According to unselected autopsy data, primary cardiac tumours are a rare entity. About 80% of the tumours are benign and nearly half of these are myxomas. In clinical practice, when diagnosis of this pathological entity is ascertained, decision for surgical treatment is made in order to prevent thromboembolism and obstruction of the valvular apparatus. Surgical resection including total tumour removal is accompanied by low perioperative mortality. The recidive rate is low in sporadic cases. However, in familial syndrome groups, such as the Swiss-Carney syndrome, the recurrence rate is higher.
