Key result
Balloon-assisted TMVR guidance yields stable valve function and hemodynamics through 3-year follow-up.
Why the study?
Mitral annular calcification related mitral stenosis presents a significant therapeutic challenge with limited procedural precision in transcatheter mitral valve replacement.

Supports feasibility of balloon-assisted TMVR in severe MAC; leaves open need for prospective validation before wider use.
Case Report (n=1)
A novel preseptostomy balloon-assisted trackability assessment can enhance procedural precision and trajectory optimization during TMVR for severe MAC.
Fabris et al. (2025) conducted a case report in Severe mitral stenosis with extensive mitral annular calcification (n=1). Transcatheter mitral valve replacement (TMVR) with preseptostomy balloon-based trackability assessment was evaluated. Transcatheter mitral valve replacement using a preseptostomy balloon-based trackability assessment resulted in a well-functioning valve and stable hemodynamics at 3-year follow-up.
