ABSTRACT

INTRODUCTION - We examined the impact of proximal vessel tortuosity on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI).


METHODS - The baseline clinical and angiographic characteristics and procedural outcomes of 1618 consecutive CTO-PCIs performed between 2012 and 2016 at 14 United States centers in 1589 patients were reviewed.


RESULTS - Mean patient age was 65.3 ± 10.0 years and 85% were men. Moderate/severe proximal vessel tortuosity was present in 35.7% of target lesions. Compared with non-tortuous lesions, tortuous lesions had longer length (30 mm [interquartile range, 20-50 mm] vs 28 mm [interquartile range, 16-40 mm]; P<.001), more proximal cap ambiguity (36% vs 28%; P<.01), and more frequent utilization of the retrograde approach (52% vs 37%; P<.001). Moderate/severe proximal vessel tortuosity was associated with lower technical success rates (84.1% vs 91.3%; P<.001) and procedural success rates (82.3% vs 89.9%; P<.001), but similar incidence of major cardiac adverse events (3.0% vs 2.5%; P=.59). Moderate/severe tortuosity was associated with longer procedure time and fluoroscopy time, higher air kerma radiation dose, and larger contrast volume.


CONCLUSION - In a contemporary multicenter registry, moderate/severe proximal vessel tortuosity was present in approximately one-third of target CTO lesions and was associated with more frequent use of the retrograde approach and lower success rates, but similar complication rates.
