先天性冠状动静脉瘘(CAVF)于1865年首次报告,为一罕见的心脏疾病。在无症状者或有充血性心衰者或缺血征象者常表现为不典型的局限性连续性杂音。该症可用心导管和血管造影术来确诊。磁共振(NMR)成像是一种新的用来发现许多先天性心脏畸形的非侵入性技术。作者介绍了2例经血管造影证实为左冠状动脉右心室瘘,并用NMR成像技术进行研究。病例1,6岁男孩。1月龄时心脏有持续性杂音和心脏扩大,当时心导管发现有冠状动脉左前降支(LAD)到右室的CAVF,肺循环量/体循环量为3.5∶1,肺动脉压正常。开始以地戈辛治疗。患儿失
Congenital coronary arteriovenous fistula (CAVF) was first reported in 1865 as a rare heart disease. In asymptomatic or congestive heart failure or ischemic signs often showed atypical localized continuous murmur. The disease can be confirmed by cardiac catheterization and angiography. Magnetic resonance (NMR) imaging is a new noninvasive technique used to discover many congenital heart defects. The authors present two cases of right ventricular fistula confirmed by angiography as left coronary artery and studied by NMR imaging. Case 1,6 year old boy. At 1 month of age, the heart had persistent murmur and enlarged heart. At that time, the CAVF of the left anterior descending coronary artery (LAD) to the right ventricle was found in the cardiac catheter. The volume of pulmonary circulation / systemic circulation was 3.5: 1 and the pulmonary pressure was normal. Began to digoxin treatment. Children lost
