Although primary cardiac tumors are rare, cardiac metastasis
of malignant tumors is not as infrequent as we might suspect.
of transitional cell carcinoma has been previously reported in the right ventricle, left atrium, and pericardium.
Although he had not received treatment for his metastatic melanoma, heart failure due to obstructive cardiac metastasis
is generally a poor prognostic indicator.
of other primary tumours would be 20 to 30 times more frequent.

from a bronchial carcinoid: report of a case presenting with diffuse thickening of the left ventricular wall.
In one reported case, (23) the first and only cardiac manifestation of cardiac metastasis
of lung cancer was irreversible, sustained, ventricular arrhythmia leading to death.
The incidence of cardiac metastasis
has been reported to be 2.3% and 18.3% of autopsied cases of carcinoma.[sup.1,2] It has been reported that 10% of autopsied cases of urothelial carcinoma (UC) exhibited cardiac metastases.[sup.3] However, the metastases are clinically silent in most cases.
We present a case in which the clear identification of the primary tumour and cardiac metastasis
altered the surgical management and avoided a high-risk anaesthetic.
is a rare known entity in such cases.
(21) Cardiac metastasis
is typically associated with widely disseminated disease.
by malignant tumors is uncommon, with a prevalence ranging from 0.4% to 20.6%.(1)(2)(3) Primary tumors that most commonly metastasize to the heart are lung, breast, melanoma, and sarcoma.(1)(2) Gastric cancers uncommonly metastasize to the heart, with a reported prevalence of approximately 2.8%.(1) Metastasis to the heart can occur by hematologic dissemination (embolism of tumor cells), by lymphatic invasion, or by direct extension, as often occurs with a lung cancer invading the heart.
