  Figure 1 Coronary angiographic findings. Severe stenosis involving bifurcation of the left anterior descending coronary artery (A). During the dissection spreads to the distal SB, blood flow was blocked (arrowhead; B). The guide extension catheter is inserted into the SB (C) and the final angiography (D).SB = side branch.

  Figure 2 A schematic representation of the ‘rescue’ balloon jailing and switch crush technique. Compromised SB (A). ‘Rescue’ balloon jailing technique with a small balloon (B). Inflation of the jailed SB with a larger balloon (C). Delivery of the guide extension catheter (D). The SB stent is inserted through the guide extension catheter (E, F). SB stent expansion (G). The final kissing balloon inflation (H) and the final result (I).SB = side branch.
