Systematic Approach to the Calcified Mitral Valve Apparatus at Time of Mitral Valve Replacement

Mitral annular calcification (MAC) represents a surgical challenge to mitral valve replacement. The presence of MAC at the time of mitral valve replacement is associated with perivalvular leak and atrial-ventricular groove injury. Although percutaneous and hybrid approaches may offer alternatives to surgical mitral valve replacement, the early and late results from these techniques remain unknown. As such, the surgical management of MAC remains relevant in the contemporary treatment of patients with MAC. Herein, we present a systematic approach to the management of MAC at the time of mitral valve replacement.

Automated summary

MAC presents a surgical challenge to mitral valve replacement due to the associated perivalvular leak and atrial-ventricular groove injury. While percutaneous and hybrid approaches may offer alternatives, the outcomes of these techniques are still unknown. Therefore, surgical management of MAC remains relevant in the contemporary treatment of patients with MAC.
