Key result
Intra-atrial anchorage of larger tilting-disc mechanical mitral valves yields excellent hemodynamics in calcified annuli.
Why the study?
Replacement of the mitral valve in the presence of extensive posterior annular calcification is technically challenging with risks of prosthesis seating difficulties and complications.
Does a new technique using a larger single tilting disc mechanical valve with intra-atrial anchorage improve surgical outcomes in patients with massive posterior mitral annular calcification?

Does a new technique using a larger single tilting disc mechanical valve with intra-atrial anchorage improve surgical outcomes in patients with massive posterior mitral annular calcification?
A novel surgical technique using a single tilting disc mechanical valve with intra-atrial anchorage offers a feasible and safe approach for mitral valve replacement in patients with massive posterior annular calcification.

May offer an option in select anatomies; hypothesis-generating and requires prospective validation before any clinical consideration.
Kan et al. (1999) conducted a case report in Massive calcification of the posterior mitral annulus (n=2). Mitral valve replacement using a larger single tilting disc mechanical valve with intra-atrial anchorage was evaluated on Successful implantation and hemodynamic performance. Mitral valve replacement using a larger single tilting disc mechanical valve with intra-atrial anchorage was successfully performed in 2 patients, showing excellent hemodynamic performance.
