Key result
Correlation between TEE-derived LVOT VTI and thermodilution SVI yields no reported results.
Why the study?
LVOT VTI is a promising surrogate for stroke volume, but controversy exists regarding its correlation with thermodilution or newer cardiac output measurement techniques.
Is there a correlation between LVOT VTI determined by TEE and SVI calculated by thermodilution in patients undergoing cardiac surgery?
Observational

Answers are grounded in this paper and cite their sources.
No results reported; leaves open whether LVOT VTI by TEE correlates with thermodilution SVI in cardiac surgery.
Left ventricular outflow tract velocity time integral (LVOT VTI) is a promising surrogate for stroke volume (SV). However, there is controversy in the literature regarding its correlation with thermodilution or newer cardiac output measurement techniques. This study was conducted to determine the correlation between LVOT VTI determined by transesophageal echocardiography (TEE) with stroke volume index (SVI) calculated by thermodilution.

Isogai et al. (2022) conducted an observational in Cardiac surgery. Left ventricular outflow tract velocity time integral (LVOT VTI) by transesophageal echocardiography vs. Stroke volume index (SVI) by thermodilution was evaluated on Correlation between LVOT VTI and SVI. The correlation between left ventricular outflow tract velocity time integral determined by TEE and stroke volume index calculated by thermodilution was investigated, but no results were reported.
