Key result
Bifoil/trefoil catheters linked to ~19% greater mitral valve area increase vs Inoue balloons, but more shunting.
Why the study?
Results of percutaneous mitral valvotomy with Schneider-Medintag bifoil/trefoil catheters compared to the Inoue balloon were evaluated to assess differences in hemodynamic improvement and complications.
Does percutaneous mitral valvotomy with bifoil/trefoil catheters compared to the Inoue balloon improve hemodynamics in patients undergoing mitral valvotomy?

p-value: p=< 0.001
Bifoil/trefoil catheters provide a greater increase in mitral valve area compared to the Inoue balloon, but are associated with a higher incidence of inter-atrial shunting.
No takes yet. Share an insight, caveat, or question.
Bifoil/trefoil catheters were associated with larger mitral valve area yet more shunting than Inoue balloon; leaves open optimal device selection pending randomized trials.
Patel et al. (1993) conducted a cohort in Mitral stenosis (n=250). Schneider-Medintag bifoil or trefoil catheters vs. Inoue balloon was evaluated on Increase in mitral valve area (p=< 0.001). Percutaneous mitral valvotomy with bifoil/trefoil catheters yielded a greater increase in mitral valve area than the Inoue balloon (1.9 vs 1.6 cm2; P<0.001), but caused more inter-atrial shunting.
