title: [Ebstein anomaly and pregnancy].
abstract: BACKGROUND
  The Ebstein's anomaly is a congenital malformation of the tricuspid valve and of the right ventricle that usually is associated with interauricular communication, foramen oval, and arrhythmias of Wolff-Parkinson-White syndrome type.
  
  
  OBJECTIVE
  To analyze the association between Ebstein's anomaly and pregnancy.
  
  
  METHODS
  A prospective study was made in five pregnant women's with Ebstein's anomaly without surgery. We analyzed the clinical history, physical examination, electrocardiogram, x-ray of thorax, Doppler color heart ultrasound, and fetal valoration by means of pelvic ecosonogram and cardiotocographic registry, and routinely prenatal paraclinic tests.
  
  
  RESULTS
  We observed severe expansion of the ventricle and 3rd degree index of atrialization in two patients. In two pregnancies there were interatrial communication (patients with cyanosis) and in three was detected severe tricuspid insufficiency. The average of gestacional age was of 36.4 +/- 1.8 weeks. Two of the five pregnancies has preterm birth. Only one childbirth was short weight to gestational age. The rest stayed within percentile 10. There were no obits or neonatal deaths, either congenital abnormality by Doppler heart ultrasound.
  
  
  CONCLUSIONS
  The pregnancy is well tolerated in patients with Ebstein's anomaly; nevertheless, participation of multidisciplinary team is recommended to establish the treatment.
