Rewiring to the dissected branch along the jailed balloon (Real JAB technique)-A novel rewiring technique for the dissected branch in bifurcation lesion-case report.

Guidewire recrossing into the branch through the stent strut is difficult when that branch was injured or occluded after stenting in the true bifurcation lesion. A 72-year-old man with chronic total occlusion in both mid-left anterior descending coronary artery (LAD) and 2nd diagonal branch (D) was admitted to our hospital. We put a 2.25 × 38 mm drug-eluting stent from the LAD to the D with culotte stenting. However, the LAD occluded after stenting. Although we tried to recross, it was impossible because the guidewire migrated subintimal space which was caused by guidewire manipulation. So, we advanced a 2.25 mm balloon catheter on the 1st guidewire which had already been placed outside of the stent in the LAD, and inflated it at bifurcation to compress the subintimal space. Subsequently, we advanced another guidewire through the strut along the surface of the balloon catheter. Immediately after the deflation of the balloon, the guidewire slipped into the distal LAD without resistance. Large branch occlusion after stenting is a serious complication in true bifurcation treatment. Our new bailout technique is effective for recrossing a guidewire into the dissected branch to preserve it. <Learning objective: In the treatment of bifurcation, the dissection at the branch ostium is a major cause of rewiring failure or periprocedural myocardial infarction. The Real JAB (Rewiring to the dissected branch along the jailed balloon) technique is a useful technique to re-cross the wire into the dissected branch. The principle of this technique is to occupy subintimal space with dilated jailed balloon that is used as navigator of guide wire into distal true lumen.>.
