We present 3 cases of coronary artery-right ventricular fistulae diagnosed on yearly check-ups on 160 cardiac transplant patients between September 1982 and January 1995. The fistula was communicating with the ventricular branch of the right coronary artery, the septal branch of the left anterior descending artery and the distal right coronary artery in the three cases being reported. Histological examination of the endomyocardial biopsy specimen showed the presence of small calibre arteries which were not seen in other cases. Although endomyocardial biopsy carries a risk of less than 0.5 percent, the possibility of causing coronary artery-ventricular fistula should be added to the list of the complications of this procedure. The shunt caused by these fistulae is small and has no hemodynamic significance and usually does not warrant any treatment.
我们报告了1982年9月至1995年1月期间，在对160名心脏移植患者进行年度体检时诊断出的3例冠状动脉-右心室瘘病例。在报告的这3例病例中，瘘管分别与右冠状动脉的心室支、左前降支的间隔支以及右冠状动脉远端相通。心内膜活检标本的组织学检查显示存在小口径动脉，这在其他病例中未见。尽管心内膜活检的风险低于0.5%，但冠状动脉-心室瘘的发生可能性应被列入该操作并发症的清单中。这些瘘管引起的分流较小，无血流动力学意义，通常无需任何治疗。
