Coronary artery fistulas are rare congenital anomalies that usually drain into one of the cardiac chambers or veins. The current patient was found to have a distinctly unusual anatomic picture, with a fifth cardiac chamber appearing at the cardiac apex. This proved to be the drainage site for a large coronary artery fistula originating in the left anterior descending coronary artery. The anatomic relations and blood flow patterns were demonstrated with transthoracic and transesophageal echocardiography.
冠状动脉瘘是一种罕见的先天性异常，通常引流至心脏腔室或静脉之一。该患者被发现具有明显异常的解剖结构，心脏尖部出现了第五个心腔。事实证明，这是一个起源于左前降支冠状动脉的大型冠状动脉瘘的引流部位。经胸和经食管超声心动图显示了解剖关系和血流模式。
