Congenital coronary artery fistula is an uncommon anomaly. Transcatheter coil embolization or Amplatzer vascular plug device closure of fistula is often done in symptomatic patients with safe accessibility to the feeding coronary artery. Embolization of Amplatzer vascular plug device is rare. We report an 11-year-old male child who presented to us with increasing shortness of breath for 7 years. He had a history of Amplatzer vascular plug device closure of right coronary-cameral fistula 8 years back. Echocardiography demonstrated a dilated aneurysmal right coronary artery with turbulent jet entering into the right ventricle (RV) and device embolized into the left pulmonary artery (LPA). Cardiac catheterization eventually confirmed the diagnosis. Surgical closure of fistula and retrieval of device was done using cardiopulmonary bypass. Intraoperatively transesophageal echocardiogram helped in localizing fistula opening in the RV below the anterior leaflet of tricuspid valve, continuous monitoring to prevent further distal embolization of the device during surgical handling, and assessment of completeness of repair of the fistula and LPA following retrieval of the device.
先天性冠状动脉瘘是一种罕见的异常情况。对于有症状且能安全进入供血冠状动脉的患者,常采用经导管线圈栓塞或使用Amplatzer血管封堵器关闭瘘管。使用Amplatzer血管封堵器进行栓塞的情况较为罕见。我们报告一名11岁男性儿童,他因气短加重7年前来就诊。他8年前有使用Amplatzer血管封堵器关闭右冠状动脉 - 心腔瘘的病史。超声心动图显示右冠状动脉呈动脉瘤样扩张,有湍流进入右心室,封堵器栓塞至左肺动脉。心脏导管检查最终确诊。通过体外循环进行瘘管的手术关闭和封堵器取出。术中经食管超声心动图有助于定位三尖瓣前叶下方右心室的瘘口开口,持续监测以防止手术操作过程中封堵器进一步向远端栓塞,并在封堵器取出后评估瘘管和左肺动脉修复的完整性。
