title: Synovial sarcoma of the heart.
abstract: A young male presented with dyspnoea and was found to have a diastolic murmur at the left lower sternal edge. Transthoracic and transoesophageal echocardiograms found a large mass attached to the tricuspid valve, which was projecting into the right atrium and the right ventricle. The mass was causing significant obstruction of the right ventricular inflow. Emergency surgery had to be performed because the patient developed severe vomiting (of unknown cause) leading to haemodynamic compromise. This condition was not responding to fluid resuscitation as there was obstruction to right ventricular inflow. Intraoperatively the mass was removed and the tricuspid valve was repaired. The histological and immunohistochemical examination of the excised tissue confirmed the rare diagnosis of synovial sarcoma of the heart.Postsurgical imaging showed no metastases. The patient received postoperative radio therapy and chemotherapy. The tumour recurred after 6 months and the patient succumbed to his illness and expired.
