Abstract
Mitral regurgitation (MR) is a common condition causing significant morbidity and
mortality in the Western world. Although surgical therapy has developed over 5 decades
to provide solutions, only a minority of patients undergo surgery. The last decade
has seen the emergence and application of multiple transcatheter techniques in attempts
to address this undertreated population with the large clinical experience of MitraClip
providing the most insight. Clear understanding of the pathophysiology of different
MR types as well as the role of particularly secondary MR on patient's clinical syndrome
allow for better prediction as to which patient subgroups will benefit from different
repair techniques or intervention at all. Most of the techniques are based on surgical
technique and are applied as single-device/technique solutions, whether leaflet, chordal,
or annular solutions, but with broadening experience, combination therapies are likely
to find a place in creating a more complete and surgical-like solution.
Résumé
L'insuffisance mitrale (RM) est une affection courante qui entraîne une morbidité
et une mortalité importantes dans le monde occidental. Bien que les traitements chirurgicaux
se soient développés au cours des cinq dernières décennies pour y apporter des solutions,
seule une minorité de patients est opérée. La dernière décennie a vu l'émergence et
la mise en œuvre de nombreuses techniques de transcathéterisme pour tenter de soigner
cette population sous-traitée, et la vaste expérience clinique du MitraClip en apporte
le meilleur aperçu. Une compréhension claire de la pathophysiologie des différents
types de IM ainsi que du rôle d'une IM secondaire notamment sur le syndrome clinique
du patient permet de mieux prédire quels sous-groupes de patients bénéficieront de
différentes techniques de réparation ou d'une intervention en tant que telle. La plupart
des techniques sont basées sur une méthode chirurgicale et sont appliquées comme des
solutions à dispositif/technique unique, qu'il s'agisse de solutions ciblant les feuillets,
les cordages ou l'anneau mitral, mais avec l'élargissement de l'expérience acquise,
les thérapies combinées sont susceptibles de trouver une place dans l'élaboration
d'une solution plus complète et de type chirurgical.
