BACKGROUND
Mitral annulus motion (MAM) obtained by echocardiography can be used in the assessment of left ventricular systolic function (LVSF). However, it has been shown that the amplitude of MAM is decreased in patients with left ventricular wall thickness (LVWT) greater than 14 mm.
OBJECTIVE
To study if the amplitude of MAM can be used in the assessment of LVSF in patients with LVWT in the upper limit of normal to mild hypertrophy (12 mm to 14 mm).
METHODS
Eighteen consecutive patients with LVWT of 12 mm to 14 mm were compared to 18 age- and sex-matched patients with LVWT less than 12 mm.
RESULTS
There was no significant difference between the amplitude of MAM in the two groups.
CONCLUSIONS
MAM can be used in the assessment of LVSF in patients with LVWT in the upper limit of normal to mild hypertrophy and be related to reference values.
背景
通过超声心动图获得的二尖瓣环运动（MAM）可用于评估左心室收缩功能（LVSF）。然而，已有研究表明，左心室壁厚度（LVWT）大于14mm的患者MAM幅度降低。
目的
研究MAM幅度是否可用于评估LVWT处于正常上限至轻度肥厚（12mm至14mm）患者的LVSF。
方法
将18例连续的LVWT为12mm至14mm的患者与18例年龄和性别匹配、LVWT小于12mm的患者进行比较。
结果
两组的MAM幅度无显著差异。
结论
MAM可用于评估LVWT处于正常上限至轻度肥厚患者的LVSF，且与参考值相关。
