Intracardiac masses traditionally require surgical excision, often reserved for symptomatic or large tumors.
Many patients with incidentally discovered intracardiac masses undergo prolonged surveillance due to the risks associated with surgery.
Existing management strategies for benign intracardiac tumors often involve a delay in treatment or invasive surgical intervention.
