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 le ft ventricle. Reports in the Literature about acquired coronary fistulas to the left ventricle are scarce. In this patient, the fistula developed afte r septal myectomy for hypertrophic obstructive cardiomyopathy, Transesophag eal echocardiography may be the preferred method to diagnose and evaluate t hese fistulas. Moreover, in contrast to fistulas to the right ventricle, co nservative management carried a good prognosis in this patient.
