• creates controlled incision planes which help to relieve hoop stress• allows dilatation at lower pressures
“Cutting-balloon angioplasty effectively facilitates the interventional procedure
and leads to a low rate of recurrent stenosis in ostial bifurcation coronary
lesions: It is associated with a low rate of binary stenosis and TLR.”
CBA did not reduce recurrent ISR and major adverse cardiac events, as
compared with conventional POBA.
However, CBA was associated with procedural advantages, such as use
of fewer balloons, less requirement for additional stenting, and lower incidence
of balloon slippage.
