[Regional and general left-ventricular functions after reconstructive operations and prosthesis of the mitral valve].
The authors used an original method to study the general and regional function of the left ventricle of the heart in patients in the late-term periods after complicated reconstructive operations and mitral valve prosthetics. In patients of the second group increased volumes of the heart were maintained, diminished left ventricular ejection fraction and marked disorders of function in the basal segments were revealed which the authors believe to be caused by excision of the chordo-papillary++ apparatus of the mitral valve and firm fixation of the fibrous ring by the cuff of the prosthesis. These disorders were not encountered in patients who underwent reconstructive interventions which in the presence of the appropriate indications should be the operations of choice because they facilitate fuller restoration of left ventricular function in the late-term periods after surgery.
