Patients elected to undergo mitral valve surgery (either repair or replacement) with less equal than moderate (≤+2) tricuspid regurgitation and dilated tricuspid annulus (>21mm/m2) at preoperative echocardiography will be screened. Consenting patients fulfilling all inclusion and exclusion criteria will be included in the study and assigned to elective mitral valve replacement or repair with or without concomitant tricuspid annuloplasty in a 1:1 fashion, using a blocked randomization scheme balanced within center.
The present study is designed as a prospective, multicentre, multinational, randomized, 2-arm parallel group trial. Participating centres are selected based on previous experience with the surgical technique and standardised echo imaging. Each center is expected to contribute 20 to 40 patients over a 12-month enrolment period.
Patients elected to undergo mitral valve surgery (either repair or replacement) with less equal than moderate (≤+2) tricuspid regurgitation and dilated tricuspid annulus (>21mm/m2) at preoperative echocardiography will be screened. Consenting patients fulfilling all inclusion and exclusion criteria will be included in the study and assigned to elective mitral valve replacement or repair with or without concomitant tricuspid annuloplasty in a 1:1 fashion, using a blocked randomization scheme balanced within center.
After discharge patients will be assessed at 1 month (phone contact), 6 month and 1-year after surgery.

| Mitral valve surgery | Procedure | Mitral valve repair is preferred whenever technically feasible over valve replacement. Annuloplasty may be used as sole therapy or in conjunction with other repair maneuvers to support the reconstruction and reinforce the annulus as well as prevent future annular dilatation. The mitral regurgitation secondary to myxomatous degeneration is prolapse of the middle scallop of the posterior leaflet result from chordal rupture or chordal elongation. Quadrangular resection of the involved middle scallop of the posterior leaflet combined with a posterior mitral annuloplasty is the best way to handle this situation. Chordae replacement could be used also to treat flail/prolapse of the anterior leaflet. Annuloplasty is always doing in mitral valve repair to stabilize and reshape the annulus. |

| Tricuspid valve annuloplasty | Procedure | Depending on the extent of the valve disease, there is the possibility to perform valve repair. In mitral valve reference center the rate of repair will reach 100%. In many patients with mitral valve regurgitation, tricuspid valve will be insufficient or the annulus dilated. Tricuspid annuloplasty ring will be helpful to treat dilation by reshaping, or to treat the regurgitant diseases. The ring will be secured and sutured to the native annulus by U-stitches. |
