Coronary artery fistula with associated Takotsubo cardiomyopathy: a case report

摘要

BackgroundCoronary artery fistula, first described by Krause in 1865, is an abnormal communication between the coronary artery and one of the four chambers of the heart or one of the great vessels. The communications are often congenital but may also be acquired from trauma or invasive cardiovascular procedures. Half of the cases present with angina pectoris whereas the remaining half are incidentally detected on echocardiogram or angiogram performed for an unrelated reason.Takotsubo cardiomyopathy or stress-induced cardiomyopathy is characterized by transient left ventricular dysfunction with minimal elevation of cardiac biomarkers in the absence of underlying coronary artery disease. Almost 90% of reported patients are postmenopausal women with a history of recent emotional or physical stress.
