Abstract: 目的 应用超声应变显像技术(SI)评价房间隔缺损(ASD)封堵术前、术后心脏功能的变化.方法 选取接受Amplataer封堵器治疗的继发孔型ASD病人50例,分别于ASD封堵术前3 d、术后1周、术后3个月,应用SI在心尖四腔切面测量各房室腔大小、肺动脉收缩压(PASP),右室侧壁三尖瓣环处、右室侧壁中部、室间隔二尖瓣环处、室间隔中部、左室侧壁二尖瓣环处以及左室侧壁中部收缩期峰值应变(Ss).选择健康志愿者50例作为对照组.结果 与对照组比较,ASD组右心房(RA)横径、右心室(RV)横径、PASP增大,差异有显著性(t=2.23~2.87,P<0.05);与术前比较,术后1周RA横径、 RV横径、 PASP显著减小,术后3个月RA横径、 RV横径、PASP进一步减小,差异有显著性(F=7.58~13.46,q=3.50~3.98,P<0.05).与对照组比较,ASD组术前右室壁和室间隔、左室侧壁二尖瓣环处Ss显著增大,差异有显著性(t=2.04~2.97,P<0.05).与封堵术前比较,术后1周右室侧壁、室间隔中部Ss均显著降低(F=8.57~14.66,q=3.67~4.90,P<0.05),术后3个月右室侧壁、室间隔和左室壁Ss均显著降低(q=3.46~3.86,P<0.05);与封堵术后1周比较,术后3个月右室侧壁中部Ss显著降低(F=14.59,q=3.46,P<0.05).结论 SI可准确、定量评价房间隔缺损封堵术前、术后心脏功能的变化,评价封堵术的治疗效果.
