Non-myxomatous cardiac tumours: twenty-year experience.

Eighty-eight patients underwent surgery for various cardiac tumours from January 1978 to June 1998 at our Institute. Seventy-seven tumours were myxomas, 10 were non-myxomatous and one was secondary cardiac tumour. Case records of the patients with non-myxomatous primary cardiac tumours and one secondary tumour were reviewed. Six of these primary tumours were benign and four, malignant. Age of the patients ranged from 26 days to 47 years. Among patients (3 children, 8 adults) with non-myxomatous primary cardiac tumours, dyspnoea on exertion was the commonest symptom and was the cause of presentation in seven out of 11 patients. Of the eight adults, six were in New York Heart Association functional class II/III and two in class IV. Echocardiographic diagnosis was possible in all the patients. Complete excision of the tumour was possible in all benign and two of the four malignant tumours. Incomplete resection was done in the secondary tumour. Of the six benign tumours, three were rhabdomyomas and one each of fibroma, haemangioma and lipoma. The malignant tumours were one each of fibrosarcoma, angiosarcoma, unclassified sarcoma and malignant mesothelioma. The secondary tumour was a malignant thymoma. Follow-up ranged from 1 to 10 years (mean 7.2 years). Of the patients with benign tumours, four out of six are alive; one patient died on the first post-operative day and one lost to follow-up. Two of the four patients with malignant cardiac tumours died, one was lost to follow-up and one is alive two years after surgery. The patient with secondary malignant thymoma to the superior vena cava was lost to follow-up three months after an uneventful recovery from surgery.
