[Left coronaro-ventricular fistula after myocardial infarction. Apropos of a case].
Coronary artery-cardiac fistulae are uncommon and usually congenital abnormalities. The majority of these fistulae communicate with the right heart chambers. Acquired coronary-left heart fistulae are very rare: secondary to trauma, cardiac surgery, angioplasty or endomyocardial biopsy. Fistulae secondary to myocardial infarction are rare but have been described. The authors report the case of a man with anterior wall infarction treated by fibrinolysis and by angioplasty of the left anterior descending artery (LAD) 48 hours later. This dilatation was complicated by repeated occlusion but a good result was obtained after in situ and then systemic fibrinolysis. Control coronary angiography after angioplasty performed 6 months later showed the presence of micro-fistulae between the distal part of the LAD, the left diagonal entry and the left ventricular chamber which were not present on the coronary angiogram before the angioplasty. The fistulae appeared to be secondary to a localised infarct which occurred after distal thrombosis of the LAD during angioplasty.
