A microsnare is then delivered antegradely and used to capture a retrogradely advanced externalization guidewire. Once snared, controlled traction is applied, inducing a longitudinal laceration of the vessel media and intima, which decompresses the subintimal hematoma at the bifurcation. We conducted a multicenter evaluation to assess the procedural feasibility and outcomes of this technique.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>SLASH was performed in 12 complex CTO PCI cases (mean J\u2010CTO score 3.5\u2009\u00b1\u20090.67). SLASH was successful in 10 (83%) cases, while technical and procedural success was achieved in 9 (75%) cases. In 2 cases, SLASH was unsuccessful due to an inability to deliver the microsnare sheath or failure to snare the retrograde guidewire. No cases of coronary perforation, emergent surgery, or other major procedural complications were observed. In one case, retrograde wire entrapment at a distal graft anastomosis was successfully resolved with rotational atherectomy\u2010induced wire fracture.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>SLASH is a feasible and effective technique for hematoma decompression and revascularization in bifurcation CTO PCI.
