摘要：
We studied left atrial (LA) function in severe rheumatic mitral stenosis (MS) patients using twodimensional speckle tracking echocardiography (STE). Eighty patients with isolated severe MS in sinus rhythm and 40 controls underwent comprehensive echocardiography including STE derived LA strain [reservoir strain (LAS(r)), conduit strain (LAS(cd)) and contractile strain (LAS(ct))]. The mean MVA was 0.93 +/- 0.21 cm(2). The mean values of LASr (14.73 +/- 8.59%), LAS(cd) (-7.61 +/- 4.47%) and LAS(ct) (-7.16 +/- 5.15%) in patients were significantly lower (p < 0.001) vs. controls 44.11 +/- 10.44%,-32.45 +/- 7.63%,-11.85 +/- 6.77% respectively and showed decreasing trend with increasing MS severity and higher NYHA class. In conclusion, LA dysfunction is prevalent in severe MS irrespective of NYHA functional class. (C) 2021 Cardiological Society of India. Published by Elsevier B.V.
