Key result
Intra-atrial anchored mechanical mitral valve replacement shows excellent hemodynamics in heavily calcified annuli.
Why the study?
Replacement of the mitral valve in the presence of extensive posterior annular calcification is a technical challenge with risks of prosthesis dehiscence and ventricular perforation.
Case Report (n=2)
A novel surgical technique using a single tilting disc mechanical valve with intra-atrial anchorage provides a feasible method for mitral valve replacement in patients with massive posterior annular calcification.

Should not yet change practice; leaves open feasibility in select anatomies pending prospective validation.
Kan et al. (1985) 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 two patients, showing excellent hemodynamic performance.
