Coronary artery fistulae (CAF) are uncommon heart lesions, but they are the most frequent significant hemodynamic congenital coronary anomaly. Transcatheter closure is an alternative treatment and a variety of techniques and devices were reported to use for the closure of congenital coronary fistulae.
We reported a 5-year-10-month-old boy who was diagnosed as CAF at birth. Follow-up transthoracic echocardiography showed persistent CAF and progressed dilatation of the left coronary artery.
Coronary angiography showed torturous coronary vessel and CAF at the distal segment of the left circumflex artery (LCX).
Antegrade approach with Amplatzer Vascular Plug was used due to the retrograde approach failed and showed a good result.
During a 3-year follow-up period, the patient showed no symptoms and demonstrated good exercise ability. Follow-up coronary angiography showed the Amplatzer vascular plug was located at an adequate position without a residual shunt from the CAF, and the diameter of the left coronary artery regressed when compared to previous angiography results.
The antegrade approach is a feasible method for closing CAF if torturous vessels are noted and fistulae occur at the distal portion of the coronary artery. A large randomized study or case series are needed to investigate the comparison of antegrade and retrograde method for the closure of CAF.
冠状动脉瘘(CAF)是一种罕见的心脏病变,但却是最常见的具有显著血流动力学意义的先天性冠状动脉异常。经导管封堵是一种替代治疗方法,已有多种技术和器械被报道用于先天性冠状动脉瘘的封堵。
我们报告了一名5岁10个月大的男孩,他在出生时被诊断为CAF。随访经胸超声心动图显示CAF持续存在,且左冠状动脉扩张进展。
冠状动脉造影显示左旋支动脉(LCX)远端段冠状动脉迂曲且存在CAF。
由于逆行封堵失败,采用了经Amplatzer血管封堵器的顺行封堵方法,效果良好。
在3年的随访期内,患者无症状,运动能力良好。随访冠状动脉造影显示Amplatzer血管封堵器位置合适,CAF无残余分流,与之前的造影结果相比,左冠状动脉直径缩小。
如果冠状动脉迂曲且瘘发生在冠状动脉远端,顺行封堵方法是封堵CAF的一种可行方法。需要进行大型随机研究或病例系列研究来比较顺行和逆行封堵CAF的方法。
