A Case of Takotsubo Cardiomyopathy in a Patient With Coronary Artery Fistula.

Takotsubo cardiomyopathy (TTC) is also known as stress-induced cardiomyopathy and mimics acute coronary syndrome in the setting of non-obstructive coronary artery disease. It is associated with reversible left ventricular apical, mid, and/or basal wall motion abnormalities. A coronary artery fistula (CAF) is a connection between one or more of the coronary arteries and the cardiac chamber or great vessel. We present a case of an elderly woman who presented with chest pain and was found to have non-obstructive coronary artery disease with wall motion abnormality pattern consistent with TTC and multiple CAF involving the left circumflex coronary artery and pulmonary artery. This case highlights a rare association between two uncommon entities.
