Abstract

|
Fourty-five cases of operation were performed for the correction of tricuspid regurgitation(TR) in Pusan National University Hospital between 1982 and 1991.
The mean age of the patients was 32.6 years and female was dominant(M:F=1:2.2). Isolated tricuspid regurgitation was rare and 43 patients underwent concomitant other valvular operation including mitral valve replcement. Functional cause was in 39
cases
and organic lesions were found in 6 cases.
Operative methods were Kay annuloplasty(29), De Vega annuloplasty(12), and tricuspid valve replacement(4). Ring annuloplasty was not performed. Operative mortality rate was 11.1%(5/45) and late mortality rate was 6.7%(2/30). The tricuspid valve
surgery
itself was not a serious risk factor for hospital death and no heart block or thrombosis was complicated.
By echocardiogram early(within 30 days) and late(mean:4.9 years) changes of postoperative TR were evaluated. De Vega annuloplasty seemed to bring better late result than Kay annuloplasty(p<0.05). In four patients with late severe TR, previously
replaced
tissue valve degeneration(2), pulmonary hypertension(1) and rheumatic TR (1) were the possible causes. This experience suggests that De Vega annuloplasty can be a reliable method in the majority of patients with moderate-to-severe functional TR.
