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.

Grade one shows a reduced E/A ratio mitral inflow, measured by PW-Doppler, and a reduced E′/A′ ratio, measured by PW-TDI. Grade 2 represents “pseudonormalization,” and Grade 3 represents restrictive physiology [35, 73].

fig2: Grade one shows a reduced E/A ratio mitral inflow, measured by PW-Doppler, and a reduced E′/A′ ratio, measured by PW-TDI. Grade 2 represents “pseudonormalization,” and Grade 3 represents restrictive physiology [35, 73].

Mentions: Oh et al. [35] postulated 3 grades of diastolic dysfunction (Figure 2). These authors illustrated a schematic diagram of the “sucking” of blood into the left ventricle from the left atrium by good relaxation or the “pushing” of blood into the left ventricle by an increased filling pressure in patients with diastolic dysfunction.
