title: [Aortic valve replacement with pulmonary autograft (Ross procedure). Initial experience].
abstract: OBJECTIVE
  Report the initial surgical experience with four cases utilizing a pulmonary autograft for aortic valve replacement.
  
  
  METHODS
  Four patients, all males, white, age between 23 and 46 years having aortic valve disease were submitted to aortic valve replacement with a pulmonary autograft using the root replacement technique. Right ventricular outflow tracts were reconstructed with antibiotic sterilized pulmonary or aortic homografts. All patients had control bidimensional eco-doppler (ECO) and hemodynamic study to evaluate the function of the implanted auto and homografts.
  
  
  RESULTS
  All patients had an excellent post-operative recovery, without the necessity of inotropic drugs. All presented in normal sinus rhythm. Post-operative ECO and hemodynamic studies revealed excellent function of the implanted autografts, without gradients in three and with a 15mmHg mean residual gradient in one case. There was no regurgitation in three cases and only trace aortic insufficiency in one. The right sided homografts also showed good function, with no gradient in two cases and mean systolic gradient of 6 and 8mmHg in the other two.
  
  
  CONCLUSIONS
  The pulmonary autograft procedure should be implemented definitely in our country.
