Discussion
Clinically, tumor metastasis to the heart is rare and often ignored. Patients with cardiac masses with a history of a tumor should considered. TTE is usually the first examination to identify intracardiac groups. However, cardiac imaging techniques, such as PET-CT, can accurately determine the nature of cardiac masses and the invasion of pericardial structures, which is a fundamental step in guiding clinical surgical and non-operative treatment strategies.
There is no doubt about whether metastatic heart tumors should remove. Surgery is essential for treating cardiac tumors[2] and the first choice for all cardiac tumors [3]. As reported in the literature[4,5], cardiac surgery is very effective for benign cardiac tumors and most malignant tumors (primary or secondary). It can solve the potentially and rapidly life-threatening situations associated with heart disease. Besides, cardiac surgery and cardiopulmonary bypass have no adverse effects on the survival of patients with malignant tumors [6] and can achieve low early mortality and excellent survival rate[7].
However, the patient did not receive formal medical treatment, so cervical squamous cell carcinoma metastasized to the left cervical lymph node and recurrence in the valvula tricuspidalis. The treatment of metastatic cardiac tumors is not a single mode of medicine but a combination of surgery, medical treatment, and advanced diagnosis, which may significantly impact the survival of these patients[8,9].
