Inflammatory myofibroblastic tumor of the right ventricle causing tricuspid valve regurgitation.
Cardiac inflammatory myofibroblastic tumor is a rare lesion consisting of inflammatory cells and myofibroblastic spindle cells. We describe a case of inflammatory myofibroblastic tumor that involved the right ventricle, thereby causing tricuspid valve regurgitation in an 18-year-old man who presented with a fever of unknown origin and of 1 month's duration. With the patient on cardiopulmonary bypass, we excised the lesion and replaced the tricuspid valve without serious intraoperative or postoperative sequelae. The patient had a favorable outcome.
