Obstruction of right ventricular outflow tract by extended cardiac metastasis from esophageal cancer.
We report a patient in whom there was right ventricular outflow tract obstruction by extended metastasis from esophageal cancer. A 65-year-old man was admitted to the hospital for evaluation of recent onset of weight loss and heart murmur. Esophagogram and endoscopy showed a 10-cm, ulcerative, infiltrative esophageal cancer. This esophageal cancer was histologically proven to be a squamous cell carcinoma. To assess the cardiac metastasis, echocardiography, magnetic resonance imaging, coronary angiography, and endomyocardial biopsy were performed. The magnetic resonance imaging, echocardiography, and right ventriculography revealed a 7-cm lobulated mass extending to the right ventricular outflow tract, right ventricle, septum, and anterior wall of the left ventricle. Interestingly, the feeding vessels of the tumor were identified by echocardiography and coronary angiography. Histologically, the cardiac tumor was proven to be have the same pathologic findings as esophageal cancer, compatible with carcinomatous metastasis.
