The coronary artery fistulas are rare congenital anomalies with a very low incidence. These can be symptomatic or asymptomatic because the hemodynamic consequences of the fistula vary and depend on the shunt dimensions. Discordant opinions instead are present in the literature for the defect closing in asymptomatic patients. Here, we describe a patient affected by a coronary right fistula canalized in a small accessory right atrial chamber. During follow-up, we observed a progressive dilatation of the right coronary artery (maximum diameter 10.3 mm) with hemodynamic overload of the right sections.
冠状动脉瘘是一种罕见的先天性异常，发病率极低。这些瘘管可能有症状或无症状，因为瘘管的血流动力学后果各不相同，取决于分流的大小。然而，对于无症状患者的缺损闭合，文献中存在不同意见。在此，我们描述一名患有右冠状动脉瘘的患者，该瘘管通向一个小的右心房附属腔室。在随访期间，我们观察到右冠状动脉逐渐扩张（最大直径10.3毫米），右心段出现血流动力学过载。
