conclusion

Of the 4 echocardiographic LV stroke volume measurement methods the authors assessed, stroke volume with LVOT Doppler using 3D measurement of LVOT area most closely approximates gold standard CMR.

Study context

Population
Volunteers free of known structural heart disease, medical research institute
Participants
187 volunteers
Exposure
4 TTE stroke volume techniques vs gold standard CMR
Outcome
Agreement of left ventricular (LV) stroke volume by TTE (2D and 3D Doppler and volumetric techniques) with gold standard CMR
Methodological detailsobservational
  • Observational

Main finding

As reported in the abstract

Bias vs CMR
All TTE techniques underestimated stroke volume vs CMR
P < 0.001

Observational data: associations, not effects.
