Why the study?
Does the double balloon technique improve procedural outcomes compared to the single (Inoue) balloon technique in patients with symptomatic mitral stenosis?

Both double and single balloon techniques are useful and safe for mitral valvuloplasty, though the double balloon technique yields a significantly greater final mitral valve area.
No takes yet. Share an insight, caveat, or question.
May support double balloon for larger valve area gains in mitral stenosis; leaves open superiority over Inoue balloon pending randomized data.
Rihal et al. (1993) studied this question.
