Intravenous leiomyomatosis is a rare gynecologic disease that can be complicated with intracardiac involvement. All reported cases with cardiac extension involved the right cardiac chambers. Intracardiac leiomyoma may present with dyspnea, chest pain, palpitations, lower extremity swelling, or syncope. This is a unique case of a 40-year-old asymptomatic woman with incidental finding of a cardiac murmur. Echocardiography showed an echodensity in all cardiac chambers. Urgent cardiac surgery revealed an intracardiac leiomyoma, extending from the inferior vena cava and involving all four cardiac chambers and the aortic root.
