[Right coronary-cardiac fistulae. Anatomic and clinical study, course and therapy. Apropos of 3 new cases].

Three cases of coronary-cardiac fistulae diagnosed in the Cardiologic Unit of the Dijon University Hospital are reported. With reference to these cases current knowledge on this rare condition is reviewed. Symptomatology is variable, with sometimes only a systolic and diastolic murmur on the sternal border, usually with good functional tolerance. A thorough investigation, including left angiography, ascertains diagnosis and shows the exact nature of the lesions. Surgery is almost always advocated as it often ensures good results and avoids delayed complications, which are mainly heart failure by coronary insufficiency, and infectious endocarditis.
