Abdominal Emergency After Subcutaneous ICD Implantation

We describe a previously unreported and potentially fatal complication of colonic perforation following the implantation of a subcutaneous implantable cardioverter-defibrillator in a young patient with nonischemic cardiomyopathy. We discuss the importance of technique and postprocedural evaluation for subdiaphragmatic complications. This description emphasizes presenting complaints, early recognition, and management strategies. (Level of Difficulty: Beginner.).
