[Left ventricular pseudoaneurysm with a fistula to right ventricle following previous repair of septal defect after acute myocardial infarction].

A case of left ventricular pseudoaneurysm with a fistula to right ventricle is presented. It appeared following the repair of a ventricular septal defect after acute myocardial infarction. The left ventricular pseudoaneurysm is associated, in most cases, with acute myocardial infarction. However, we should not forget surgery as aetiology of this pathology. The most frequent post-surgery pseudoaneurysms appear after aneurysmectomy and after mitral valve replacement. They tend to develop fistulas which differ from post acute myocardial infarction pseudoaneurysms. Few cases have been described following the repair of septal defect and none of them complicated with a fistula to right ventricle, as in our case.
