Simultaneous kissing stents to treat unprotected left main stem coronary artery bifurcation disease; stent expansion, vessel injury, hemodynamics, tissue healing, restenosis, and repeat revascularization.

ABSTRACT:

Objectives

To perform detailed analysis of stent expansion, vessel wall stress, hemodynamics, re-endothelialization, restenosis, and repeat PCI in the simultaneous kissing stents (SKS) technique of bifurcation left main stem (LMS) stenting.

Background

The SKS technique is useful to treat patients with true bifurcation disease of the LMS but remains controversial.

Methods and results

Computational structural analysis of SKS expansion demonstrated undistorted and evenly expanded stents. Computational fluid dynamics modelling revealed largely undisturbed blood flow. 239 PCI procedures were performed on 217 patients with unprotected bifurcation LMS disease with SKS using DES (2004-2017). We electively studied 13 stable patients from baseline to 10 years post-SKS with repe
