Valve advancement was achieved by putting pericardial patch on the incised area along the valve ring of the posterior leaflet. In follow up study, systolic murmur decreased or disappeared, CTR improved markedly. Functional capacity, 82% of total cases had vety good result, 10.7% was fair, 3.6% was poor and death occured in 3.6% in second to 6th postoperative year.
Aortic débridement was performed such manner as slicing thickened and shrinked valvular edge after enough commissurotomy. Decrease in heart murmur and pressure gradient between LV and aorta were resulted. No case which showed enhanced regurgitation after débridement was experienced.
In annuloplasty to tricusped regurgitation Key's method had been applied previously, but DeVega's method covered almost all recent cases. Comparative study between two methods showed, residual regurgitation in 28% of Key's method and in 10% of DeVega's and reccurence of regurgitation due to the rupture of shortened portion in two cases of Key's and none of DeVega's.
