title: [Mechanical circulatory support in pediatrics. Experience at the Dr. Juan P. Garrahan Pediatric Hospital. Argentina].
abstract: BACKGROUND
  Mechanical circulatory support provides oxygen to the tissues in patients with cardiac and/or respiratory reversible disease refractory to conventional treatments.
  
  
  OBJECTIVE
  The aim of this study is to show our initial results of mechanical circulatory support in children with heart disease.
  
  
  METHODS
  Retrospective cohort between March 2006 and March 2012. Demographic data (age, sex, weight, cardiac diagnosis), surgery (technique, pump, aortic cross clamping time) and mechanical circulatory support (type of assistance, indication, duration, complications and outcome) were collected.
  
  
  RESULTS
  Thirty-three patients were supported (1.3% of all surgeries), extracorporeal membrane oxygenation 32 cases and one ventricular assist device. The median age 7.4 months (one day-18 years) and weight 6kg (2.3-75). The most frequent cardiac malformations supported were the transpositions of the great arteries associated with other anomalies and the corrected transpositions (ventricular inversion or double discordance). The most common reason for admission was post-cardiotomy biventricular dysfunction. Twenty-eight patients were supported in the postoperative period, 4 in the preoperative period and in one with myocarditis. Median days of support were 3 days (1-10). The most common complications were infection (21%), bleeding (21%). Elective decannulation was achieved in 94% of cases. Hospital discharge survival: 52%.
  
  
  CONCLUSIONS
  The mechanical circulatory support in our institution is a safe and standard procedure. We have been using it in a small number of cases with a similar survival to that reported internationally. This complex procedure is widely justified because it allows for the recovery of more than half of the patients who otherwise would have died.
