Abstract
Mitral annular calcification (MAC) is a chronic degenerative process that implies calcification on the mitral support structure. It usually appears as a bystander to other cardiac pathologies hindering surgical treatment and increasing morbidity and mortality. When addressing the mitral valve, many surgical strategies have been suggested in the past with no clear consensus on what to choose. Moreover, and as transcatheter therapies have gained popularity over the last few decades, transcatheter mitral valve implantation has appeared as another alternative to conventional surgery. In this review, we aim at describing an overview of MAC, highlighting current challenges and treatment options as well as new potential alternatives.
