INTRODUCTION: Heart primary tumors may be maligns or benigns, whereas the secondary tumors always are of metastatic origin. The 75% of primary tumors are benigns and of a endocavitary localization, most are of myxoma type mainly in adult people. METHODS: From a total of 2925 patients were operated on using extracorporeal circulation between January, 1986 and January, 2006 in "Hermanos Ameijeiras" Clinical Surgical Hospital, thirty clinical records were selected from patients histologically diagnosed with cardiac myxoma. For results analysis we applied incidence estimates. In variables percentages, means and standard deviation were used. RESULTS: A total of 19 patients were females and 11 were males with an age range between 15 and 66 years (mean, 44 years). Clinical elements from the symptomatology point of view were varied and with a predominance of palpitations and dyspnea in 83% and 73% of patients, respectively. Appearance symptoms interval was from 1 month to 92 months (mean, 15 months). Echocardiogram confirmed the 100% of diagnosis in patients. The more frequent myxomas localization was the left atrium (80% of cases). All patients underwent tumor exeresis and its implantation basis. Mortality observed was of 6,6%. CONCLUSIONS: Incidence of this disease was of 1,2% of all patients operated on in that period. Female-male sex ratio was of 2:1. Echocardiogram is the cornerstone of the positive diagnosis of cardiac myxomas. The mortality of this series was within the documented ranges in international medical literature.
