Unnatural milieu: Thrombus after transcatheter mitral valve replacement

Key Points

• What the article teaches

  Transcatheter heart valve thrombosis in the mitral position causes increased valve gradients, valve dysfunction, and symptoms, and may be associated with lack of therapeutic anticoagulation.

• How it will impact practice

  Anticoagulation with a vitamin K antagonist should be considered in all patients undergoing transcatheter mitral valve replacement.

• What new research/study would help answer the question posed

  Efficacy, optimal duration, and safety of anticoagulation therapy, balancing reduced thrombosis against increased bleeding risk, needs to be assessed in larger cohort studies and prospective trials.
