Bad heart luck: Myocardial infarction related to iatrogenic coronary cameral fistula in a heart transplant patient

Endomyocardial biopsy (EMB) remains the gold standard method for diagnosis of cardiac allograft rejection. Complications following EMB rarely occur, however, it can lead to coronary cameral fistulae (CCF). We describe the case of a 65-year-old patient admitted for lateral STEMI related to a fistula communicating the distal part of the left anterior descending artery (LAD) with the right ventricle after EMB biopsy, which was incompletely closed with a covered stent.
