Implication
May support repeat commissurotomy for mitral restenosis; extends observational data but leaves open randomized confirmation.
Structured PICO
Does repeat percutaneous mitral commissurotomy improve valve area and mid-term clinical outcomes in patients with symptomatic mitral restenosis?
P
Population
53 patients with symptomatic mitral restenosis (fusion of both commissures) a mean of 6+/-2 years after a successful first percutaneous mitral commissurotomy procedure.
I
Intervention
Repeat percutaneous balloon mitral commissurotomy (Inoue technique in 52 patients, double-balloon in 1 patient)
O
Outcome
Immediate results (valve area increase, good immediate results defined as valve area >=1.5 cm2 with no regurgitation >2/4) and 5-year survival rate without operation and in NYHA class I or IIcomposite
Repeat percutaneous balloon mitral commissurotomy is a valid and effective treatment for symptomatic restenosis, providing good immediate and mid-term results in appropriately selected patients.
