Implication
Single case does not support practice change; leaves open comparative effectiveness of single large-balloon mitral valvuloplasty.
Structured PICO
Does single large-balloon percutaneous mitral valvuloplasty improve mitral valve area in patients requiring valvuloplasty?
P
Population
6 patients undergoing percutaneous balloon mitral valvuloplasty
I
Intervention
Single large-balloon (up to 30 mm diameter) percutaneous mitral valvuloplasty
O
Outcome
Mitral valve areasurrogate
Single large-balloon percutaneous mitral valvuloplasty effectively increases mitral valve area without significant complications, offering a potentially simpler alternative to the double-balloon technique.
