Impacts of Lesion Characteristics on Procedures and Outcomes of Chronic Total Occlusion Recanalization With Antegrade Guidewire True Lumen Tracking Techniques: A Substudy of Taiwan True Lumen Tracking Registry. Front Cardiovasc Med 2022; 9:769073. [PMID: 35299982 PMCID: PMC8921496 DOI: 10.3389/fcvm.2022.769073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Accepted: 01/31/2022] [Indexed: 11/16/2022] Open
Abstract
Background Lesion characteristics were shown to predict procedural success and outcomes in chronic total occlusion (CTO) recanalization. However, diverse techniques involved in these studies might cause potential heterogeneity. Objective The study aimed to test the impacts of lesion characteristics on CTO intervention with a pure antegrade wiring-based technique. Methods and Results We studied consecutive 325 patients (64.5 ± 11.1 years, 285 men) with native CTO lesions intervened by a single operator with an antegrade-based technique between August 2014 and July 2020. Forty-seven patients with antegrade procedural failure (20 with pure antegrade wiring failure and 27 with back-up retrograde techniques) were compared to 278 patients with antegrade-only procedural success. With a median follow-up of 30.8 (16.1–48.6) months, 278 patients with procedural success were further assessed for target vessel failure (TVF: cardiac death, target vessel myocardial infarction [MI], and target lesion revascularization [TLR]). Patients with antegrade procedural success had a lower percentage of history with bypass graft (4 vs. 15%, p = 0.004) and lower Multicenter Chronic Total Occlusion Registry of Japan (J-CTO) score (2.1±1.3 vs. 3.4 ± 1.0, p < 0.001), when compared to those with antegrade failure. The J-CTO score was independently associated with procedural failure (odds ratio = 2.5, 95% CI = 1.8–3.4) in multivariate analysis. However, only clinical features, such as female gender (hazard ratio [HR] = 4.3, 95% CI = 1.4–13.1), estimated glomerular filtration rate <60 ml/min/1.73 m2 (HR = 3.2, 95% CI = 1.0–9.9), and old MI (HR = 4.5, 95% CI = 1.5–12.8), but not J-CTO score, could predict long-term TVF in multivariate Cox regression model. Conclusion The feasibility of the antegrade guidewire-crossing technique for native CTO intervention was highly determined by lesion characteristics. With such a simpler technique, the prognostic impact of lesion complexity shown in studies with multiple recanalization techniques was negligible. This suggested antegrade true lumen tracking techniques deserved to be tried better even for CTO lesions with higher complexity.

Abstract
Background The new EuroCTO CASTLE Score was validated against the widely adopted Japanese Multicenter CTO Registry (J-CTO) score in predicting technical success in percutaneous coronary intervention (PCI) for coronary chronic total occlusions (CTO). Methods A total of 463 patients treated by CTO PCI were included in a retrospective analysis. Result: The mean CASTLE score was 2.23 ± 1.1 and J-CTO score was 2.84 ± 1.0. The overall technical success rate was 83.2%. At 30 days follow up, a primary composite safety endpoint showed a low proportion of stent thrombosis (0.2%) and re-hospitalization (0.4%). Moreover, an improvement of clinical symptoms was found in 83% of patients. Receiver operating characteristic analysis (ROC) demonstrated a comparable overall discriminatory performance in predicting technical outcome: CASTLE score, area under the ROC curve (AUC) 0.668, 95% CI: 0.606–0.730; J-CTO score AUC 0.692, 95% CI: 0.631–0.752; Comparison of AUCs: p = 0.324. Those findings were even consistent in more complex procedures CASTLE Score ≥ 4 and J-CTO score ≥ 3: CASTLE Score AUC 0.514, 95% CI: 0.409–0.619; J-CTO score, AUC 0.617, 95% CI: 0.493–0.741; Comparison of AUCs: p = 0.211. Furthermore, increasing score values are accompanied by a longer examination and fluoroscopy time, more contrast medium and a higher dose area product. Conclusion Compared to the widely accepted J-CTO score, the new introduced EuroCTO CASTLE score demonstrated a comparable overall discriminatory performance in predicting technical outcomes in CTO PCI.

Abstract
Revascularisation of chronic total occlusion (CTO) represents one of the most challenging aspects of percutaneous coronary intervention, but advances in equipment and an understanding of CTO revascularisation techniques have resulted in considerable improvements in success rates. In patients with prior coronary artery bypass grafting (CABG) surgery, additional challenges are encountered. This article specifically explores these challenges, as well as antegrade methods of CTO crossing. Techniques, equipment that can be used and reference texts are highlighted with the aim of providing potential CTO operators adequate information to tackle additional complexities likely to be encountered in this cohort of patients. This review forms part of a wider series where additional aspects of patients with prior CABG should be factored into decisions and methods of revascularisation.

Abstract
BACKGROUND Long lesions are known to have worse outcomes following percutaneous coronary intervention (PCI), but there are limited data assessing the association between lesion length and clinical outcomes in PCI procedures undertaken in chronic total occlusions (CTO). METHODS AND RESULTS We formed a longitudinal cohort (2006-2018, n = 27,205) of stable angina patients who underwent PCI to CTO in the British Cardiovascular Intervention Society (BCIS) database. Clinical, demographical, procedural, and outcome data were analyzed in three groups by treated segment length, < 30 mm (n = 11,782), 30-59 mm (n = 10,415), ≥ 60 mm (n = 5008). Prevalence of previous myocardial infarction and PCI were higher in patients in 30-59 mm group or ≥ 60 mm group compared with < 30 mm group. Following multivariable analysis, no significant difference was observed in in-patient death (OR = 30-59 mm group = 1.10, CI:0.55-2.19, p = 0.78) (OR ≥ 60 mm group = 0.82, CI: 0.33-2.05, p = 0.67), and 1-year death (OR = 30-59 mm group = 1.06, CI: 0.81-1.37, p = 0.69) (OR ≥ 60 mm group =1.01, CI: 0.70-1.43, p = 0.99) (< 30 mm group = reference) but in-patient MACE was higher in > = 60 mm group (OR: 1.52, CI: 1.15-2.01, p = 0.06) but similar in 30-59 mm group (OR: 1.16, CI: 0.91-1.48, p = 0.22) compared with < 30 mm group. The adjusted rates of procedural complications were higher in ≥ 60 mm group (OR: 1.61, CI: 1.40-1.85, p < 0.001) but were similar in 30-59 mm group (OR: 1.06, CI: 0.94-1.20, p < 0.31) compared with < 30 mm group. For every 10 mm increase, there was an increased adjusted risk of in-patient procedural complications and coronary perforation but not in-patient MACE or death. CONCLUSION Patients with very long CTO lesions have higher risk of procedural complications and in-patient MACE but similar risk of short or long-term mortality compared with short CTO lesions.

Abstract
Percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) is considered relatively complex with low success rates and high complication rates. Treating a CTO with PCI using the hybrid algorithm increases success rates with acceptable complication rates. An essential part of the hybrid algorithm is antegrade dissection and reentry (ADR). In PCI of a non-CTO coronary lesion, the guidewire over which the stent is advanced and placed stays within the true lumen of the coronary artery. ADR techniques make it possible to cross the lesion through the wall of the coronary artery, the subintimal space, thus creating a small bypass within the architecture of the coronary artery and restoring antegrade blood flow. ADR increases success rates, especially in more difficult CTO procedures. In the last decade, new materials and techniques have been introduced in quick succession, which are summarised in this review. Consequently an updated ADR algorithm is presented, which can support the CTO operator during an ADR procedure.

Abstract
The clinical outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in prior coronary artery bypass graft (pCABG) patients have been investigated; however, the results are inconsistent.The present meta-analysis compared the clinical outcomes of CTO PCI in patients with and without prior CABG (nCABG). The endpoints included technical success, procedural success, all-cause mortality, myocardial infarction (MI), major bleeding, coronary perforation, pericardial tamponade, emergency CABG, and vascular access complication.A total of 7 studies comprising of 11099 patients were included in this meta-analysis. The results showed that compared to nCABG patents, pCABG patients were associated with lower technical success (82.3% versus 87.8%; OR, 0.60; 95% CI, 0.53-0.68; P < .00001; I = 0%) and procedural success (80.4% versus 86.2%; OR, 0.61; 95% CI, 0.53-0.70; P < .00001; I = 10%); a higher risk of all-cause mortality (OR, 2.95; 95% CI, 1.56-5.57; P = 0.0008; I = 0%), MI (OR, 2.30; 95% CI, 1.40-3.80; P = .001; I = 5%), and coronary perforation (OR, 2.16; 95% CI, 1.51-3.08; P < 0.0001; I = 52%). On the other hand, the risk of pericardial tamponade (OR, 0.42; 95% CI, 0.15-1.18; P = .10; I = 21%), major bleeding (OR, 1.51; 95% CI, 0.90-2.53; P = .11; I = 0%), vascular access complication (OR, 1.50; 95% CI, 0.93-2.41; P = .10; I = 0%), and emergency CABG (OR, 0.99; 95% CI, 0.25-3.91; P = .99; I = 0%) was similar in both groups.Compared to nCABG patients, pCABG patients had lower CTO PCI success rates, higher rates of in-hospital mortality, MI, and coronary perforation, and similar risk of pericardial tamponade and vascular complication rates.

Abstract
Introduction: Coronary chronic total occlusions (CTO) represent a challenging subset in interventional cardiology.Areas covered: During the last decade, improvements in materials, techniques, and meticulous pre-procedural lesion assessment have increased the success rate in CTO lesions. Several scores have been developed to address overall lesion evaluation and help select the most appropriate treatment strategy. In addition, specific algorithms such as the hybrid algorithm have been introduced to provide a framework for CTO operators and a rapid management of the various challenging aspects of the procedure. The hybrid approach requires operator's ability to switch from one treatment strategy to another when the first one appears to be unsuccessful. Adequate training and operators' experience remain crucial to improve the likelihood of success.Expert opinion: The aim of this review is to provide insights and guidance for operators on current approaches for treatment of CTO and complication management.
