Echocardiographic detection and long-term outcome of coronary artery-left ventricle fistula after septal myectomy in hypertrophic obstructive cardiomyopathy.

We describe a 51-year-old woman with an acquired coronary fistula to the left ventricle. Reports in the literature about acquired coronary fistulas to the left ventricle are scarce. In this patient, the fistula developed after septal myectomy for hypertrophic obstructive cardiomyopathy. Transesophageal echo-cardiography may be the preferred method to diagnose and evaluate these fistulas. Moreover, in contrast to fistulas to the right ventricle, conservative management carried a good prognosis in this patient.
