Enteropericardial fistulae constitute a condition with a very low prevalence and a high morbidity and mortality rate. In this case report, we discuss an 80-year-old male patient who presented to emergency services for massive rectal bleeding and signs of hypovolemic shock. Abdominal arteriography and upper gastrointestinal endoscopy were negative for bleeding. Findings indicative of fistula between the left ventricle and the transverse colon were described in computed tomography angiogram and the diagnosis was confirmed endoscopically. The patient was stabilized and the bleeding was self-limited.
