Abstract
BACKGROUND: This study simultaneously reports bilateral atrial tumor masses including the concurrent occurrence of metastatic carcinoma, consistent with metastatic breast carcinoma, on the main cardiac myxoma mass in the left atrium (LA) and metastatic carcinoma consistent with metastatic breast carcinoma for the right atrial (RA) mass.CASE REPORT: These masses were observed in a 79-year-old female patient who had received her pacemaker 6 months ago due to electrical conduction disease. However, no tumor/mass was found in her echocardiogram at the time of the pacemaker reception and mild chest pain and dyspnea were the only signs of her huge masses. Bilateral interseptal atrial cardiac masses protruded to the LA and RA were observed in both atrial chambers in echocardiography, and she underwent the surgical resection of masses.CONCLUSION: The findings of the current study represented a novel condition for a patient. More precisely, the patient had two different huge cardiac masses, and at the same time, the metastasis of breast cancer was reported on the other cardiac tumor/myxoma as well. In addition, metastatic carcinoma should be suspected in patients with cardiac myxoma mass consistent with heart block. The simultaneous presence of multiple masses inside the heart is not always evidence of myxoma, rather can be a metastatic lesion.
