This case highlights the challenges in treating children with intracardiac thrombosis.
We describe a teenager who developed an unsuspected de novo intracardiac thrombus. She was treated initially medically and surgically, but required subsequent surgery to treat a life-threatening recurrence. This case demonstrates an unusual presentation, as well as imaging, diagnostic, and therapeutic dilemmas. More significantly, it emphasizes the importance of a multidisciplinary approach for successful treatment of intracardiac thrombus.
