Implication
Successful PMV was associated with better 3-year survival in elderly patients; leaves open benefit versus medical therapy alone.
Structured PICO
Does percutaneous balloon mitral valvotomy improve long-term survival and clinical outcomes in patients aged 65 years and older?
P
Population
99 patients aged ≥65 years (mean age 72 ± 0.5 years, 81 women) undergoing percutaneous balloon mitral valvotomy. 84 patients were in NYHA class III or IV, 26 had previous surgical commissurotomy, 64 had comorbidities, and 73 had fluoroscopically visible mitral valve calcification.
I
Intervention
Percutaneous balloon mitral valvotomy (PMV)
C
Comparator
Unsuccessful PMV (observational comparison between successful and unsuccessful procedures)
O
Outcome
Immediate procedural success and long-term actuarial survival, survival without MV replacement, and survival without MV replacement and NYHA class III or IV at 3 yearshard clinical
Percutaneous mitral valvotomy can be performed safely in selected elderly patients, with procedural success leading to significantly improved long-term survival and freedom from valve replacement.
