Abstract
Percutaneous coronary intervention (PCI) of coronary artery bifurcation lesions entails technical challenges and carries a higher risk of adverse events on follow-up, driven by repeat revascularisation and stent thrombosis. While most bifurcations can be tackled with a provisional (single-stent) approach, more complex lesions involving both branches (true bifurcation lesions) require a two-stent approach. In the latter context, several techniques have been proposed. Among them, the crush technique has dramatically evolved in recent years, and its more recent iterations have been shown to provide excellent and durable results, both for left main and non-left main bifurcations. The aim of the present work is to discuss the technical aspects and outcomes of the variants of the crush technique from the first description in the early 2000s to the present day.
