RESUMEN
Austin Flint murmur is a mid-diastolic rumbling audible in subjects with severe aortic regurgitation. Several theories have been raised to explain mechanistically the nature of this particular phenomenon. We briefly review severe aortic regurgitation under the light of contemporary echocardiography in an illustrative case.

A 51 year-old man was admitted to the coronary care unit due an episode of retroestenal pain with ischaemic alterations in electrocardiogram. It was made the diagnosis of unstable angina. Cinecoronariography showed dilated coronary arteries without obstructions and multiples coronary fistulas draining into left ventricular cavity. Transesophagic echocardiogram with microbubbles injection into coronary arteries showed an important coronary steal phenomena. It is discussed the diagnosis and the treatment. This is one of the rare cases of coronary fistulas draining into the left ventricular cavity and the first one with alterations in the rest ECG.
