A patient with a history of lung adenocarcinoma was admitted because of palpitation. Transthoracic echo-cardiogram revealed a mass (74×42 mm) in the right ventricle. Computed tomography showed a tumor lesion in the right ventricular cavity but no other distant metastasis. Coronary angiography revealed well-developed small branches to the tumor. After right heart catheterization, a pathological analysis of a tumor biopsy demonstrated adenocarcinoma. We diagnosed the patient with right ventricular metastasis of lung cancer. With large cardiac metastasis, a tumor biopsy with a right heart catheter may help obtain a pathological diagnosis and also serve as a re-biopsy to confirm the gene mutation status.
