Abstract

Background: Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention (CTO PCI) according to target vessel have received limited study.

Methods: We compared clinical, angiographic, procedural characteristics and outcomes of 1,568 right coronary artery (RCA), left anterior descending artery (LAD) and Left Circumflex (LCX) CTO PCIs with follow-up outcomes available.

Results: Mid RCA was the most common target vessel (Figure 1). The J-CTO score was 2 [1,3] vs 3 [2,4] vs 3 [2,4], p<0.0001 (LAD vs LCX vs RCA respectively). Technical success was lower in RCA (89% vs 85% vs 84%, p=0.05). In-hospital MACE did not differ significantly (2.7% vs 4.8% vs 2.9%, p=0.3). LCX CTO had higher incidence of the composite of death, myocardial infarction (MI) and revascularization rates at 1 year (Figure 2) (plog-rank=0.05).

Conclusions: LCX lesions are associated with the worst and RCA lesions with the best 1-year outcomes, while LAD CTOs are the least complex. (Figure Presented) .
