BACKGROUND A coronary cameral fistula is a rare connection between a coronary artery and a cardiac chamber or vein bypassing the cardiac capillary bed system. Most of these fistulae are congenital and solitary, although they can be acquired and multiple. CASES PRESENTATION Case 1: A 10-year-old black South African boy presented with a long-standing history of fatigue; he had a heart murmur, and a bounding pulse and wide pulse pressure. An echocardiogram demonstrated a large coronary cameral fistula involving his left coronary artery and his left ventricle. This was also confirmed on ascending aortogram. Surgical ligation was done and his symptoms improved afterward, but a small residual fistula remained. Case 2: A 7-year-old black South African boy had decreased effort tolerance and a heart murmur on the mid-sternal border. He had cardiomegaly on chest roentgenogram and a dilated left coronary artery origin on echocardiogram. An ascending aortogram confirmed a large left coronary cameral fistula draining to the left ventricle. Case 3: A 28-year-old black South African woman with decreased effort tolerance and chest pain on exertion had a continuous murmur over the lower sternal border. Echocardiography demonstrated a dilated right coronary artery with a fistulous connection to her right ventricle. An ascending aortogram demonstrated a tortuous coronary cameral fistula arising from her right coronary artery to her right ventricle. All three patients were successfully treated percutaneously using the Amplatzer vascular plug type II device. CONCLUSION The availability of numerous vascular closure devices has made transcatheter occlusion the treatment of choice for the majority of coronary cameral fistulae, rather than the traditional surgical ligation.

巨大先天性冠状动脉瘘的经导管闭塞：病例系列。

背景技术冠状动脉瘘是冠状动脉与心室或静脉之间绕过心脏毛细血管床系统的罕见连接。大多数瘘管是先天性的、孤立的，但也可以是后天性的、多发的。病例介绍 病例 1：一名 10 岁南非黑人男孩，因长期疲劳病史就诊；他有心脏杂音，脉搏跳动，脉压宽。超声心动图显示，他的左冠状动脉和左心室有一个大的冠状动脉瘘。升主动脉造影也证实了这一点。进行了手术结扎，随后症状有所改善，但仍有一个小的残余瘘管。病例2：南非7岁黑人男孩，体力耐力下降，胸骨中缘有心脏杂音。胸部X线检查显示他有心脏扩大，超声心动图显示左冠状动脉起源扩张。升主动脉造影证实有一个大的左冠状动脉瘘，引流至左心室。病例3：一名28岁的南非黑人女性，患有体力耐受力下降、用力时胸痛、胸骨下缘持续性杂音。超声心动图显示右冠状动脉扩张，并与右心室有瘘管连接。升主动脉造影显示从她的右冠状动脉到右心室的曲折的冠状动脉瘘。所有三名患者均使用 Amplatzer II 型血管塞装置成功进行经皮治疗。结论 多种血管闭合装置的出现使得经导管闭塞术成为大多数冠状动脉瘘的治疗选择，而不是传统的手术结扎。
