Project description:Background Given that percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) is indicated primarily for symptom relief, identifying patients most likely to benefit is critically important for patient selection and shared decision-making. Therefore, we identified factors associated with residual angina frequency after CTO PCI and developed a model to predict postprocedure anginal burden. Methods and Results Among patients in the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures) registry, we evaluated the association between patient characteristics and residual angina frequency at 6 months, as assessed by the Seattle Angina Questionnaire Angina Frequency Scale. We then constructed a prediction model for angina status after CTO PCI using ordinal regression. Among 901 patients undergoing CTO PCI, 28% had no angina, 31% had monthly angina, 30% had weekly angina, and 12% had daily angina at baseline. Six months later, 53% of patients had a ≥20-point increase in Seattle Angina Questionnaire Angina Frequency Scale score. The final model to predict residual angina after CTO PCI included baseline angina frequency, baseline nitroglycerin use frequency, dyspnea symptoms, depressive symptoms, number of antianginal medications, PCI indication, and presence of multiple CTO lesions and had a C index of 0.78. Baseline angina frequency and nitroglycerin use frequency explained 71% of the predictive power of the model, and the relationship between model components and angina improvement at 6 months varied by baseline angina status. Conclusions A 7-component OPEN-AP (OPEN-CTO Angina Prediction) score can predict angina improvement and residual angina after CTO PCI using variables commonly available before intervention. These findings have implications for appropriate patient selection and counseling for CTO PCI.

Project description:Administration of a large amount of contrast volume during chronic total occlusion (CTO) percutaneous coronary intervention (PCI) may lead to contrast-induced nephropathy.We examined the association of clinical, angiographic and procedural variables with contrast volume administered during 1330 CTO-PCI procedures performed at 12 experienced United States centers.Technical and procedural success was 90% and 88%, respectively, and mean contrast volume was 289 ± 138 mL. Approximately 33% of patients received >320 mL of contrast (high contrast utilization group). On univariable analysis, male gender (P=.01), smoking (P=.01), prior coronary artery bypass graft surgery (P=.04), moderate or severe calcification (P=.01), moderate or severe tortuosity (P=.04), proximal cap ambiguity (P=.01), distal cap at a bifurcation (P<.001), side branch at the proximal cap (P<.001), blunt/no stump (P=.01), occlusion length (P<.001), higher J-CTO score (P=.02), use of antegrade dissection and reentry or retrograde approach (P<.001), ad hoc CTO-PCI (P=.04), dual arterial access (P<.001), and 8 Fr guide catheters (P<.001) were associated with higher contrast volume; conversely, diabetes mellitus (P=.01) and in-stent restenosis (P=.01) were associated with lower contrast volume. On multivariable analysis, moderate/severe calcification (P=.04), distal cap at a bifurcation (P<.001), ad hoc CTO-PCI (P<.001), dual arterial access (P=.01), 8 Fr guide catheters (P=.02), and use of antegrade dissection/reentry or the retrograde approach (P<.001) were independently associated with higher contrast use, whereas diabetes (P=.02), larger target vessel diameter (P=.03), and presence of "interventional" collaterals (P<.001) were associated with lower contrast utilization.Several baseline clinical, angiographic, and procedural characteristics are associated with higher contrast volume administration during CTO-PCI.

Project description:Intravascular imaging can facilitate chronic total occlusion (CTO) percutaneous coronary intervention.We examined the frequency of use and outcomes of intravascular imaging among 619 CTO percutaneous coronary interventions performed between 2012 and 2015 at 7 US centers. Mean age was 65.4±10 years and 85% of the patients were men. Intravascular imaging was used in 38%: intravascular ultrasound in 36%, optical coherence tomography in 3%, and both in 1.45%. Intravascular imaging was used for stent sizing (26.3%), stent optimization (38.0%), and CTO crossing (35.7%, antegrade in 27.9%, and retrograde in 7.8%). Intravascular imaging to facilitate crossing was used more frequently in lesions with proximal cap ambiguity (49% versus 26%, P<0.0001) and with retrograde as compared with antegrade-only cases (67% versus 31%, P<0.0001). Despite higher complexity (Japanese CTO score: 2.86±1.19 versus 2.43±1.19, P=0.001), cases in which imaging was used for crossing had similar technical and procedural success (92.8% versus 89.6%, P=0.302 and 90.1% versus 88.3%, P=0.588, respectively) and similar incidence of major cardiac adverse events (2.7% versus 3.2%, P=0.772). Use of intravascular imaging was associated with longer procedure (192 minutes [interquartile range 130, 255] versus 131 minutes [90, 192], P<0.0001) and fluoroscopy (71 minutes [44, 93] versus 39 minutes [25, 69], P<0.0001) time.Intravascular imaging is frequently performed during CTO percutaneous coronary intervention both for crossing and for stent selection/optimization. Despite its use in more complex lesion subsets, intravascular imaging was associated with similar rates of technical and procedural success for CTO percutaneous coronary intervention.URL: http://www.clinicaltrials.gov.

Project description:High success rates are achievable for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using the hybrid approach, but periprocedural complications remain of concern. Although scores estimating success and efficiency in CTO PCI have been developed, there is currently no available score for estimation of the risk for periprocedural complications. We sought to develop a scoring tool for prediction of periprocedural complications during CTO PCI. We analyzed data from 1569 CTO PCIs in the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS CTO) using a derivation and validation sampling ratio of 2:1. Variables independently associated with periprocedural complications in multivariable analysis in the derivation set were assigned points based on their respective odds ratios. Forty-four (2.8%) patients experienced complications. Three factors were independent predictors of complications and were included in the score: patient age >65 years, +3 points (odds ratio, OR=4.85, CI 1.82-16.77); lesion length ≥23 mm, +2 points (OR=3.22, CI 1.08-13.89); and use of the retrograde approach +1 point (OR=2.41, CI 1.04-6.05). The resulting score showed good calibration and discriminatory capacity in the derivation (Hosmer-Lemeshow χ2 6.271, P=0.281, receiver-operating characteristic [ROC] area=0.758) and validation (Hosmer-Lemeshow χ2 4.551, P=0.473, ROC area=0.793) sets. Score values of 0 to 2, 3 to 4, and ≥5 were defined as low, intermediate, and high risk of complications (derivation cohort 0.4%, 1.8%, 6.5%, P<0.001; validation cohort 0.0%, 2.5%, 6.8%, P<0.001). The PROGRESS CTO complication score is a useful tool for prediction of periprocedural complications in CTO PCI. URL: http://www.clinicaltrials.gov. Unique identifier: NCT02061436.

Project description:ObjectivesTo analyse the feasibility, safety and procedural outcomes of percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) through retrograde approach using single catheter.MethodsOur study was a retrospective observational study that enrolled patients who underwent retrograde CTO PCI using a single catheter between June 2016 and February 2020. Clinical success was defined as successful completion of CTO PCI without associated in-hospital major clinical complications like death, myocardial infarction, stroke or urgent revascularisation. Technical success was defined as successful completion of CTO PCI using single catheter and minimum diameter stenosis of <30% with thrombolysis in myocardial infarction (TIMI) flow grade 3, without significant side branch occlusion, flow-limiting dissection, distal embolization, or angiographic thrombus.ResultsTotally 102 patients underwent retrograde CTO PCI during the study period. Out of which, 15 cases were attempted using single catheter. Mean age of the population was 59.1 ± 8.9 years (males: 86.7%) and the left ventricular ejection fraction (LVEF) was (61% ± 9.1%). Mean number of diseased arteries was 2.1 ± 0.7, length of the CTO was 25.5 ± 7.4 mm and J-CTO score was 2.3 ± 0.7. We achieved a technical success rate of 73.3% using single catheter, and the overall clinical success (Including single catheter and ping pong) was obtained in 86.7% cases. One patient (6.7%) developed cardiac tamponade and none of study population required dialysis for contrast induced acute kidney injury (CI-AKI) CONCLUSIONS: Retrograde CTO PCI using single catheter is a technically challenging procedure when compared with other CTO PCI. Our study demonstrated acceptable outcomes which is comparable to other antegrade and retrograde CTO PCI registries.

Project description:BackgroundWe sought to determine the effect of lesion age on procedural techniques and outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI).MethodsWe examined the characteristics and outcomes of 394 CTO PCIs with data on lesion age, performed between 2012 and 2016 at 11 experienced US centres.ResultsMean patient age was 66 ± 10 years and 85.6% of the patients were men. Overall technical and procedural success rates were 90.1% and 87.5%, respectively. A major adverse cardiovascular event (MACE) occurred in 16 patients (4.1%). Mean and median lesion ages were 43 ± 62 months and 12 months (interquartile range, 3-64 months), respectively. Patients were stratified into tertiles according to lesion age (3-5, 5-36.3, and > 36.3 months). Older lesion age was associated with older patient age (68 ± 8 vs 65 ± 10 vs 64 ± 11 years; P = 0.009), previous coronary artery bypass grafting (62% vs 42% vs 30%; P < 0.001), and moderate/severe calcification (75% vs 53% vs 59%; P = 0.001). Older lesions more often required use of the retrograde approach and antegrade dissection/re-entry for successful lesion crossing. There was no difference in technical (87.8% vs 89.6% vs 93.0%; P = 0.37) or procedural (86.3% vs 87.4% vs 89.0%; P = 0.80) success, or the incidence of MACE (3.1% vs 3.0% vs 6.3%; P = 0.31) for older vs younger occlusions.ConclusionsOlder CTO lesions exhibit angiographic complexity and more frequently necessitate the retrograde approach or antegrade dissection/re-entry. Older CTOs can be recanalized with high technical and procedural success and acceptable MACE rates. Lesion age appears unlikely to be a significant determinant of CTO PCI success.

Project description:BackgroundWe assessed efficacy and safety of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using antegrade dissection re-entry (ADR).MethodsWe examined outcomes of ADR among 1313 CTO PCIs performed at 11 US centers between 2012-2015.Results84.1% of patients were men. Prevalence of prior coronary artery bypass graft surgery was 34.3%. Overall technical and procedural success were 90.1% and 88.7%, respectively. In-hospital major adverse cardiovascular events (MACE) occurred in 31 patients (2.4%). ADR was used in 458 cases (34.9%), and was the first strategy in 169 cases (12.9%). ADR cases were angiographically more complex than non-ADR cases (mean J-CTO score: 2.8±1.2 vs. 2.4±1.2, p<0.001). ADR was performed using the CrossBoss catheter in 246 of 458 (53.7%) and the Stingray system in 251 ADR cases (54.8%). Compared with non-ADR cases, ADR cases had lower technical (86.9% vs. 91.8%, p=0.005) and procedural success (85.0% vs. 90.7%, p=0.002), but similar risk for MACE (2.9% vs. 2.2%, p=0.42). ADR was associated with longer procedure and fluoroscopy time, and higher patient air kerma dose and contrast volume (all p<0.001). After excluding retrograde cases, ADR and antegrade wire escalation (AWE) had similar technical success (92.7% vs. 94.2%, p=0.43), procedural success (91.8% vs. 94.1%, p=0.23), and MACE (2.1% vs. 0.6%, p=0.12).ConclusionsADR is used relatively frequently in contemporary CTO PCI, especially for challenging lesions and after failure of other strategies. ADR is associated with similar success rates and risk for complications as compared with AWE, and is important for achieving high procedural success.

Project description:BackgroundThe field of CTO PCI is expanding, but successful and safe percutaneous coronary intervention (PCI) of coronary chronic total occlusions (CTO) requires a substantial resource and experience investment. We aimed to assess temporal trends in strategies and outcomes of 2 dedicated programs for CTO PCI.MethodsBetween 2011 and 2020, 920 CTO PCI procedures were prospectively included at 2 referral centres in Belgium. Temporal trends were assessed, and logistic regression models were built to identify predictors of outcome.ResultsDespite an increase in lesion complexity (the J-CTO score increased from 1.3 in year 1 to 1.7-2.0 in years 8-9, p < 0.001), technical success improved from 70.0% to 85.6% in year 9 (p value for trend <0.001). We observed the most significant improvement starting at years 3-4 (OR 2.3 in year 4 versus year 1, p=0.018). Together with an increase in success rates and lesions complexity, there was an increase in the use of dual injections, retrograde approaches, the number of balloons and stents, and the use of microcatheters. Conversely, there was a decrease in large bore access, an increase in radial approach, and a shift towards contemporary dissection/reentry techniques. This strategy resulted in a stable major complication rate of 4.7% (p value for trend 0.33). The rate of coronary procedure-related myocardial injury was high (71.0%) and was associated with the use of more intracoronary devices.ConclusionsThree to four years after initiation of a dedicated CTO PCI program with 50 CTO PCIs per year, consistent high technical success and low complication rates are achieved using contemporary strategies.

Project description:BackgroundPatients with chronic total coronary occlusions (CTO) are at increased risk for poor clinical outcomes. We aimed to determine the incidence of CTO percutaneous coronary intervention (PCI) and to identify CTO patients at risk for cardiac events in the nationwide Netherlands Heart Registration (NHR).MethodsWe included all PCI procedures with ≥1 CTO registered in the NHR from January 2015 to December 2018, excluding acute interventions. We used multivariable logistic regression of baseline characteristics to calculate the risk for events as odds ratios (OR) with 95% confidence intervals (CI).ResultsOf the PCIs performed during the study period, 6.3% (8,343/133,042) were for CTOs, with the percentage increasing significantly over time from 5.9% in 2015 to 6.6% in 2018 (p < 0.001). Coronary artery bypass grafting <24 h was carried out in 0.3%, and the only significant predictor was diabetes mellitus (OR 2.97, 95% CI 1.04-8.49, p = 0.042). Myocardial infarction (MI) <30 days occurred in 0.5%, and renal insufficiency (i.e. estimated glomerular filtration rate <30 ml/min per 1.73 m2) was identified as an independent predictor (OR 4.70, 95% CI 1.07-20.61, p = 0.040). Among patients undergoing CTO-PCI, 1‑year mortality was 3.7%, and independent predictors included renal insufficiency (OR 5.59, 95% CI 3.25-9.59, p < 0.001), left ventricular ejection fraction <30% (OR 3.43, 95% CI 2.00-5.90, p < 0.001), previous MI (OR 1.62, 95% CI 1.14-2.31, p = 0.007) and age (OR 1.06 per year increment, 95% CI 1.04-1.07, p < 0.001). Target-vessel revascularisation <1 year occurred in 11.3%.ConclusionCTO-PCI is still infrequently performed in the Netherlands. The most important predictor of mortality after CTO-PCI was renal insufficiency. Identification of patients at risk may help improve the prognosis of CTO patients in the future.
