| 摘 要： | 目的 应用应变率成像(SRI)技术对风湿性二尖瓣狭窄患者换瓣前后心肌收缩功能进行测量,并评价其判断二尖瓣换瓣术预后的价值.方法 42例风湿性二尖瓣狭窄患者按术后恢复情况分为A、B两组:A组30例为恢复良好组,B组12例为恢复较差组;健康对照组26例.术前及术后常规超声心动图检测二尖瓣瓣口面积、左心房和左心室大小、左心室射血分数、左心室短轴缩短率;应用SRI技术测量左心室各壁基底段和中间段收缩期峰值应变率(SRs)参数,比较术前、术后1个月的SRs变化情况.结果 术前A、B两组左心室壁各节段SRs均小于对照组相应节段(P＜0.05);B组各节段SRs均小于A组对应节段(P＜0.05).术后A组左心室壁各节段明显改善(P＜0.05).B组术后左心室壁各节段SRs改善不明显(P＞0.05).结论 SRI技术可定量评价风湿性MS患者心肌收缩功能,对判断手术预后具有一定的临床意义.
