A Rare Case of Transient Mesenteric Ischemia After Atrial Fibrillation With Rapid Ventricular Response Rate

TL;DR

A patient on anticoagulation therapy developed transient mesenteric ischemia due to atrial fibrillation with a rapid heart rate, highlighting the importance of prompt diagnosis and treatment.

Contribution

This case report highlights a rare clinical scenario where transient mesenteric ischemia occurred without surgical intervention.

Findings

Transient mesenteric ischemia occurred despite chronic anticoagulation therapy.

Prompt recognition and heart rate control prevented the need for surgery.

Atrial fibrillation with rapid ventricular response can lead to embolic mesenteric ischemia.

Abstract

Mesenteric ischemia is an urgent event and requires prompt recognition and treatment, in order to reduce the risk of mortality. It results from the sudden onset of small intestinal hypoperfusion, from a reduction or cessation of arterial perfusion, which can occur from an embolic obstruction at the superior mesenteric artery. We present a case of transient mesenteric ischemia from an episode of atrial fibrillation with a rapid ventricular response rate. Despite being on chronic anticoagulation therapy, the patient developed transient mesenteric ischemia from an embolic clot. The patient's heart rate was controlled and no surgical intervention was required, a rare finding; however, it is very important to recognize and treat promptly.
