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.
