One hundred eight patients (Feb. '86, through Jan. '96)underwent 53 mitral(MVR), 20 aortic(AVR), 35double(DVR) valve replacement with SJM prosthesis. There were 55 males and 53 females whose mean age was 36.3±10.4 years. We used 143 valves in
mitral(88), aortic(54), and tricuspid(1) sites. The size and number of valves were 31mm(32), 33mm(23), 29mm(20), 27mm(10), 25mm(2), and 35mm(1) in mitral site; 23mm(21), 21mm(18), 19(7), 25mm(5), 27mm(2), and 33mm(1)in aortic site; and 31mm(1) in
tricuspid site. Preoperative NYHA functional classes were II(14), III(73) and IV(21), and which were improved into I(89) and II(16) postoperatively.
Early postoperative complications occurred in 15cases(13.9%) in which LOS was the most common one(5 cases; 4.6%). Early hospital death occurred in 3 cases(2.8%) due to LOS(1) and sudden cardiac arrest(2). The cummulative total follow-up period
was
437.6
pt-yr with a mean of 4.1±2.9 years. There were 5 events of valve related complications(2 TE, l paravalvular leak, l PVE) with the occurrence rate as 1.14%/pt-yr. Reoperation was performed in 2 cases and there were 2 cases of valve related death
due to
one PVE and one paravalvular Leak. The complication free rate was 91.4±3.4% at 10 years. Actuarial survival rate was 93.6±3.1% at 10 years.
