Abstract

We sought to examine the impact of calcific deposits on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). The outcomes of 1,476 consecutive CTO PCIs performed in 1,453 patients (65.5 ± 10 years, 85% male) between 2012 and 2016 at 11 US centers were evaluated. Moderate or severe quantity of calcium was present in 58% of target lesions. Calcified lesions were more tortuous and more likely to have proximal cap ambiguity and interventional collaterals. PCI of moderately/severely calcified CTOs more often required use of the retrograde approach (54% vs 30%, p

Abstract

We sought to examine the impact of prior failure on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We examined the clinical and angiographic characteristics and procedural outcomes of 1,213 consecutive patients who underwent 1,232 CTO PCIs between 2012 and 2015 at 12 US centers. Mean age was 65 ± 10 years and 84.8% of patients were men. A prior failed attempt had been performed in 215 (17.5%) patients. As compared with patients without prior CTO PCI failure, patients with prior failure had higher Japanese Chronic Total Occlusion (J-CTO) score (2.40 ± 1.13 vs. 3.28 ± 1.29, p
