[Myxoma of the right ventricle. Apropos of 2 cases]

Two cases of primary cardiac tumour are reported. The first was that of a 16 year old girl investigated after the detection of a systolic murmur on routine examination. The clinical signs suggested a diagnosis of pulmonary stenosis. The second case was that of a 36 year old man admitted to hospital for right ventricular failure. Echocardiography revealed right ventricular tumours in both cases and also indicated their size, form, mobility and site of implantation. The outcome of the first case, a fibromyxoma, was favourable with no detectable recurrence after one year. In the second case, the patient unfortunately died of cardiogenic shock in the immediate preoperative period. These two cases emphasise the value of echocardiography in the diagnosis of isolated right ventricular tumours, especially considering the difficulty of clinical diagnosis and the risks of angiocardiography.
