#MAPSE: an unappreciated treasure for assessing LV function? #EchoFirst #WhyCMR
#MAPSE is easy and feasible in almost every patient, also in #ICU. It is highly prognostic, yet unpopular. The reasons are not rational.

...during that era, physiologists were focused on cardiac pressure/volume relationships. LVEF emerged as a metric reflecting cardiac volumes, thus filling an unmet need.

Then, #EchoFirst for assessing LVEF then became available. #MAPSE was shown early to correlate with LVEF. However, it was only considered a "quick and dirty" surrogate of LVEF.

The limitations of LVEF then became strikingly obvious, as patients with heart failure but preserved LVEF had similar prognosis as reduced LVEF.

Meanwhile, #MAPSE had shown prognostic value already in 1997.

However, this was also the time when GLS by speckle-tracking #EchoFirst emerged as a metric of LV function.
Speckle-tracking was a huge technological trend, and still is. #MAPSE relies on simple M-mode, lacking the "WOW!"-factor and thus overlooked.doi.org/10.1016/j.echo…

The assumed superiority of GLS was recently challenged. In a head-to-head study using #WhyCMR, MAPSE had better prognostic ability than GLS and LVEF.😎

Finally, because #MAPSE is works even when image quality is poor, it is available for automatic monitoring, especially with TEE. #AutoMAPSE

To conclude, #MAPSE is a classical parameter of LV function that has been overshadowed by technological trends. MAPSE is easy to master by anyone doing #POCUS and #EchoFirst.
Imagine how medicine would be different if MAPSE was a standard parameter since 1967?
