超声心动图评价经导管冠状动脉瘘封堵治疗疗效

目的 探讨超声心动图评价冠状动脉瘘(coronary artery fistula,CAF)经导管封堵治疗疗效的价值.方法 回顾性分析17例CAF患者封堵术前及术后随访的超声心动图资料,观察CAF受累冠状动脉、瘘口的位置和大小等,经导管封堵术后封堵器的位置形态、有无残余分流、房室大小变化等.结果 术前超声心动图检查17例均为单支冠状动脉病变,瘘口大小2～14 mm,平均(6.4±3.5)mm.17例均封堵成功,术后1～4 d超声心动图检查分流消失.随访观察(11.7±7.9)个月,封堵器位置形态正常,无并发症发生,左心室大小恢复正常.结论 CAF经导管封堵治疗是一种微创、安全、疗效确切的方法 ,超声心动图是术前初步筛选及术后随访的主要方法 .

Abstract：

Objective To investigate the efficacy of transcatheter closure of coronary artery fistula (CAF) by transthoracic echocardiography(TTE) and the role of TTE in this therapy. Methods CAF were occluded with transcatheter closure techniques in 17 patients. TTE was performed before and after the treatments. The key points were retrospectively analyzed including: the sites of CAF, the position and diameter of CAF,the shape and position of the devices after the intervention,the residual shunt,and cardiac chamber size. Results Before the therapy,TTE made definite diagnosis of CAF. All patients had lesions in single coronary artery, and the diameter of CAF was 2-14 (6.4 ± 3.5)mm. All patients underwent transcatheter closure successfully. TTE revealed the shunts disappear 1-4 days after the occlusion. During a follow-up period of 1- 29 (11.7± 7.9)months,no residual shunts, no complications, and normal size of thecardiac chambers were recognized by TTE. Conclusions The transcatheter closure of CAF has emerged as a less invasive, safe and effective strategy. Echocardiography has important role in primary screening of patients and the follow-up after the treatments.
