[Mechanical mitral valve prosthesis dysfunction in pregnant women. Report of 2 cases].
We present two cases of pregnant women associated with mechanical mitral valve prostheses dysfunction, treated between October 1998 and September 2000, in congestive heart failure, functional class III, without fetal distress. Emergency surgery consisted in cesarean procedure immediately followed for mitral prostheses removal and implantation of new mechanical heart valve prostheses was realized in both patients. In each case a single live infant was obtained with good Apgar evaluation. Both patients had successful surgical procedures. In both patients were found thrombi in the mechanical heart valves. Actually patients and their children have good evolution, without any problem.
