Double kissing mini-culotte stenting in unprotected distal left main bifurcation under optical coherence tomography guidance: immediate and short-term outcomes

Culotte stenting is an effective strategy for left main coronary bifurcation lesions. Increased side branch ostial restenosis is the main drawback of Culotte stenting. This is due to a napkin ring or potential gap produced at the ostium of the side branch. A bench study by Toth et al. has shown that additional sequential kissing balloon dilation before main vessel stenting can prevent this deformity.
