Key result
Perfusion balloon inflation in the outflow tract during transcatheter mitral valve-in-valve deployment successfully prevented left ventricular outflow tract obstruction in a high-risk patient.
Why the study?
Does inflation of a perfusion balloon in the outflow tract prevent LVOT obstruction during transcatheter mitral valve-in-valve replacement in a high-risk patient?

Does inflation of a perfusion balloon in the outflow tract prevent LVOT obstruction during transcatheter mitral valve-in-valve replacement in a high-risk patient?
Inflation of a perfusion balloon in the LVOT during transcatheter mitral valve-in-valve replacement may be a viable novel approach to prevent LVOT obstruction.

May avert LVOT obstruction in select high-risk mitral ViV cases; leaves open need for prospective validation before wider adoption.
Herrmann et al. (2017) conducted a case report in Transcatheter mitral valve-in-valve replacement with potential for LVOT obstruction (n=1). Perfusion balloon inflation in the outflow tract was evaluated on Left ventricular outflow tract (LVOT) obstruction. Perfusion balloon inflation in the outflow tract during transcatheter mitral valve-in-valve deployment successfully prevented left ventricular outflow tract obstruction in a high-risk patient.
