Key result
Non-invasive model-based and template-based methods for LV pressure estimation correlated with invasive measurements (mean correlation coefficients 0.81 and 0.72, respectively).
Why the study?
Assessing myocardial work indices in aortic stenosis is challenging due to the need for accurate left ventricular pressure curves.
Do non-invasive model-based and template-based methods for estimating LV pressure and myocardial work correlate with invasive measurements in patients with aortic stenosis?
Observational (n=67)
Do non-invasive model-based and template-based methods for estimating LV pressure and myocardial work correlate with invasive measurements in patients with aortic stenosis?
Both model-based and template-based non-invasive methods for estimating LV pressure and myocardial work correlate well with invasive measurements in patients with aortic stenosis, with the template-based method being easier to implement for clinical practice.
May support non-invasive LV pressure estimation in aortic stenosis; leaves open prospective validation before clinical use.

Taconné et al. (2022) conducted an observational in Aortic valve stenosis (n=67). Non-invasive LV pressure estimation (model-based and template-based) vs. Invasive measurements was evaluated on Root mean square error (RMSE) and correlation with invasive measurements. Non-invasive model-based and template-based methods for LV pressure estimation correlated with invasive measurements (mean correlation coefficients 0.81 and 0.72, respectively).
