Crush Stenting

A technique for stenting both the main coronary artery and the side branch; the side branch is stented with an uninflated balloon or a stent in the main vessel. The side branch is implanted with its proximal end protruding more than half the main vessel diameter into the main vessel. The side branch stent is crushed by the main vessel balloon/stent and the main vessel stented
Pros Limited plaque shifting, restored normal flow to all vessels, including the LIMA, and avoided devastating consequences of VA occlusion

A number of 2-stent techniques like T-stenting, crush stenting, culotte stenting, and simultaneous kissing stenting or Y-stenting ca be used with various levels of complexities and indications.
Crush stenting results in a triple layer of struts in the proximal main branch wall toward the branching vessel and a double layer of struts at the orifice of the SB.
In another multicenter prospective clinical trail, 134 bifurcation lesions in 132 patients were treated with the culotte technique and the incidence of stent thrombosis was 1.5% at 12 months.[sup][13] Regarding the crush stenting technique, a single center prospective registry study enrolled 100 patients treated with the crush technique.
found that bifurcation angle >50[degrees] is an independent predictor of MACE after bifurcation crush stenting. [sup][25] In our study, a wide bifurcation angle predicted SB occlusion after MV stenting.
Predictors of long-term outcome after crush stenting of coronary bifurcation lesions: Importance of the bifurcation angle.
For true bifurcation lesions involving two major branches, two stent procedures such as T-stenting, modified T-stenting, kissing stenting, or crush stenting were performed as previously described.
