Why the study?

Does catheter double-balloon valvuloplasty improve mitral valve area and what anatomic features influence the results in adults with rheumatic mitral stenosis?

Population

12 adult patients with rheumatic mitral stenosis

Comparison

Catheter double-balloon valvuloplasty (CBV) vs Baseline (before CBV)

Design

Cohort

Follow-up

Immediately after CBV

Implication

Subvalvular disease was associated with smaller post-CBV MVA; leaves open anatomy-guided selection for mitral valvuloplasty.

Key Points

This research aims to investigate how mitral valve anatomy affects area changes following double-balloon valvuloplasty in adults with mitral stenosis.
Conducted Doppler and two-dimensional echocardiography in 12 adults before and after double-balloon valvuloplasty.
Evaluated changes in mitral valve diameter and angulation post-procedure.
Analyzed the relationship between mitral valve area and anatomic features such as rigidity and calcification.
Mitral valve orifice diameter increased significantly from 18 mm to 25 mm (p < .001).
Post-valvuloplasty mitral valve area was greater in pliable valves (2.6 cm2) compared to rigid valves (1.9 cm2; p = .08).
Patients with subvalvular disease exhibited a smaller mitral valve area (2.0 cm2) than those without (2.9 cm2; p = .03).

Does catheter double-balloon valvuloplasty improve mitral valve area and what anatomic features influence the results in adults with rheumatic mitral stenosis?

Population

12 adult patients with rheumatic mitral stenosis

Intervention

Catheter double-balloon valvuloplasty (CBV)

Comparator

Baseline (before CBV)

Outcome

Mechanism of increase in mitral valve area (MVA) and anatomic features affecting results, measured by Doppler and two-dimensional echocardiographysurrogate

Catheter double-balloon valvuloplasty significantly increases mitral valve area in rheumatic mitral stenosis, with better results in patients lacking subvalvular disease.
