目的：探讨二维斑点追踪技术在继发孔型房间隔缺损(ASD)患者封堵手术前后评价左室短轴应变中的应用。方法连续入选继发孔中央型 ASD 患者30例为病例组，分别于封堵术前、术后2 d 及术后6个月进行超声检查，应用斑点追踪技术测量左室短轴圆周应变及径向应变峰值，并与正常对照组比较。结果①ASD 患者封堵术前各节段的圆周应变峰值均低于对照组(P <0.05)。前间隔、前壁、侧壁、后壁术后2 d 较术前显著增高(P <0.05)，高于对照组(P <0.05)；术后6个月减低至正常水平；下壁、室间隔术后2 d 即增高至正常水平。②ASD 患者术前除后壁外各节段的径向应变峰值均低于对照组(P <0.05)，术后2 d 增高(P <0.05)并接近于对照组；后壁径向应变术前高于对照组(P <0.05)，术后6个月减低(P <0.05)并接近于对照组。③ASD 患者左室整体圆周应变术前低于对照组(P <0.05)，封堵术后2 d 增高(P <0.05)，高于对照组(P <0.05)；术后6个月降低至正常水平。ASD 患者术前左室整体径向应变与对照组差异无统计学意义，封堵术后2 d 增高(P <0.05)，亦高于对照组(P <0.05)，术后6个月恢复正常。结论应用二维斑点追踪技术可以定量评价 ASD 患者封堵术前、后左室各节段及整体圆周应变、径向应变的变化。
目的：探討二維斑點追蹤技術在繼髮孔型房間隔缺損(ASD)患者封堵手術前後評價左室短軸應變中的應用。方法連續入選繼髮孔中央型 ASD 患者30例為病例組，分彆于封堵術前、術後2 d 及術後6箇月進行超聲檢查，應用斑點追蹤技術測量左室短軸圓週應變及徑嚮應變峰值，併與正常對照組比較。結果①ASD 患者封堵術前各節段的圓週應變峰值均低于對照組(P <0.05)。前間隔、前壁、側壁、後壁術後2 d 較術前顯著增高(P <0.05)，高于對照組(P <0.05)；術後6箇月減低至正常水平；下壁、室間隔術後2 d 即增高至正常水平。②ASD 患者術前除後壁外各節段的徑嚮應變峰值均低于對照組(P <0.05)，術後2 d 增高(P <0.05)併接近于對照組；後壁徑嚮應變術前高于對照組(P <0.05)，術後6箇月減低(P <0.05)併接近于對照組。③ASD 患者左室整體圓週應變術前低于對照組(P <0.05)，封堵術後2 d 增高(P <0.05)，高于對照組(P <0.05)；術後6箇月降低至正常水平。ASD 患者術前左室整體徑嚮應變與對照組差異無統計學意義，封堵術後2 d 增高(P <0.05)，亦高于對照組(P <0.05)，術後6箇月恢複正常。結論應用二維斑點追蹤技術可以定量評價 ASD 患者封堵術前、後左室各節段及整體圓週應變、徑嚮應變的變化。

Objective To explore the short axial strain of left ventricle in patients with atrial septal defect(ASD)before and after the transcatheter closure by using two-dimensional speckle tracking imaging (2D-STI).Methods A total of 30 patients with ASD underwent echocardiography before and after the transcatheter closure.The procedure was performed to obtain the peak of circumferential strain(Sc)and radial stain(Sr)of left ventricle by 2D-STI.Thirty healthy volunteers were enrolled as controls.Results ①Compared with the control group,regional myocardial Sc of ASD group decreased(P <0.05).Sc of anterior septum (AS),anterior wall (AW),laterior wall (LW)and posterior wall (PW)increased (P <0.05)at 2-days after the transcatheter closure and those parameters were higher than control group.At the six-months after the transcatheter closure,those parameters reduced to the normal level (P <0.05).Sc of inferior wall (IW)and mid-posterior septum (MP-Sept)increased to the normal level at 2-days after the closure surgery (P <0.05).②Compared with control group,regional myocardial Sr of ASD group decreased(P <0.05 ) except PW,two-days after the transcatheter closure these parameters increased to the normal level.Sr of PW in ASD group increased compared with control group(P <0.05),and there were no statistical changes at 2-days after the transcatheter closure.Sr of PW in ASD decreased (P <0.05 )to normal level until 6-months after the transcatheter closure.③ Global circumferential strain (GCS)of left ventricular in ASD group were lower than control group (P <0.05 ).At two-days after undergoing transcatheter closure the GCS increased (P <0.05)and those parameters were higher than control group (P <0.05).Six-months after the transcatheter closure those parameters reduced to the normal level (P < 0.05 ).There were no statistical differences of left ventricular global radial strain (GRS)between control group and ASD group. However,the GRS of ASD group increased (P < 0.05 )and those parameters were higher than control group (P <0.05)after 2-days undergoing the transcatheter closure.At six-months after the transcatheter closure those parameters were reduced to normal level (P <0.05 ).Conclusions 2D-STI can quantitative evaluate left ventricular circumferential strain and radial strain in patients with ASD before and after the transcatheter closure.
