Prophylactic Tricuspid Valve Annuloplasty in Patients Undergoing Mitral Valve Surgery

Not Applicable

• Conditions: Tricuspid Valve Insufficiency

• Registration Number: NCT01580436
• Lead Sponsor: Hasselt University

Brief Summary

De novo or progressive tricuspid regurgitation (TR) is not uncommonly observed following mitral valve surgery and associated with worse outcome. Hence, concomitant tricuspid valve annuloplasty (TVP) has been recommended for patients undergoing mitral valve surgery when tricuspid annular dilatation is present even in absence of significant TR. However, whether such a strategy of "prophylactic TVP" results in improved outcomes has not been shown to date by a prospective randomized study. The investigators goal is therefore to initiate such a study and evaluate the effect of concomitant TVP on mid- and long-term outcome in patients scheduled for mitral valve surgery and tricuspid annular dilatation but \<2+ TR.
