Retrograde nontransseptal balloon mitral valvuloplasty. Immediate results and long-term follow-up.
Why the study?
Does percutaneous retrograde nontransseptal balloon mitral valvuloplasty improve mitral valve area and transmitral gradient in patients with a stenotic mitral valve?
Population
86 consecutive patients with a stenotic mitral valve (18 men, 68 women; mean age 51 +/- 11 years).

Implication
Should not yet change practice for mitral stenosis; leaves open comparative efficacy versus transseptal approaches.
Structured PICO

P
Population
86 consecutive patients with a stenotic mitral valve (18 men, 68 women; mean age 51 +/- 11 years).
I
Intervention
Percutaneous retrograde nontransseptal balloon mitral valvuloplasty using an externally steerable cardiac catheter.
O
Outcome
Mitral valve area and transmitral gradientsurrogate
Retrograde nontransseptal balloon mitral valvuloplasty effectively increases mitral valve area and decreases transmitral gradient with an acceptable safety profile, avoiding interatrial septum puncture.
