[Early results of mitral valve surgery]

The authors submit a retrospective group of 245 patients operated in the course of 6 years at the Second Surgical Clinic of Cardiovascular Surgery of the General Faculty Hospital and First Medical Faculty Charles University on account of mitral valve disease. The early results of mitral valve prostheses are comparable or in some combined operations better than reported in world statistics. In the etiology the authors found a relative decrease of rheumatic defects and higher incidence of ischaemic affections. The general mortality in mitral valve prostheses was 7.1%, combined operations incl. acute ones being predominant. In mitral plastic operations the authors lost 4 patients, i.e. 19%. In all instances acute combined operations were involved and the result is consistent with the predicted mortality according to the Merged Cardiac Registry. The mean hospitalization period was 7.52 days. A postoperative QIM was recorded in one patient, i.e. in 0.46%, revision after mediastinitis also in one patient (0.41%) and revision after haemorrhage in 14 patients, i.e. in 5.7%. Neurological complications were recorded in 10 patients i.e. 4%. The work emphasizes the trend of improving results in this important area of cardiosurgery and indicates further possibilities and ways of development in the treatment of mitral valve diseases.
