Insights
A rare, fatal complication of colonic perforation can occur after subcutaneous implantable cardioverter-defibrillator (ICD) placement. Early recognition and proper technique are crucial for managing this serious subdiaphragmatic event in patients with cardiomyopathy.
Area of Science:
- Cardiology
- Gastroenterology
- Medical Devices
Background:
- Subcutaneous implantable cardioverter-defibrillators (ICDs) are increasingly used for managing arrhythmias.
- Nonischemic cardiomyopathy is a common indication for ICD implantation.
- Subdiaphragmatic complications following ICD implantation are rare but can be severe.
Abstract:
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.).
