  • Title: A Case of Catheter-Based Tricuspid Valve Repair Reversing the Previous Success of Transcatheter Mitral Valve Repair: A New Scenario Requires New Answers.

    Abstract:
    Concomitant severe mitral-tricuspid regurgitation is observed in up to 30% of patients with reduced left ventricular ejection fraction. In symptomatic subjects at high surgical risk, transcatheter treatment is a viable option in the presence of suitable anatomy. We present a case of mitral regurgitation worsening after TriClip (Abbott, Abbott Park, IL) implantation in a patient with a previous successful MitraClip (Abbott) intervention. The correction of tricuspid regurgitation by catheter repair improves overall hemodynamics, but it can sometimes paradoxically worsen mitral regurgitation, as herein displayed. Clinical care is needed to detect tricuspid regurgitation repair-induced worsening of mitral regurgitation and ensure optimal management.
