[Neurinoma of the posterior cerebral fossa and mitral valve prolapse. Possible association and study of possible peri-operative consequences on rhythm].
27 patients with an acoustic neurinoma were submitted to a complete cardiological survey oriented towards the detection of mitral valve prolapse (2D echo) and ECG signs of a particular risk of arrhythmia (standard ECG and continuous Holter monitoring). 9 of these 27 patients presented MVP, but none of them presented any serious ventricular arrhythmias. The corrected QT interval was significantly longer in patients without MVP. The frequency of the association of MVP and acoustic neurinoma can not be explained simply by the female predominance of the series and its should be interpreted with reservation in the absence of a control series. The absence of pre-operative arrhythmia does not exclude the potentiating role of MVP in the development of certain cases of unexplained post-operative death.
