Acute Angiographic and Intermediate-Term Clinical Results of Patients with Non-Left Main Coronary Bifurcation Lesions Treated with BVS by Jailed Semi-Inflated Balloon Technique and Provisional Side-Branch Stenting Strategy

Figure 2

The steps of bioresorbable vascular scaffolding (BVS) implantation for a complex bifurcation lesion using the jailed semiinflated balloon technique (JSIBT). (a) Diagnostic coronary angiography (CAG) at LAO 26° and caudal 28° projection showed a true proximal left anterior descending (LAD) artery bifurcation lesion (Medina classification 1.1.1). (b) Wiring of the main vessel (MV) LAD and side branch (SB) and balloon dilatation of the MV. (c) Balloon dilatation of the diagonal SB and BVS was advanced to middle of the MV. (d) JSIBT with simultaneous inflation of BVS and a semicompliant balloon. The SB balloon is inflated to a low pressure (4 atmospheres) and BVS less than nominal pressures. (e) For optimization of the MV scaffold, the proximal optimal technique was performed with a short noncompliant balloon. (f) Final CAG at LAO 1° and cranial 32° projection showed a good angiographic result and bifurcation flow.
