目的 利用组织多普勒超声评价阵发性心房颤动(房颤)患者环肺静脉左房线性消融术后左房功能的动态变化.方法 阵发性房颤患者108例,CARTO系统下行环肺静脉左房线性消融术,术前48 h及术后48 h、1个月、3个月、6个月分别行组织多普勒及常规超声心动图检查.结果 106例阵发性房颤患者成功施行环肺静脉左房线性消融术.与术前相比,左房前后径和左房容积减小,但术后48 h、1个月差异无统计学意义(P＞0.05),术后3个月和6个月差异有统计学意义(P＜0.05);左室舒张末内径、左室收缩末内径、左室射血分数差异无统计学意义(P＞0.05);二尖瓣舒张早期峰速差异无统计学意义(P＞0.05),二尖瓣舒张晚期峰速术后48 h较术前降低(P＜0.05),术后1个月、3个月、6个月逐渐增高,3个月时恢复到术前水平.与术前相比,二尖瓣环左室侧壁收缩期峰速、舒张早期峰速差异无统计学意义(P＞0.05),舒张晚期峰速术后48 h较术前降低(P＜0.05),术后1个月、3个月、6个月逐渐增高,1个月时恢复到术前水平.结论 环肺静脉左房线性消融术后左房内径和容积减小;环肺静脉左房线性消融术后可出现左房主动收缩功能降低(左房顿抑),经过一段时间可自行恢复.
目的 利用組織多普勒超聲評價陣髮性心房顫動(房顫)患者環肺靜脈左房線性消融術後左房功能的動態變化.方法 陣髮性房顫患者108例,CARTO繫統下行環肺靜脈左房線性消融術,術前48 h及術後48 h、1箇月、3箇月、6箇月分彆行組織多普勒及常規超聲心動圖檢查.結果 106例陣髮性房顫患者成功施行環肺靜脈左房線性消融術.與術前相比,左房前後徑和左房容積減小,但術後48 h、1箇月差異無統計學意義(P＞0.05),術後3箇月和6箇月差異有統計學意義(P＜0.05);左室舒張末內徑、左室收縮末內徑、左室射血分數差異無統計學意義(P＞0.05);二尖瓣舒張早期峰速差異無統計學意義(P＞0.05),二尖瓣舒張晚期峰速術後48 h較術前降低(P＜0.05),術後1箇月、3箇月、6箇月逐漸增高,3箇月時恢複到術前水平.與術前相比,二尖瓣環左室側壁收縮期峰速、舒張早期峰速差異無統計學意義(P＞0.05),舒張晚期峰速術後48 h較術前降低(P＜0.05),術後1箇月、3箇月、6箇月逐漸增高,1箇月時恢複到術前水平.結論 環肺靜脈左房線性消融術後左房內徑和容積減小;環肺靜脈左房線性消融術後可齣現左房主動收縮功能降低(左房頓抑),經過一段時間可自行恢複.

Objective To evaluate left atrial function serial change after circumferential pulmonary vein ablation(CPVA)for paroxysmal atrial fibrillation using tissue Doppler echocardiography.Methods One hundred and eight patients with paroxysmal atrial fibrillation underwent CPVA guided by CARTO.Tissue Doppler imaging and conventional echocardiography were underwent 48 h before CPVA,48 h,1 month,3 month and 6 month after CPVA.Results One hundred and six patients with paroxysmal atrial fibrillation finished CPVA successfully.Compared tO 48 h pre-CPVA,left atrial diameter and volume decreased 48 h,1 month,3 month,6 month after CPVA,significant change were found at 3 month,6 month after CPVA(P＜0.05).Left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD).left ventricular ejection fraction(LVEF),mitral flow E revealed no significant change(P＞0.05).Mitral flow A decreased significantly 48 h after CPVA(P＜0.05),restored significantly after 3 month.Tissue Doppler parameter S'and E'revealed no significant change(P＞0.05)through the period,A'decreased significantly 48 h after CPVA(P＜0.05),restored significantlv after 1 month.Conclusions Left atrial diameter and volume decreased after CPVA.Left atrial active contraction function decreased shortly after CPVA(LA stunning),and restored progressively.
