Posttraumatic aortico-right ventricular fistula: a case study.

Posttraumatic formation of either aortico-ventricular or coronary arterio-ventricular fistulas are rare, albeit well-documented events. A case is presented involving crush injury to the chest complicated by an acute inferior wall myocardial infarction and later associated with an aortico-right ventricular fistula. Progressive right ventricular dilatation dictated subsequent surgical repair in this case, although similar fistulas without dilatation may safely be observed.
