I want to like to ask experts in echocardiography and atrial function assessment about the following:
What is the current test and hypothetical research test that can be used to assess left atrial function in patients with atrial fibrillation?
Currently, I am working with individual segmental atrial strain, Strain rate, pulmonary vein assessment, TACT, and few other parameters. I am getting a little confused with too many emerging tests for atrial function and no clear validated test. Can someone explain to me the best few tests that can be used and potential research tests that would be able to give me a accurate assessment of left atrial function?
many thanks.
What is the opinion on TDI for left atrial function. Can the velocities also be derived from atrial strain programs such as TomTec and not only actual TDI. i.e. is tissue TDI = tissue velocities on TomTec?
I am yet to come across LA functional assessment by TDI, certainly not in BSE/EACVI/ASE guidelines. TDI could be used to asses atrial rhythm very infrequently. You can use TomTec for 3D-Reconstruction and GLS scoring, not for atrial strain as far as i am aware.
Habib I am not familiar with the reliability of established LA tests- but my modeling research into LV function indicates the LA function can be conveniently assessed from the work it does on the LV during filling. Atrial filling work is the area beneath the LV's PV loop during the filling interval. Not sure if anyone has looked at it, yet I would not be surprised to see fruitful results from a filling work index.
Dear Habib
to date, atrial strain is ongoing to be validated by large studies, whereas the greatest matter is that we use a ventricular software for measuring the atrium.
I do believe atrial reservoir will be an important marker, once a dedicated software would be available.
Yours is the occasion of proposing a multicentre trial on this, with the help of a Vendor interested in developping a tailored software.
I am willing to participate a multicentre study.
Best wishes.
