Abstract
Mitral annular calcification (MAC) is a chronic, progressive, and degenerative process characterized by calcium deposition along the mitral annulus. This leads to stiffening and distortion of normal mitral annular architecture and ultimately MAC-related valvular dysfunction, which can manifest as mitral stenosis, mitral regurgitation, or mixed valvular disease. Due to its anatomic complexity, transcatheter and surgical interventions for MAC carry significant procedural challenges. As such, multi-modality imaging and multi-disciplinary heart team discussions are critical in MAC evaluation and procedural planning. This review summarizes the epidemiology and pathophysiology of MAC, highlights the critical role of multimodality imaging in the evaluation and procedural planning of MAC, and reviews established transcatheter mitral valve procedures and surgical options for managing MAC, MAC-related valvular dysfunction, and potential complications.
