[Ruptures of the posterior wall of the left ventricle after mitral valve replacement: surgical repair and prevention].

We report two cases of type III rupture of the left ventricle posterior wall, situated midway between the mitral annulus and the posterior papillary muscle and occurring in immediate continuations of a mitral valvular replacement. The first case has occurred at the moment of the canulas removal in a 28 years old patient operated for mitral stenosis. The tear was repaired with horizontal mattress sutures through felt strips on the external surface of the heart.

[Cerebral infarction, pseudolupic syndrome and myxoma of the left atrium].

Left atrial myxomas are a rare stroke etiology (0.4%). They frequently present general symptoms such as fever, weight loss and an inflammatory syndrome, but the pseudolupic syndrome with cutaneous features and vasomotor symptoms is rarely described.
