ABSTRACT

Bifurcation lesions represent a complex subset of coronary artery disease, accounting for approximately 15- 20% of percutaneous coronary interventions (PCI). These lesions carry a high risk of restenosis, thrombosis, and procedural complications. The Proximal Optimization Technique (POT) is a critical method designed to optimize stent expansion, particularly in the proximal main vessel (pMV), using balloons sized to the pMV diameter inflated at high pressures to enhance stent apposition.

This article details the technical steps of POT, emphasizing the significance of proper equipment selection and precise balloon positioning. The clinical outcomes, management of complications, and the efficacy of POT are also discussed. Data from clinical studies indicate that POT effectively reduces restenosis and stent thrombosis rates. Advanced imaging techniques (IVUS, OCT) and supplementary optimization strategies are recommended to manage potential complications and improve procedural success.

In conclusion, the accurate application of POT in bifurcation PCI is pivotal for improving both short- and long- term clinical outcomes. This technique has become an indispensable tool in interventional cardiology, partic- ularly for managing the complexities of bifurcation lesions.
