New approaches to ostial and bifurcation lesions

Abstract

Percutaneous coronary intervention of bifurcation lesions is associated with lower procedural success rates, and an increased subsequent rate of major adverse cardiac events and restenosis. Currently, an array of stenting possibilities suggests a rational approach to treat various bifurcation lesions with appropriate techniques. This is however seldom the case. The main problems of treating bifurcation lesions remain plaque shift leading to (threatened) side branch occlusion, and either too much or insufficient side branch ostial stent coverage predisposing to impaired side branch access or restenosis, respectively. This paper reviews the available technologies and their relative merits.
