Key result
Final kissing balloon inflation increased the area of low wall shear stress (<0.5 Pa) from 62.3% to 79.0%, whereas a proposed tapered balloon reduced this area to 71.3%.

Does not support changing bifurcation stenting techniques; leaves open whether tapered balloons improve clinical outcomes.
Absolute Event Rate: 79% vs 62.3%
Sequential structural and fluid dynamic simulations reveal that while final kissing balloon inflation improves side branch blood flow, it increases mechanical stress and areas of low wall shear stress, which can be mitigated by a novel tapered balloon.
Morlacchi et al. (2011) studied Coronary bifurcations. Final kissing balloon (FKB) inflation vs. Before FKB / main branch stent inflation only was evaluated on Percentage of area characterized by wall shear stresses lower than 0.5 Pa. Final kissing balloon inflation increased the area of low wall shear stress (<0.5 Pa) from 62.3% to 79.0%, whereas a proposed tapered balloon reduced this area to 71.3%.
