Abstract:
Objective To compare the mid- and long-term results of tricuspid valve (TV) repair with or without an annuloplasty ring. Methods Two hundred seventy-seven patients underwent TV repair at our division (Sep. 2001 to Sep. 2008) ,of which 203 had, predominantly, a De Vega or Kay procedure (non-ring group) and 74had an annuloplasty with an artificial ring (ring group). TV pathology mainly was functional (secondary) and several with rheumatic leaflets involvement. Concomitant procedures consisted of mitral valve surgery in all patients,aortic valve surgery in 81 ,and coronary bypass in 19. Clinical and echocardiographic data followed for 1.5 to 3.5years were obtained. Results Postoperationally,the mid-term(1.5 years) follow-up was 100% completed and the long-term follow-up for 3. 5 years was 89. 9%. The recurrence of TV regurgitation (TR) of moderate and lower degree was not significantly different(χ2 = 1.3128, P= 0.26) in the 1.5 years follow-up between the two group,whereas the recurrence of TR of moderate to severity degree was significantly less in the ring group (χ2 =5. 8159,P =0.023).In the long term follow up,the TR in the ring group (25%) was significantly lower than that of 15% in the non-ring group (χ2 = 4. 9328, P = 0.036) . There are higher proportion of patients developing to moderate TR in the non ring group(34%) than in the ring group (10%) (χ2 =7. 9120,P =0.005). The TR developed fast in the ring group,increasing from 18% at 1.5 years follow up to 10% at 3.5 years follow up (χ2 = 2. 1327, P = 0.016),whereas it was relatively stable in the non-ring group,with 7% at 1.5 year follow up and 10% at 3.5 year follow up. Conclusions Placement of an annuloplasty ring in patients undergoing TV repair could remarkably improved the mid and long terum outcome. In clinic practice, we should be more positive to the functional TR and prefer to the procedure with annuloplasty ring.
