J Am Coll CardiolPublished

  • Post hoc analysis of a randomised trial
  • 39 sites
  • echocardiographic core laboratory adjudication

Authors' conclusion

In this international trial with echocardiographic core laboratory adjudication, the rate of survival free from MV reoperation or any episode of severe MR during 2 years was 92% in patients with DMR and concomitant TV disease.
