title: [Ross procedure in treatment of aortic disease: clinical experience of 15 cases].
abstract: OBJECTIVE
  To summarize the clinical experience of Ross procedure in treatment of aorta valve diseases.
  
  
  METHODS
  The clinical data of 15 patients with aorta valve diseases, 12 men and 3 women, aged 30 +/- 14, including 13 cases of congenital aorta valve disease, 1 case of senile degenerative aortic valve disease, and 1 case of subacte bacterial endocarditis complicated by aortic stenosis (AS), with the heart function (NYHA) of class II in 11 cases and class III in 4 cases, underwent Ross procedure from October 1994 to September 2002 in Anzhen Hospital. Before operation, ultrasound cardiography showed moderate to severe AS and/or aortic insufficiency (AI) with an average aortic valve annulus diameter (AVD) of 2.4 +/- 0.4 cm and normal pulmonary valve. Operation was performed on all patients under cardiopulmonary bypass and moderate hypothermia. The operation procedure was as follows: (1) to take off the auto-pulmonary artery valve; (2) to remove the dysfunctional aortic valve and auto-transplant the pulmonary valve on the aortic root; and (3) to put a pulmonary homograft so as to re-establish on the right ventricular outflow tract.
  
  
  RESULTS
  The perieoperative mortality is 0. After the operation, the mean pressure gradient of aortic valve was in the normal limitation (7.23 +/- 0.14 mm Hg), the left ventricular diastolic diameter decreased significantly (P < 0.001), the left ventricular ejection fraction was 0.48 +/- 0.22, and the heart function (NYHA) was at the classes I - II in all the patients. All cases received follow-up of 1 - 9 years, their heart function was all in Class I, and the function of their aortic and pulmonary valves remained well.
  
  
  CONCLUSIONS
  Ross procedure is a kind of effective alterative operation in treating patients with aortic valve disease.
