Surgical implantation of a complete or incomplete ring to reduce the valve annulus and improve leaflet coaptation is the mainstay of mitral valve surgery. The Cardioband® system (Edwards Lifesciences) was designed to address the pathophysiological mechanism of annular dilatation through a catheter‐based approach. We present the histopathological workup of a Cardioband® device, which had been implanted 21 months earlier in a 34‐year‐old male with ischemic cardiomyopathy. Device examination demonstrate a well‐positioned and securely anchored device. The described tissue reactions may have an impact on choice of device and timing in case of re‐do surgery.
