Inflammatory bowel disease (IBD) is a debilitating chronic disorder that is classified into Crohn's disease, ulcerative colitis, and unspecified which are marked by recurrent gastrointestinal inflammatory episodes. Anti-tumor necrosis agents, especially infliximab, are considered the cornerstone in disease management. However, rare but serious adverse effects related to infliximab have been reported. Limited studies reported cardiac adverse effects as a result of using infliximab in IBD especially in the pediatric age group. Here, we report a case of an 11-year-old boy known to have Crohn's disease, who was on a regular infusion of infliximab at a monthly basis which developed dilated cardiomyopathy with severe depression of myocardial function.
