Abstract BACKGROUND Left atrial (LA) mechanics is impaired in mitral valve disease, but it is not clear whether reservoir, conduit or contractile functions are differentially impaired in stenosis (MS) or regurgitation (MR). We aimed to study LA mechanics in patients with moderate MR or moderate MS and identify discriminators of disease. METHODS We conducted a prospective, observational study of 100 patients with isolated moderate MR and 100 patients with moderate MS. LA mechanics with speckle tracking echocardiography (STE) assessed LA reservoir (LA ɛsys and SRs), conduit(LAɛe, SRe), and contractile (LAɛa, SRa) functions. Left ventricle (LV) functional parameters were assessed as well, including LV ejection fraction (LVEF), LV end-diastolic diameter (LVDD) and LV global longitudinal strain (LV-GLS). RESULTS The mean age was 67 ± 14 years and 75% were female. Mean left ventricular ejection fraction (LVEF), LV end-diastolic diameter (LVDD), LV global longitudinal strain (LV-GLS) and systolic pulmonary artery pressure (sPAP) did not differ between MR and MS (table 1).LA indexed volume (LAVi) and LA strain did not vary between MR and MS, but strain rate did. SRs and SRe had better values in MR, whereas SRa had worse values in MR (table 1). SRe (<-0.7%) had the superior discriminative power for MR, with an area under the curve of 0.85, sensitivity of 76% and specificity of 85%. CONCLUSIONS LA strain rate phases were the only parameters that varied between MR and MS. Contractile phase strain rate was more impaired in MR and conduit phase strain rate in MS. This highly specific data reflect the earlier hemodynamic changes occurring in LA in the setting of mitral valve disease. mMR mMS P value LVEF (±SD,%) 57.4 ± 6.4 59.6 ± 4.6 0.145 LV-GLS (±SD, %) -17.7 ± 4.5 -17.1 ± 3.5 0.587 sPAP (±SD, mmHg) 30.3 ± 10.5 32.4 ± 8.3 0.387 LAVi (± SD, ml/m2) 46.3 ± 6.4 48.2 ± 7.4 0.281 LAɛs (± SD, %) 15.8 ± 7.3 13.3 ± 9 0.062 LAɛe (± SD, %) 8.4 ± 4.7 7.1 ± 5.4 0.074 LAɛa (± SD, %) 6.3 ± 4.8 7.4 ± 4.5 0.081 LA SRs (± SD, %) 0.8 ± 0.4 0.6 ± 0.3 0.004 LA SRe (± SD, %) -0.9 ± 0.5 -0.5 ± 0.3 <0.001 LA SRa (± SD, %) -0.5 ± 0.4 -0.8 ± 0.5 0.007
