A Novel Case of Immunocompetent Cytomegalovirus enteritis after Cardiac Surgery

Background: Cytomegalovirus enteritis (CMV) post coronary-bypass grafting has never been reported in an immunocompetent patient not on steroids. Moreover, there are no cases in the literature where in CMV enteritis led to small bowel ischemia. Case: An immunocompetent patient presented with NSTEMI, triple-vessel disease and severe left ventricular dysfunction. He underwent urgent CABG. He developed multiple complications including gastrointestinal bleeding, acute abdomen and dialysis-resistant lactate acidosis. He underwent laparotomy and resection of perforated small bowel. Results: Histology revealed CMV enteritis. Conclusions: CMV enteritis must be considered and actively sought in immunocompetent patients who develop GI complications post CABG.
