In a left main trifurcation bench model, simultaneous trissing improved stent expansion at the polygon of confluence compared to serial kissing ballooning (23.7 vs. 21.1 mm2; P=0.043).
Do different side-branch rewiring and ballooning techniques influence stent configuration, expansion, and apposition in left main trifurcation provisional stenting?
In a bench model of left main trifurcation, provisional stenting strategies are feasible, and side-branch rewiring and ballooning techniques influence stent fenestration geometry but have limited impact on overall stent expansion and apposition.
Absolute Event Rate: 23.7% vs 21.1%
p-value: p=0.043
All provisional stenting strategies tested were technically feasible for left main trifurcations. SB rewiring and ballooning technique influenced stent configuration, particularly the number and size of fenestrations, but had limited impact on overall stent expansion and apposition.
Mâaroufi et al. (2026) studied Left main coronary trifurcation (n=12). Simultaneous trissing ballooning vs. Serial kissing ballooning was evaluated on Minimal stent area at the polygon of confluence (µCT) (p=0.043). In a left main trifurcation bench model, simultaneous trissing improved stent expansion at the polygon of confluence compared to serial kissing ballooning (23.7 vs. 21.1 mm2; P=0.043).
