Excessive Fluid Causes Difficulties in MitraClip Implantation and Postoperative Fluid Management

Abstract

An 87-year-old man with worsening functional mitral regurgitation underwent transcatheter mitral valve repair under general anesthesia. Intraoperatively, we administered fluid aggressively to induce mitral regurgitation that had been reduced after anesthesia induction. Subsequently, cardiac dilatation due to the excessive fluid and device irrigation made it difficult to capture the mitral valve leaflets. Diuretics and catecholamines were required for several days after the procedure. Mitral regurgitation during transcatheter mitral valve repair should be induced with vasoconstrictors rather than through fluid administration.
