Fewer adverse events with 'double kissing' crush stent than culotte

The DKCRUSH-III trial shows that double kissing crush stenting reduces restenosis and improves long-term outcomes for patients with bifurcation lesions, a type of complex coronary lesion. The study found 6.8% in-stent restenosis rates with double kissing crush versus 12.6% with culotte stenting.
