[Special features of anesthesia during surgery for acquired heart valve defects].

The authors describe some special features as regards anesthesia with large opioid doses in patients operated on account of acquired valvular disease. They emphasize in particular the importance of adequate knowledge of pathophysiological changes associated with the damage of different orifices and their interpretation in the anaesthesiological procedure which is the basis of its success. In the conclusion the authors describe basic haemodynamic changes in combined simultaneous affection of several valves.
