Acute Coronary Syndrome in a Puerperal Patient with Coronary Artery Ectasia due to a Coronary Artery Fistula.

Coronary artery fistulas are rare and the feeding artery is ectatic and tortuous. It is not well-known whether coronary artery ectasia (CAE) is a risk factor of acute coronary syndrome (ACS) in the puerperal periods. A 40-year-old woman with a coronary artery fistula and an ectatic right coronary artery (RCA) had delivered twins. A month later, she had chest pain and coronary angiography revealed thrombogenesis in the RCA. She had no risk factors of cardiovascular disease or thrombogenesis. We should recognize that CAE is a risk factor for ACS in women in the perinatal and puerperal periods.
