Key result
Modified transseptal BATMAN technique enables successful valve-in-valve TMVR in 3 severe bioprosthetic mitral stenosis cases.
Why the study?
LVOT obstruction is a high-risk complication in valve-in-valve TMVR, and anterior leaflet modification techniques like BATMAN may prevent it.
Does the modified transseptal BATMAN technique prevent left ventricular outflow tract obstruction in patients with severe bioprosthetic mitral stenosis undergoing high-risk transcatheter mitral valve-in-valve replacement?

Does the modified transseptal BATMAN technique prevent left ventricular outflow tract obstruction in patients with severe bioprosthetic mitral stenosis undergoing high-risk transcatheter mitral valve-in-valve replacement?
The modified transseptal BATMAN technique represents a feasible approach for anterior leaflet modification to prevent left ventricular outflow tract obstruction during high-risk transcatheter mitral valve-in-valve replacement.
May support anterior leaflet modification to avert LVOT obstruction in select high-risk TMVR; leaves open need for prospective validation.
The BATMAN (Balloon‐Assisted Translocation of the Mitral Anterior leaflet) technique, a novel approach for modifying the anterior leaflet during transcatheter mitral valve replacement (TMVR), has recently demonstrated efficacy in preventing left ventricular outflow tract obstruction (LVOT) which constitutes a high‐risk complication in valve‐in‐valve TMVR procedures. We describe three complex cases of severe bioprosthetic mitral stenosis who underwent successful valve‐in‐valve TMVR utilizing a modified transseptal BATMAN technique. We highlight the procedural methodology and explore the potential for this technique to be standard of care for valve‐in‐valve TMVR.

Golzarian et al. (2026) conducted a case report in Severe bioprosthetic mitral stenosis (n=3). Modified transseptal BATMAN technique was evaluated on Successful valve-in-valve TMVR. A modified transseptal BATMAN technique was successfully utilized in 3 complex cases of severe bioprosthetic mitral stenosis undergoing valve-in-valve transcatheter mitral valve replacement.
