Infective Endocarditis due to Esophageal Squamous Cell Carcinoma Invasion of the Left Atrium: A Case Report.

Esophageal cancer is often diagnosed at an advanced stage and with distant metastases. While cardiac metastases from solid tumors have been reported in 0.2%-6.5% of postmortem cases, solitary cardiac metastases remain exceedingly rare.
