Abstract

BACKGROUND: Ross procedure is ideal aortic valve replacement method with several merits of hemodynamic superiority and durability without the need of anticoagulation. Based upon this presumption, we studied its procedure performed in our hospital and tried to get the mid-term results MATERIAL AND METHOD: From Jan 1999 to Oct 2001, 22 patients underwent the Ross procedure. The mean age of experimented (including 17 men and 5 women) was 30.9+/-8.1 (17~44). The diagnosis before the surgery had shown 20 as accompanied with AR and the rest 2 as with ASR. The follow-up period ranged from 0.6 to 40.6 months, mean of 38.9+/-1.6 months, and follow-up rate was 100%. RESULT: There was no operative death and two late deaths, one of whom was cardiac originated and the other, non-cardiac relate The survival rate was 94.1+/-5.7% (40.6 months). Postoperatively there were 2 exploration for bleeding, 3 low cardiac output patients. The pulmonary autograft technique was root replacement in 14 and inclusion technique in 8. Pulmonary homografts were used at the pulmonary position in all cases. There was no patient with significant aortic regurgitation.
CONCLUSION
These showed that the mortality and morbidity of the Ross procedure were acceptable and postoperative AR was not significant. However, further long-term follow-up will be necessary for the improvement of the function of pulmonary autograft and homograft.
