Key result
Partial debridement and annular reconstruction with a bovine pericardial patch prior to mitral valve replacement successfully resolved mitral valve dysfunction and prevented further embolization.
Why the study?
There is currently no clear consensus on the optimal treatment strategy for CCMA, and surgical approaches face challenges.
Case Report (n=1)
Describes a refined surgical approach using partial debridement and annular reconstruction with a bovine pericardial patch prior to valve replacement for caseous calcification of the mitral annulus.
Suggests feasible technique for caseous mitral annular calcification; hypothesis-generating and requires validation in larger series.
Caseous calcification of the mitral annulus (CCMA) is a rare variant of mitral annular calcification (MAC), in which the core of the calcification undergoes a caseous transformation. CCMA can cause dysfunction of the mitral valve or embolization of caseous material, requiring surgery. There is currently no clear consensus on the optimal treatment strategy for CCMA. Attempts to address the condition, including surgical removal of calcification or mitral valve replacement, have faced certain challenges. This case details a refined approach consisting of partial debridement of the calcification and subsequent annular reconstruction with a bovine pericardial patch prior to surgical valve replacement.

Beyer et al. (2024) conducted a case report in Caseous calcification of the mitral annulus (CCMA) (n=1). Partial debridement and annular reconstruction with a bovine pericardial patch prior to mitral valve replacement was evaluated on Resolution of symptoms and prevention of further embolization. Partial debridement and annular reconstruction with a bovine pericardial patch prior to mitral valve replacement successfully resolved mitral valve dysfunction and prevented further embolization.
