Key result
Transseptal balloon-assisted translocation of a mitral anterior leaflet (BATMAN) was performed first-in-human to facilitate transcatheter mitral valve replacement in severe calcification.
Why the study?
Is transseptal balloon-assisted translocation of a mitral anterior leaflet (BATMAN) feasible to facilitate transcatheter mitral valve replacement in a patient with severe mitral annular calcification at high risk of left ventricular outflow tract obstruction?
Is transseptal balloon-assisted translocation of a mitral anterior leaflet (BATMAN) feasible to facilitate transcatheter mitral valve replacement in a patient with severe mitral annular calcification at high risk of left ventricular outflow tract obstruction?
This first-in-human case report demonstrates a novel technique (BATMAN) to prevent LVOT obstruction during transcatheter mitral valve replacement in patients with severe mitral annular calcification.
We present a first in human experience of transseptal balloon-assisted translocation of a mitral anterior leaflet (BATMAN) to facilitate transcatheter mitral valve replacement in a patient with severe mitral annular calcification who was at high risk of left ventricular outflow tract obstruction.
