Coronary artery fistulas are rare and are most often diagnosed by echocardiography or by cine-angiocardiography. However, the computed tomography angiography (CTA) of coronary arteries has been gaining ground. The incidence of this disease is very low, with a more frequent occurrence of fistulas originating in the right coronary artery. There is a higher incidence of coronary artery fistulas to right heart chambers, with coronary artery fistulas to the left ventricle (LV) being rare. Treatment can be surgical or percutaneous. This report describes a case of coronary fistula to left ventricle diagnosed by CT angiography of coronary arteries in a hypertensive and asymptomatic 46-year-old male, who was tested positive for ischemia in an exercise test. The CT angiography ruled out coronary obstructive disease, but it revealed a coronary fistula to the left ventricular cavity.
冠状动脉瘘非常罕见，通常通过超声心动图或电影血管造影来诊断。然而，冠状动脉计算机断层血管造影（CTA）的应用越来越广泛。这种疾病的发病率非常低，更常见的是起源于右冠状动脉的瘘。冠状动脉瘘更常通向右心腔，而通向左心室（LV）的瘘非常罕见。治疗方法可以是手术或经皮。本报告描述了一例冠状动脉瘘至左心室的病例，该病例通过冠状动脉 CT 血管造影在一位高血压且无症状的 46 岁男性中得到诊断，该男性在运动试验中呈缺血阳性。CT 血管造影排除了冠状动脉阻塞性疾病，但发现了一条通向左心室腔的冠状动脉瘘。
