ABSTRACT
Left atrial (LA) functional analysis has an established role in assessing left ventricular diastolic function. The current standard echocardiographic parameters used to study left ventricular diastolic function include pulsed-wave Doppler mitral inflow analysis, tissue Doppler imaging measurements, and LA dimension estimation. However, the above-mentioned parameters do not directly quantify LA performance. Deformation studies using strain and strain-rate imaging to assess LA function were validated in previous research, but this technique is not currently used in routine clinical practice. This review discusses the history, importance, and pitfalls of strain technology for the analysis of LA mechanics.

Suggested strain values; A: peak systolic strain (reservoir function), B: peak early diastolic strain (conduit function), C: peak late diastolic strain, D: peak negative diastolic strain, E: time to peak systolic strain, F: early peak systolic strain rate, G: late peak systolic strain rate, H: total systolic strain rate, I: peak negative early diastolic strain rate, and J: peak positive late diastolic strain rate.

fig6: Suggested strain values; A: peak systolic strain (reservoir function), B: peak early diastolic strain (conduit function), C: peak late diastolic strain, D: peak negative diastolic strain, E: time to peak systolic strain, F: early peak systolic strain rate, G: late peak systolic strain rate, H: total systolic strain rate, I: peak negative early diastolic strain rate, and J: peak positive late diastolic strain rate.

Mentions: Strain imaging [115] is the most promising technology for the direct evaluation of LA function [116]. This imaging technique offers many opportunities to measure several quantitative parameters but unfortunately lacks clear standards and validation (Figure 6). Strain imaging begins with the establishment of the onset of time-point markers for analysis (QRS, atrial wave, or aortic closure) and ends with standardized online/offline atrial analyzing software tools from different vendors, which are lacking.
