Minimally Invasive Hybrid Approach to High Risk Mitral Disease With Severe Mitral Annular Calcification

Published:December 12, 2019DOI:https://doi.org/10.1016/j.cjca.2019.12.008

      Abstract

      Severe circumferential mitral annular calcification (MAC) remains a significant challenge, complicating surgical treatment of mitral valve disease. Transcatheter treatment options are attractive; however, they remain fraught with risks of annular fixation, paravalvular leak, atrioventricular-groove disruption, and left-ventricular outflow tract obstruction. We describe a novel minimally invasive hybrid technique of transcatheter mitral valve replacement in a patient with severe circumferential MAC.

      Résumé

      La calcification circonférentielle sévère de l’anneau mitral reste un problème important qui complique le traitement chirurgical de la valvulopathie mitrale. Les options de traitement percutané sont tentantes; elles continuent toutefois de présenter un risque de fixité annulaire, de fuite paravalvulaire, de perturbation du sillon auriculo-ventriculaire et d’obstacle à l’éjection ventriculaire gauche. Nous décrivons une nouvelle technique hybride de remplacement valvulaire mitrale par cathéter à effraction minimale chez un patient présentant une calcification circonférentielle grave de l’anneau mitral.
