title: [Surgical treatment of Fallot's tetralogy with hyperplasia or agenesis of the conal septum].
abstract: BACKGROUND
  The clinical evolution, anatomosurgical aspects, and postoperative evolution of a specific group of Fallot's tetralogy with hipoplasic or agenesic of the conal septum (representing a 7% of our Fallot's tetralogy cases) is presented.
  
  
  METHODS
  A total of 41 patients surgically corrected in our Service between February 1973 and December 1995 has been retrospectively studied. Ages ranged between 13 months and 13 year. Clinically all cases developed moderate or severe hypoxemia. In 43.9% of cases it was necessary to perform a palliative surgery at an age between 15 days and 4 years.
  
  
  RESULTS
  There was no hypoxemics spells. In the ECG we have found a QS in the aVR in 40% of cases. There was 7 deaths (17% of mortality rate). Four cases required reoperation. The clinical evolution, ECG, EKO, and hemodynamics findings are commented.
  
  
  CONCLUSIONS
  In this type of Fallot's tetralogy, specifically in those cases with a pulmonary artery ring of normal size, it is necessary to have a good preoperative diagnoses in order to perform a longitudinal ventriculotomy with right ventricular outflow tract enlargement. Also, it is important to be meticulous with the stitches in the closure of the ventricular septal defect with a patch in order to avoid the potential lesion of the aortic valve.
