Surgical experience with cardiac tumours at the General Hospital, Kuala Lumpur.

Fifteen patients underwent surgery for cardiac tumours in General Hospital Kuala Lumpur between October 1984 and June 1989. Twelve of the patients had cardiac myxomas and underwent excision under cardiopulmonary bypass. Two patients had sarcoma, of which one was excised. The other was inoperable. Another patient had a metastalic malignant melanoma which was inoperable. Of the patients 10 were female and five male. Their ages ranged from 16 to 60 years. All were symptomatic and the commonest mode of presentation was exertional dyspnoea and palpitations. Two presented with cerebral embolisation. The three patients with malignant tumours had constitutional symptoms at the time of surgery. All patients had echocardiography pre-operatively to confirm the diagnosis of cardiac tumour. Only one patient underwent preoperative cardiac catheterisation and angiography. The surgical approach in all patients was through a median sternotomy and all except one were operated under cardiopulmonary bypass. There was no intraoperative embolisation. There was one perioperative death. Fourteen patients were followed up for periods ranging from one to 44 months. Three patients with malignant cardiac tumours died. One had recurrence of myxoma 21 months after the initial surgery. We conclude that excision of cardiac myxomas carry a very small risk following which patients have good prognosis. Malignant tumours carry a bad prognosis. From our experience, we conclude that echocardiography is an extremely accurate tool in the diagnosis of cardiac tumours.
