The authors report the case of a 57 years old man who was admitted for angina unresponsive to medical treatment. Coronary angiography revealed significant atherosclerotic lesions in the right coronary artery and also revealed multiple left coronaro-ventricular fistulae, hence the interest of this case. The fistulae were filiform and originated in the circumflex and posterior interventricular arteries. Coronaro-cardiac fistulae are rare, but this type of left-sided coronaro-ventricular fistula is exceptional. The patient was asymptomatic following surgical correction of the atheromatous lesions of the right coronary artery.
