Key result
Mitral valve replacement for calcified annulus achieves 0% hospital mortality with no superior surgical technique.
Why the study?
Standard suture techniques for mitral annulus calcification may cause fracture and paravalvular leak, necessitating evaluation of alternative surgical methods.
What are the outcomes of different surgical techniques for mitral valve replacement in patients with a calcified mitral annulus?
Observational (n=17)
What are the outcomes of different surgical techniques for mitral valve replacement in patients with a calcified mitral annulus?
Various surgical techniques for mitral valve replacement in patients with calcified mitral annulus can be performed safely with good functional outcomes, with no single technique proving clearly superior.
No takes yet. Share an insight, caveat, or question.
Alternative mitral annulus techniques may limit paravalvular leak in calcification; leaves open optimal method for larger prospective validation.
Mills et al. (1986) conducted an observational in Mitral annulus calcification (n=17). Mitral valve replacement techniques (suture through calcified annulus, decalcification, onlay patch, drill technique) was evaluated on Hospital deaths and functional improvement. Mitral valve replacement using four techniques for calcified mitral annulus in 17 patients resulted in 0 hospital deaths and functional improvement, with no single technique clearly advantageous.
