Conclusion
In summary, first data indicate that BVS behave similar compared with modern DES with regard to compromising or occluding side branches >0.5 mm. Smaller side branches might be compromised more often by BVS implantation compared with DES. It appears to be feasible to dilate side branches after crossing BVS cells, even though it may be technically more demanding compared with bifurcation procedures using solely DES. The safety of side branch dilatations remains open, but preliminary data suggest at least balloon diameters up to 2.5 mm can be used. Instead of kissing balloon dilatation, rather sequential balloon dilatation should be employed. It remains to be seen if BVS will also allow for treatment of rather complex bifurcation lesions. To our knowledge, no reports have so far been published related to BVS left main interventions. Certainly, more data are needed. As of today, BVS offer promise not only for the treatment of simple coronary lesions but also bifurcations. Given successful side branch protection, they might allow for restoring the native coronary anatomy in the sense of restitutio ad integrum.
