Key result
Inoue mitral valvuloplasty tracked over an arteriovenous wire loop was successful in a case where the standard transeptal antegrade approach failed to cross the stenotic mitral valve.
Case Report (n=1)
Tracking the Inoue balloon over an arteriovenous wire loop is a feasible bailout technique for difficult-to-cross stenotic mitral valves during percutaneous balloon mitral valvuloplasty.
Arteriovenous wire loop may enable Inoue valvuloplasty after failed standard crossing; leaves open need for validation before wider use.
Mitral stenosis is associated with significant morbidity and mortality. Percutaneous balloon mitral valvuloplasty is a standard treatment option for severe mitral stenosis, and in some patients may be the only feasible option. In patients with suitable valve anatomy and morphology, and with requisite physician expertise the procedure has a high success rate and good long-term outcomes. Nonetheless, even in appropriately selected patients the procedure can pose significant technical challenges. The transeptal antegrade approach using the Inoue Balloon system may be associated with difficulty and rarely with failure to cross the stenotic mitral valve. We report a case of initial Inoue balloon failure to cross followed by successful Inoue mitral valvuloplasty tracked over an arteriovenous wire loop.

Tandar et al. (2011) conducted a case report in Mitral stenosis (n=1). Inoue mitral valvuloplasty tracked over an arteriovenous wire loop was evaluated on Procedural success. Inoue mitral valvuloplasty tracked over an arteriovenous wire loop was successful in a case where the standard transeptal antegrade approach failed to cross the stenotic mitral valve.
