Surgical excision of a giant calcified amorphous tumour of the right ventricle and right pulmonary artery

A cardiac calcified amorphous tumour (CCAT) is a rare non-neoplastic intracavitary mass with unknown causes. We describe a 32-year old male presenting with progressive dyspnoea, cough and oedemas. The transthoracic echocardiography and contrast-enhanced angio-computed tomography demonstrated a 4 × 10 cm calcified mass into the right ventricle and total occlusion of the right pulmonary artery. The patient underwent successful total removal of the mass through a transverse right ventriculotomy, and right pulmonary embolectomy. Histopathological examination of mass confirmed the diagnosis of a CCAT. The postoperative course was uneventful. To our knowledge, this is the first reported case with a confirmed diagnosis of CCAT at two different locations and the third undergoing a combined approach aiming at total mass excision.
