ABSORB BVS Implantation in Bifurcation Lesions - Current Evidence and Practical Recommendations

The introduction of the ABSORB bioresorbable vascular scaffold (BVS) provides a new tool for stenting in interventional cardiology. Initially, relatively simple coronary artery lesions were treated with this novel device; nowadays, we are gaining clinical experience when treating a wide variety of lesions with the ABSORB BVS, including bifurcation lesions. Unfortunately, data are limited in terms of the use of the ABSORB BVS in coronary bifurcation lesions, so little is known about the safety and feasibility of these procedures. Bench testing and case reports showed that single provisional scaffold placement is feasible with fenestration of the scaffold towards the side branch and sequential non-compliant balloon inflation in the side and main branches. However, no prospective randomised clinical data with optical coherence tomography (OCT) imaging for different bifurcation stenting techniques are available. Based on the available data and our own experience we would recommend the use of the provisional single scaffold technique and only to fenestrate the scaffold if a severely pinched ostium combined with impaired flow seen on angiogram.
