Successful surgery of neuroendocrine carcinoma infiltrating right
ventricle and pulmonary artery
We present the clinical case of a 60-year-old woman complained of
dyspnea on exertion. Echocardiogram showed a giant mass in right
ventricle (RV) with obstruction to the outflow tract. Thorax CT
confirmed a mass of >60 mm infiltrating RV and causing
severe stenosis in pulmonary artery, with severe pericardial effusion.
Cardiac surgery was performed for tumor resection and pulmonary root
replacement with a biological valved conduit. Histological analysis
diagnosed a poorly differentiated large-cell neuroendocrine carcinoma.
The patient had no immediate postoperative complications and has
completed radiotherapy at 6-month follow-up.
