Abstract：

Objective To analyze whether association of edge to edge valve repair to artificial ring annuloplasty would result in better results in patients with severe tricuspid regurgitation (TR).Methods From April,2001 to May,2010,41 patients underwent tricuspid valve repair to treat severe TR were studied.Twenty-one patients were done artificial ring annuloplasty alone (group R) and twenty patients were done artificial ring annuloplasty associated with edge to edge valve repair ( group E).All the patients received echocardiography before surgery,before discharge and in mid and long-term follow-up.The ratio between TR jet area (TRA) and right atrial area (RAA) was used to quantitatively evaluate the seriousness of TR.Movement of tricuspid valve leaflets,tricuspid valve orifice area,pulmonary artery pressure ( PAP),left ventricular ejection fraction ( LVEF) were obserbed to evaluate heart function.Results At discharge in group R,no or trivial TR was presented in 7 patients,mild TR in 12 patients and moderate TR in 2 patient.Bad apposition of the free edges of anterior and septal leaflets was observed in paients with mild and moderate TR.While in group E,no or trivial TR was presented in 13 patients and mild TR in 7 patients.The follow-up ranged from 6 months to 100 months[average (54.8 ±26.7) months].In group R,no or trivial TR was present in 5 patients,mild TR in 11 patients,moderate TR in 4 patients and severe in 1 patient.Bad apposition of the free edges of anterior and septal leaflets was observed in paients with mild to severe TR.Redo tricuspid valve repair was done in one patient in group R for recurrent severe TR and the edge-to-edge valve repair was utilized.In group E,no tricuspid stenosis was found.No or trivial TR was presented in 10 patients,mild TR in 9 patients and moderate TR in 1 patient.The ratio of TRA/RAA of group R was significantly higher than that of group E (0.25 ±0.16 vs.0.13±0.10,P < 0.01).Conclusion Association of edge-to-edge valve technique to artificial ring annuloplasty was safe and effective for treatment of severe tricuspid regurgitation due to bad apposition of free edges of tricuspid leaflets and dilatation of tricuspid annulus,.It could decrease the incidence of residual tricuspid regurgitation and prevent the recurrence of severe tricuspid regurgitation.

Association of edge-to-edge repair to De Vega annuloplasty for tricuspid incompetence

BACKGROUND: We aimed to analyze whether association of edge to edge repair to De Vega annuloplasty would result in better results in patients with severe TR. METHODS: Fifty seven patients with TR>/=3 were randomized to undergo modified De Vega alone (group D, 28 patients) or associated with edge to edge repair (group E, 29 patients). All patients had preoperative and two postoperative (early and mid-term) echocardiography. The tricuspid regurgitation, diameter of tricuspid valve annulus, pulmonary artery pressure and right ventricular EF were recorded. RESULTS: Early postoperative echocardiography indicated less residual TR in group E while other parameters were comparable. The mean follow-up period was 28.2+/-5.4 months. Mid-term postoperative mean TR was 1.9+/-0.8 vs. 1.0+0.4 (p=0.0384) indicated less redevelopment of TR in group E. Additionally TVA re-dilatation was found more prominent in group D. One patient in group D underwent operation for recurred TR. CONCLUSION: Our results suggested that association edge-to-edge technique to De Vega annuloplasty has resulted in reduced residual TR and less incidence of recurrence of TR and TVA dilatation.     

A novel approach of tricuspid valve repair: mitralization of tricuspid valve

Open in a separate window OBJECTIVESThis study presents the mid-term results of a novel tricuspid valve (TV) repair strategy defined as ‘mitralization of TV’ (resection and plication of the posterior leaflet, ring implantation, optional leaflet procedures) applied for the correction of tricuspid regurgitation (TR).METHODSBetween 2017 and 2020, a total of 22 patients underwent concomitant TV repair using mitralization of the TV. Fourteen of the patients had functional TR (2 of them had severe tethering), 5 patients had prolapse and 3 patients had rheumatic involvement.RESULTSThere was no in-hospital mortality. Moderate or severe TR was not observed in any patient in echocardiographic evaluations before discharge. The mean follow-up duration was 30.9 + 6.2 months. Moderate-to-severe TR-free survival was 100% in the second year and 94.7% in the third year.CONCLUSIONSMitralization of the TV is a safe and effective treatment modality in terms of its mid-term results. This new technique provides an innovative perspective for the treatment of TR, especially in complex TV pathologies.     

A prosthetic ring annuloplasty with edge-to-edge repair for a treatment of severe tricuspid regurgitation

A 59-year-old woman admitted to our hospital with shortness of breath and edema of the lower extremities was diagnosed with right ventricular failure stemming from severe tricuspid valve regurgitation (TR). She had undergone mitral valve replacement (MVR) with a mechanical valve at the age of 42. The approach to the heart was established via a right thoracotomy at the 4th intercostals space. A beating heart cardiopulmonary bypass procedure was performed in which tricuspid valve repair was performed with the edge-to-edge repair and MC3 annuloplasty system. The operative course was uneventful. This technique may be feasible and clinically effective in the treatment of severe TR.
