Patients with coronary artery disease where a lesion is located at a vessel bifurcation and extends into the side branch can be difficult to treat in a cath lab. The conventional treatment for bifurcations is to either used a single stent and leaving part of the vessel untreated, or use of two stents. Use of two stents can "cage" or "jail" the side branch vessel because of the stent struts in the main vessel. This might prevent future access to treat the side branch vessel. This channel offers news on bifurcation treatment strategies and development of dedicated side branch stents.
