Acquired coronary-to-left ventricle fistula: evidence by myocardial contrast echocardiography.
The case report subject is a patient with an old anteroseptal myocardial infarction and postinfarction angina who developed, over the years, a small left coronary-to-left ventricle fistula. The first coronary angiogram, performed 4 months after the infarction, was negative for coronary fistula. The diagnosis was made 3 years later, at repeat cardiac catheterization with myocardial contrast echocardiography. Left and right coronary injections of 0.2 cc of sonicated 5% human albumin microbubbles generated a bright cloud of contrast entering the left ventricular cavity at the level of the distal third of the interventricular septum. Conversely, cineangiography failed to show on-line the fistulous communication that was evident only after careful cineangiographic reviewing. This case demonstrates the high efficacy of myocardial contrast echocardiography in identifying very small coronary fistulae.
