摘要:
目的 应用二维斑点追踪成像技术评价二尖瓣狭窄患者右室心肌纵向应变，探讨该技术在评价此类患者右室收缩功能中的临床应用价值。方法 随机选取我院收治的风湿性心脏病单纯二尖瓣狭窄患者55例，经胸超声心动图测量二尖瓣瓣口面积（MVA）及右室收缩功能指标，包含三尖瓣环收缩期峰值速度（S′）、三尖瓣环收缩期位移（TAPSE）、右室做功指数(RIME)及右室面积变化分数(FAC)，根据三尖瓣反流法估测肺动脉收缩压（PASP）；二维斑点追踪成像（2D-STI）测量右室游离壁纵向收缩期峰值应变(RVLSFW)，并根据RVLSFW值将患者分为两组，RVLSFW<-19％为A组，RVLSFW≥-19%为B组。结果 两组患者MVA、PASP、TAPSE、S′、RIMP、FAC及RVLSFW差异有统计学意义(P<0.05)，其中RVLSFW≥-19％的二尖瓣狭窄患者右室收缩功能减低更为明显(P<0.05)；RVLSFW与PASP、RIMP呈正相关关系(r值分别为0.521、0.511，P值均<0.05)，与MVA、TAPSE、FAC、S′呈负相关关系(r值分别为-0.521、-0.410、-0.435、-0.385，P值均<0.05)。结论 右室心肌纵向应变能够评价二尖瓣狭窄患者右室收缩功能，为临床提供更多可靠信息。
Abstract:
Objective To measure right ventricular longitudinal strain in patients with mitral stenosis (MS) by 2D speckle tracking imaging(2D-STI), and explore the clinical value of this technique in evaluating right ventricular systolic function in these patients. Methods Fifty-five patients with rheumatic mitral stenosis who were treated in our hospital were randomly selected. The mitral valve orifice area (MVA) and right ventricular systolic function index including tricuspid lateral annular systolic velocity (S′), tricuspid annular plane systolic excursion (TAPSE), RV index of myocardial performance (RIME) and right ventricular fractional area change (FAC)were measured by transthoracic echocardiography(TTE), and the pulmonary systolic pressure(PASP) was estimated by the tricuspid regurgitation method； 2D speckle tracking imaging (2D-STI) was used to measure the free-wall right ventricular longitudinal strain (RVLSFW), and the patients were divided into two groups according to the RVLSFW value: group A with RVLSFW<-19%, and group B with RVLSFW≥-19%. Results There were significant differences in MVA, PASP, TAPSE, S′, RIMP, FAC and RVLSFW between the two groups (P<0. 05), and the right ventricular systolic function decreased more significantly in patients with RVLSFW≥-19% mitral stenosis (P<0. 05);RVLSFW was positively correlated with PASP and RIMP (r= 0. 521, 0. 511, P<0. 05), and negatively correlated with MVA, TAPSE, FAC and S′ (r=-0. 521, -0. 410, -0. 435, -0. 385, P<0. 05). Conclusion Right ventricular longitudinal strain can evaluate right ventricular systolic function in patients with mitral stenosis, and provide more reliable information for clinical practice.
