From July 1974 to January 1986, 50 patients underwent conservative repair for rheumatic aortic valvular disease at our institution. Eleven were male and 39 female, with an average age of 39.5 years (range 17- 57). The aortic lesion was associated in all cases with a predominant mitral lesion. Twenty-five also had tricuspid disease which was surgically treated in 17. Twenty-six had aortic regurgitation and 24, a mixed lesion. The surgical techniques used were: (1) commissurotomy, (2) annuloplasty, (3) cusp free edge unfolding and (4) supra-aortic crest enhancement. Two patients had one cusp extended with pericardium. There were 3 hospital deaths (6%). Six patients were lost to follow-up at different periods. Maximum follow-up was 12.58 years with a mean of 7.78 years per patient. Twelve required reoperation with 3 deaths. Three reoperations were due to failure of the mitral bioprosthesis without reoperation on the aortic valve. Of the remaining 9 patients who had aortic and mitral dysfunction, 4 had severe aortic insufficiency. The actuarial freedom from reoperation at 13 years was 75% and the overall actuarial survival was 86%. It is concluded that these surgical techniques can be applied successfully in moderate rheumatic aortic valve disease accompanying a predominant mitral lesion. This is particularly relevant when a mitral reconstruction has been performed.
