A Challenging Case of MitraClip on a Tricuspid Valve With a Redundant Eustachian Valve: Surfing Into the Right Atrium

Abstract

Transcatheter tricuspid valve intervention is gaining importance due to the development of percutaneous techniques addressing tricuspid regurgitation. The presence of a redundant eustachian valve can increase procedural complexity by restricting the manipulation of transcatheter devices. We present a case of torrential tricuspid regurgitation and a redundant eustachian valve hampering the manipulation of the delivery system. We were able to reach the tricuspid valve by looping 2 standard guidewires into the atrium. We performed a tricuspid-plasty by implanting 2 MitraClips with a satisfactory final result. This technique can be applied when the eustachian valve impairs navigation in the right atrium.
