Optimal time for collateral channel wiring in retrograde chronic total occlusion percutaneous coronary intervention.

ABSTRACT: Collateral channel wiring (CCW) is important in a retrograde chronic total occlusion (CTO) procedure. However, the guidance is insufficient. To investigate the optimal CCW time, patients who had received retrograde CTO procedures were enrolled. The optimal CCW time was derived by Receiver Operating Characteristic curves regarding success rates or complications. The clinical outcomes in terms of success and complication rates were addressed by cutoff value of optimal CCW time. With cutoff values of 25 min, 191 (54.9%) had shorter CCW times and 157 (45.1%) had longer CCW times. The success rates were significantly higher in the group with shorter CCW times than in the group with longer CCW times (p < 0.05).
