[Hemolytic anemia following surgical repair of mitral valve insufficiency in children].

The description of hemolytic anemia after mitral valve repair has been infrequent. The present paper presents this complication, discussing its diagnosis and surgical aspects, such as the association with the use of teflon felt for posterior annuloplasty. This complication happened in two children at our institution, one treated medically with supplementation of folic acid and ferrous sulfate and another requiring surgery for replacement of the teflon felt using a piece of heterologous pericardium for a new annuloplasty and leaflet advancement.
