Abstract

OBJECTIVES:

The most common re-entry technique during retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is reverse controlled antegrade and retrograde tracking (rCART). The use of guide-catheter extensions can facilitate rCART, but has received limited study.

METHODS:

We compared the clinical and procedural characteristics and outcomes of traditional rCART vs guide-catheter extension rCART vs cases in which both techniques were used (combined rCART) in patients with successful retrograde CTO crossing in a contemporary multicenter CTO-PCI registry.

RESULTS:

Between 2012 and 2018, rCART was used in 467 of 1336 retrograde CTO-PCI cases. Guide-catheter extension rCART was used in 60/467 cases (13%; use increased from 0% in 2012 to 26% in 2017). The traditional rCART group, guide-catheter extension rCART group, and combined rCART group had similar target lesion J-CTO scores (3.3 ± 1.1 vs 3.2 ± 1.2 vs 3.6 ± 0.8, respectively; P=.28), technical success rates (99% vs 100% vs 96.4%, respectively; P=.36), procedural success rates (93.2% vs 93.8% vs 96.3%, respectively; P=.82), and major in-hospital adverse cardiac event (MACE) rates (6.4% vs 9.4% vs 3.6%, respectively; P=.66). Total procedural time was longer in the combined rCART group (196 min [IQR, 146-256 min] vs 200 min [IQR, 164-293 min] vs 255 min [IQR, 195-280 min], respectively; P<.01), with a trend for lower patient air kerma radiation dose in the guide-catheter extension groups (4.11 Gray [IQR, 2.49-5.77 Gray] vs 3.19 Gray [IQR, 1.29-4.74 Gray] vs 3.47 Gray [IQR, 2.89-5.56 Gray]; P=.07).

CONCLUSIONS:

Guide-catheter extension rCART is increasingly being used for retrograde CTO crossing and is associated with similar success and MACE rates as traditional rCART.
