[Myxoma of the right ventricle in monozygotic twins: surgical ablation]

Monozygotic twins aged 23 underwent surgery, at an interval of 4 months from each other, for a myxomatous tumour of the right ventricle which had been completely asymptomatic until then. The authors present the clinical, electrocardiographic and angiographic findings, together with details of the operation and of the histological findings. They recall how rare a site this is, and summarise some of the observations which have been made on familial myxomas.
