Abstract: 【Abstract】〓Objective〓To evaluate short-and mid-term outcomes of tricuspid suture annuloplasty and tricuspid ring annuloplasty for functional tricuspid regurgitation by echocardiography. Methods〓From January 2008 to June 2013,175 patients underwent tricuspid annuloplasty for functional tricuspid regurgitation. Two kinds of techniques were used: suture annuloplasty in 143 patients (82%), and ring procedure in 32 patients(18%). LVEF、TRA、TRF、RVD、RAD1、RAD2 were measured by echocardiongraphy preoperatively and postoperatively in one month and one year, and then compared between the two approaches. Results〓The degree of TRA, TRF, RAD1, RAD2 decreased significantly after operation in all patients. There was no significant change of LVEF. TRF were significant larger in one year than that in one month after operation(P<0.05). Other patameters had no significant change during the time after operation in suture annuloplasty group (P>0.05). There were no significant change of the degree of all patameters in one year than those in one month after operation in ring annuloplasty group (P>0.05). Conclusins〓For patients with functional tricuspid regurgitation,the mid-term outcomes were satisfactory by ring annuloplasty. Echocardiography is useful in semi-qualify evaluation of the tricuspid regurgitation pre- and post-operatively.
