Abstract Background Acute mesenteric ischemia (AMI) usually presents with abrupt and severe abdominal pain associated with nausea and vomiting. This case is notable due to the occurrence of AMI secondary to acute systolic heart failure caused by new onset complete heart block. Case Presentation A 65-year-old male presented with sudden onset epigastric pain. ECG showed complete AV block and acute ischemia, and a subsequent CTA revealed complete occlusion of the mid superior mesenteric artery. His emergent left heart catheterization showed non-occlusive coronary artery disease. The patient underwent emergent laparotomy and SMA thrombectomy. Postoperative complications included worsening congestive heart failure and persistent bradycardia, requiring a permanent pacemaker. The patient was discharged to a skilled nursing facility in stable condition. Conclusions This case highlights the diagnostic challenges of AMI in the setting of acute heart failure and new onset AV block mimicking acute cardiac events and emphasizes the importance of a multidisciplinary approach in managing such complex cases.
