Abstract

Abstract Mitral regurgitation is associated with a worsened prognosis in dilated cardiomyopathy. First standard therapy consists of a mitral valve reconstruction through heart surgery including the heart–lung machine. In patients with high comorbidity, catheter-based techniques have been developed. In the Evolution I study, the MONARC system was implanted in the coronary sinus in the functional mitral regurgitation. A reduction in regurgitation by >1 grade was documented in 50% of the patients. MitraClip is an alternative, edge-to-edge technique, which joined the posterior and anterior leaflet by implanting a clip. It can be used for both functional and degenerative mitral regurgitations. We reported a case of MitraClip procedure with the use of two clips and a reduction of mitral regurgitation to grade 0–1 after implanting a MONARC device four years ago with missing relevant reduction in mitral regurgitation. With this report, we illustrated the management of Mitraclip in a patient with an implanted MONARC device and technical difficulties through the bowing of the posterior annulus.

Highlights

  • Mitral regurgitation in dilated cardiomyopathy is often a functional reason of either ischemic or idiopathic origin

  • We reported a case of MitraClip procedure with the use of two clips and a reduction of mitral regurgitation to grade 0–1 after implanting a MONARC device four years ago with missing relevant reduction in mitral regurgitation

  • In the Evolution I study, a patient with functional mitral regurgitation between 2+ and 4+ revealed at 12 months a reduction by >1 grade in 50%, that is less than what it obtained with surgical mitral valve repair
