Primary benign cardiac tumours: Long-term results

Abstract

OBJECTIVES: Primary heart tumours are rare lesions with variegated histological types. We reviewed our 35 years experience with a significant number of primary benign cardiac tumour cases. METHODS: The patient database at University of Bologna was searched to identify patients with primary cardiac tumours between 1974 and 2009. Benign tumours were classified as myxomas and non-myxomas. Ninety-four were myxomas (mean age of 59.1 ± 15.6), and 13 were benign non-myxomas tumours (mean age of 39.7 ± 24.9; P = 0.0001). Complete resection of the masses was performed in all cases except in one. RESULTS: In-hospital mortality was 3% in the myxoma group and 8% in the non-myxoma group. The mean follow-up was 15.1 and 7.4 years for the myxoma and non-myxoma groups, respectively. The long-term survival of discharged patients was 68 ± 7% for the myxoma group and 100% for the non-myxoma group at 20 years, respectively. Recurrence of a tumour occurred only in the myxoma group (four cases) after 1, 3, 5 and 8 years, respectively. Twenty patients had an extracardiac tumour that was diagnosed before operation in 12 (11 in the myxoma group) and during the follow-up in 8 patients (only in the myxoma group). CONCLUSIONS: Primary cardiac tumours can be surgically treated with good short- and long-term results. Mortality and morbidity are mainly due to the status of preoperative patients'. An accurate follow-up is mandatory in order to detect the recurrence of a cardiac tumour such as to exclude the presence or the development of extracardiac tumours that we found frequently associated with the myxoma. © The Author 2011.
