Abstract
Percutaneous treatment of coronary chronic total occlusions (CTO) has advanced greatly since its advent in the late 1970s through the development of dedicated wires and microcatheters, the improved skills of highly experienced operators and the adoption of new sophisticated strategies to guide procedural planning. The contemporary procedural success rate is 80-90% with a reduction in complications. Although there has been no improvement in prognosis in randomised trials to date, they, and other controlled registries of thousands of patients, confirm the pivotal role of CTO recanalisation in the treatment of angina and dyspnoea and an improvement in quality of life. Despite this evidence, CTO recanalisation is grossly underutilised. This review reports a detailed overview of the history, indications and treatment strategies for CTO recanalisation and hopes to increase interest among new, and especially young, operators in this demanding, rapidly evolving field of interventional cardiology.

Abstract
In 2009, rapamycin was reported to increase the lifespan of mice when implemented later in life. This observation resulted in a sea-change in how researchers viewed aging. This was the first evidence that a pharmacological agent could have an impact on aging when administered later in life, i.e., an intervention that did not have to be implemented early in life before the negative impact of aging. Over the past decade, there has been an explosion in the number of reports studying the effect of rapamycin on various diseases, physiological functions, and biochemical processes in mice. In this review, we focus on those areas in which there is strong evidence for rapamycin's effect on aging and age-related diseases in mice, e.g., lifespan, cardiac disease/function, central nervous system, immune system, and cell senescence. We conclude that it is time that pre-clinical studies be focused on taking rapamycin to the clinic, e.g., as a potential treatment for Alzheimer's disease.

Elastic stent recoil in coronary total occlusions: Comparison of durable-polymer zotarolimus eluting stent and ultrathin strut bioabsorbable-polymer sirolimus eluting stent. Catheter Cardiovasc Interv 2021; 99:88-97. [PMID: 33961730 PMCID: PMC9543547 DOI: 10.1002/ccd.29739] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 03/26/2021] [Accepted: 04/15/2021] [Indexed: 11/09/2022]
Abstract
Objectives To compare stent recoil (SR) of the thin‐strut durable‐polymer Zotarolimus‐eluting stent (dp‐ZES) and the ultrathin‐strut bioabsorbable‐polymer Sirolimus‐eluting stent (bp‐SES) in chronic total occlusions (CTOs) and to investigate the predictors of high SR in CTOs. Background Newer ultrathin drug eluting stent might be associated with lower radial force and higher elastic recoil due to the thinner strut design, possibly impacting on the rate of in‐stent restenosis and thrombosis. Methods Between January 2017 and November 2019, consecutive patients with CTOs undergoing percutaneous coronary intervention were evaluated. Only patients treated with dp‐ZES or bp‐SES were included and stratified accordingly. Quantitative coronary angiography analysis was used to assess absolute SR, relative SR, absolute focal SR, relative focal SR, high absolute, and high relative focal SR. Results A total of 128 lesions (67 treated with dp‐ZES and 61 with bp‐SES) in 123 patients were analyzed. Between bp‐SES and dp‐ZES no differences were found in absolute SR (p = .188), relative SR (p = .138), absolute focal SR (p = .069), and relative focal SR (p = .064). High absolute and high relative focal SR occurred more frequently in bp‐SES than in dp‐ZES (p = .004 and p = .015). Bp‐SES was a predictor of high absolute focal SR (Odds ratio [OR] 3.29, 95% confidence interval [CI] 1.50–7.22, p = .003]. High‐pressure postdilation and bp‐SES were predictors of high relative focal SR (OR 2.22, 95% CI 1.01–4.86, p = .047; OR 2.74, 95% CI 1.24–6.02, p = .012, respectively). Conclusions Both stents showed an overall low SR. However, ultra‐thin strut bp‐SES was a predictor of high absolute and high relative focal SR.

Comparison of Clinical Outcomes Between Second-and First-Generation Drug-Eluting Stents in Patients With Chronic Total Occlusion Lesion: A Meta-Analysis. Front Cardiovasc Med 2021; 8:598046. [PMID: 33959639 PMCID: PMC8096061 DOI: 10.3389/fcvm.2021.598046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2020] [Accepted: 03/22/2021] [Indexed: 11/15/2022] Open
Abstract
Background and Objectives: The second-generation drug-eluting stents have been used to treat chronic total occlusion lesion. However, there is limited evidence of the clinical outcomes that whether the second-generation drug-eluting stents is superior to first-generation ones in patients with chronic total occlusion lesion undergoing percutaneous coronary intervention. The study aimed to compare the differences in clinical outcomes between the two generations drug-eluting stents in patients with those by a meta-analysis. Methods: PubMed, Embase, the Cochrane library and Web of science databases were systemically searched before March, 2021. Randomized controlled trials and observational studies were included to compare the second-generation drug-eluting stents with the first-generation ones in patients with chronic total occlusion lesion undergoing percutaneous coronary intervention. The clinical outcomes were major adverse cardiac events (MACE), target vessel revascularization, myocardial infarction, all-cause death. Fixed effects models were used to calculate the odds ratio (OR) and 95% confidence interval (CI) of each clinical outcome. Sensitivity analysis was performed to detect potential sources of heterogeneity. Subgroup analyses were used to assess the differential effects. Results: The meta-analysis included eight studies involving 4,583 patients with chronic total occlusion lesion undergoing percutaneous coronary intervention. Pooled analysis showed that the incidence of MACE (OR = 0.68, 95%CI 0.54–0.85, P = 0.0008), target vessel revascularization (OR = 0.70, 95%CI 0.54–0.91, P = 0.007), and myocardial infarction (OR = 0.58, 95%CI 0.37–0.93, P = 0.02) were lower in the second-generation drug-eluting stents compared with the first-generation ones. However, there was not difference in all-cause deaths between two drug-eluting stents (OR = 0.67, 95%CI 0.45–1.01, P = 0.05). Conclusions: The second-generation drug-eluting stents are associated with lower MACE, target vessel revascularization, and myocardial infarction compared with the first-generation ones in patients with chronic total occlusion lesion undergoing percutaneous coronary intervention. The results of this study can provide a reference for the selection of stents in patients with chronic total occlusion lesion. Further randomized controlled trials are needed to verify that the second-generation drug-eluting stents is superior to the first-generation ones in patients with chronic total occlusion (Registered by PROSPERO, CRD42020158406).

Abstract
Background: The objective of this review is to provide a practical update on endpoint selection for noninferiority (NI) studies in percutaneous coronary intervention studies. Methods: A PubMed search was conducted for predefined terms to explore the use of NI designs and intrapatient comparisons to determine their current importance. Sample size calculations for the most frequently used endpoints with NI hypotheses were done to increase statistical awareness. Results: Reported NI trials, with the most frequently chosen clinical endpoint of major adverse cardiac events (MACE), had NI margins ranging from 1.66% to 5.00%, resulting in patient populations of 400–1500 per treatment group. Clinical study endpoints comprising of MACE complemented with rates of bleeding complications and stent thrombosis (ST) are suggested to conduct a statistically and clinically meaningful NI trial. Study designs with surrogate endpoints amenable to intrapatient randomizations, are a very attractive option to reduce the number of necessary patients by about half. Comparative clinical endpoint studies with MACE and ST/bleeding rates to study a shortened dual antiplatelet therapy (DAPT) in coronary stent trials are feasible, whereas ST as the sole primary endpoint is not useful. Conclusions: Expanded composite clinical endpoints (MACE complemented by ST and bleeding rates and intrapatient randomization for selected surrogate endpoints) may be suitable tools to meet future needs in device approval, recertification and reimbursement.

Occurrence and predictive factors of restenosis in coronary heart disease patients underwent sirolimus-eluting stent implantation. Ir J Med Sci 2020; 189:907-915.

Abstract
BACKGROUND This study aimed to investigate the occurrence and predictive factors of restenosis in coronary heart disease (CHD) patients underwent percutaneous coronary intervention (PCI) with sirolimus-eluting stent (SES). METHODS Demographic data, clinical features, and laboratory tests of 398 CHD patients underwent PCI with SES were retrospectively reviewed. Coronary angiography was performed to evaluate coronary stenosis before PCI and in-stent restenosis at 1-year follow-up. RESULTS There were 37 (9.3%) patients suffered restenosis, but 361 (90.7%) patients did not develop restenosis at 1-year follow-up. Demographic characteristic (age), cardiovascular risk factors (hypertension and hyperuricemia), biochemical indexes (fasting blood-glucose, total cholesterol, low density lipoprotein cholesterol (LDL-C) and high-sensitivity C-reactive protein (HsCRP)), cardiac function index (cardiac troponin I), lesion features (multivessel artery lesions, target lesion at left circumflex artery (LCX), two target lesions and length of target lesion), and operation procedure (length of stent) were correlated with higher restenosis risk. Moreover, age, hypertension, diabetes mellitus, LDL-C, HsCRP, and target lesion at LCX were independent predictive factors for raised restenosis risk. Based on these independent predictive factors, we established a restenosis risk prediction model, and receiver-operating characteristic curves displayed that this model exhibited an excellent predictive value for higher restenosis risk (areas under the curve 0.953 (95% CI 0.926-0.981)). CONCLUSION Our findings provide a new insight into the prediction for restenosis in CHD patients underwent PCI with SES.

Abstract
BACKGROUND The RESOLUTE-DIABETES CHINA study was specifically designed to investigate the safety and efficacy of Resolute zotarolimus-eluting stents (ZES; Medtronic, Santa Rosa, CA, USA) in the treatment of diabetic coronary lesions in the Chinese population. METHODS In all, 945 patients with de novo native coronary lesions and type 2 diabetes mellitus were recruited at 32 cardiac centers across the Chinese mainland and were implanted with Resolute ZES. The primary endpoint was target vessel failure (TVF); secondary endpoints were clinical outcomes, namely all-cause death, stroke, bleeding, target lesion revascularization (TLR), target vessel revascularization (TVR), non-TVR, and stent thrombosis (ST). The follow-up period for all endpoints was 12 months after the procedure. RESULTS In all, 933 patients (98.73%) had clinical follow-up at 12 months. The rate of TVF was 11.60%, whereas the rate of occurrence of secondary endpoints was 5.47%, with four patients (0.43%) having subacute or late ST. There were no significant differences in TVF rates comparing patients with different HbA1c levels or receiving different glucose control treatments (all P > 0.05). Patients with multivessel lesions had higher TVF rates (95% confidence intervals) than those with single-vessel lesions (16.76% [12.10%-22.97%) vs 9.72% [7.79%-12.11%], respectively; P = 0.006). There were no significant differences in TVF rates in patients with or without small vessels, bifurcated lesions, or chronic total occlusions (all P > 0.05). [Correction added on 17 January 2019, after first online publication: in the second sentence of Results section, "TLF" was changed to "TVF".]. CONCLUSIONS Resolute ZES may perform well in the Chinese diabetic population, especially in those with poor glucose control, complex lesions, and certain unfavorable clinical features. Further studies are needed to determine why ZES perform well in this population.

Abstract
BACKGROUND The aim of this study was to identify the prognostic predictors for the worse clinical outcomes after a successful chronic total occlusion (CTO) intervention with drug-eluting stents. PATIENTS AND RESULTS A total of 2334 patients in the multicenter Korean CTO registry who underwent a successful CTO intervention with drug-eluting stents (first generation, 1367, new generation, 967) were enrolled. The primary endpoint was the composite of cardiac death, myocardial infarction, and stent thrombosis.The cumulative incidence of the primary endpoint was 2.5% (median follow-up duration: 22 months). In multivariate analysis, age above 65 years [hazard ratio (HR)=1.769, 95% confidence interval (CI)=1.025-3.052, P=0.041], heart failure (HR=4.242, 95% CI=2.335-7.705, P<0.001), and diabetes (HR=1.773, 95% CI=1.043-3.012, P=0.034) were the significant predictors. The cumulative incidence of the primary endpoint was significantly higher in patients with three risk factors (19.1%) than in those with one (2.2%) or two (3.0%) risk factors (P=0.001). The cumulative target-vessel revascularization rate was 8.4%, with the significant predictors being a diffuse long lesion (HR=1.626, 95% CI=1.129-2.340, P=0.009) and at least three implanted stents (HR=1.964, 95% CI=1.301-2.965, P=0.001). CONCLUSION Clinical parameters such as age, diabetes, and heart failure were independent predictors of the composite of cardiac death, myocardial infarction, and stent thrombosis, whereas angiographic or procedural parameters such as lesion length and number of implanted stents were predictors of target-vessel revascularization. Clinical outcomes after CTO intervention were worse in patients with multiple risk factors.

Abstract
OBJECTIVES Data on bioresorbable vascular scaffolds for recanalization of chronic total occlusions (CTOs) are limited. We compared the bioresorbable scaffold Absorb with everolimus-eluting stents for the treatment of true CTO. METHODS After recanalization of CTO, 15 lesions treated with the bioresorbable scaffold Absorb were matched with 15 lesions receiving everolimus-eluting stent (EES) (http://www.clinicaltrials.gov NCT02162082). Match criteria were presence of diabetes mellitus, total device length and maximal device diameter. Angiographic follow-up was scheduled after 9 months and clinical follow-up after 12 months. Dual antiplatelet therapy was administered for 12 months. Quantitative coronary analysis was carried out before and after implantation and at angiographic follow-up. All lesions were predilated. The Absorb scaffolds and drug-eluting stents were carefully placed and postdilatated with high-pressure balloons. Patients received dual antiplatelet therapy for 12 months. The baseline characteristics were similar between both the groups. The mean scaffold length was 81.7±29.1 versus 79.3±27.4 mm for the mean stent length (P=0.82). In-device late lumen loss at the 9-month follow-up was 0.38±0.47 versus 0.46±0.60 mm (P=0.69). The device-oriented composite endpoint was similar in both groups, with 6.7% in the Absorb-group versus 13.3% in the EES group because of target lesion revascularization (P=0.54). CONCLUSION In CTOs, the use of a bioresorbable scaffold Absorb after recanalization showed similar 9-month angiographic and 12-month clinical results compared with an EES with 12 months of dual antiplatelet therapy.

Abstract
BACKGROUND Limited data are available regarding the long-term clinical outcomes of second-generation drug-eluting stents (DES) versus first-generation DES in patients with coronary chronic total occlusion (CTO) who undergo percutaneous coronary intervention (PCI). The aim of this study was to compare the clinical outcomes of second-generation DES with those of first-generation DES for the treatment of CTO. METHODS AND RESULTS Between March 2003 and February 2012, 1,006 consecutive patients with CTO who underwent successful PCI using either first-generation DES (n = 557) or second-generation DES (n = 449) were enrolled in a multicenter, observational registry. Propensity-score matching was also performed. The primary outcome was cardiac death over a 2-year follow-up period. No significant differences were observed between the two groups regarding the incidence of cardiac death (first-generation DES versus second-generation DES; 2.5% vs 2.0%; hazard ratio [HR]: 0.86; 95% confidence interval [CI]: 0.37 to 1.98; p = 0.72) or major adverse cardiac events (MACE, 11.8% vs 11.4%; HR: 1.00; 95% CI: 0.67 to 1.50; p = 0.99). After propensity score matching, the incidences of cardiac death (HR: 0.86; 95% CI: 0.35 to 2.06; p = 0.86) and MACE (HR: 0.93; 95% CI: 0.63 to 1.37; p = 0.71) were still similar in both groups. Furthermore, no significant differences were observed between sirolimus-eluting, paclitaxel-eluting, zotarolimus-eluting, and everolimus-eluting stents regarding the incidence of cardiac death or MACE. CONCLUSION This study shows that the efficacy of second-generation DES is comparable to that of first-generation DES for treatment of CTO over 2 years of follow-up.

One-Year Results of Bioresorbable Vascular Scaffolds for Coronary Chronic Total Occlusions. Am J Cardiol 2016; 117:906-17. [PMID: 26874547 DOI: 10.1016/j.amjcard.2015.12.025] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2015] [Revised: 12/18/2015] [Accepted: 12/18/2015] [Indexed: 11/17/2022]
Abstract
The potential of bioresorbable vascular scaffold (BVS) technology has been demonstrated in first-in-man studies with up to 5-year follow-up. This study sought to investigate the 1-year outcomes of the BVS, for the treatment of chronic total occlusions (CTOs), using various imaging techniques. Thirty-five true CTO lesions treated with BVS were included in this prospective study. Scaffolds were deployed after mandatory predilation and intravascular ultrasound analysis. Optical coherence tomography was performed after BVS implantation and at 10 to 12 months. Multislice computed tomography was performed at baseline and at 6 to 8 months. Mean patient age was 61 ± 10 years. The most frequent vessel treated was the right coronary artery (46%). Lesions were classified as intermediate (49%) or difficult/very difficult (26%) according to the Japanese CTO complexity score. Predilation was performed in 100% of lesions, using cutting balloons in 71% of these. The total scaffold length implanted per lesion was of 52 ± 23 mm. All scaffolds were delivered and deployed successfully. Postdilation was undertaken in 63%. By multislice computed tomography at 6 months, we observed 2 cases of asymptomatic scaffold restenosis, subsequently confirmed by angiography. At 12 months, no scaffold thrombosis or major adverse cardiac events were reported. The optical coherence tomography at follow-up showed that 94% of struts were well apposed and covered (5% of uncovered struts and 1% of nonapposed struts), and only 0.6% of struts were nonapposed and uncovered. In conclusion, 1-year results suggest that BVS for CTO is associated with excellent clinical and imaging outcomes. Accurate percutaneous coronary BVS technique might have enabled these promising results.

Abstract
BACKGROUND The performance of contemporary second-generation drug-eluting stents (DESs) for percutaneous chronic total occlusion (CTO) intervention is not well established. The present study compared the efficacy and safety outcomes of second-generation DESs with those of first-generation DESs in CTO-percutaneous coronary intervention (PCI). METHODS This retrospective analysis included 1049 consecutive CTO patients who underwent successful DES implantation (first-generation; 487 vs. second-generation; 562 patients) between March 2003 and August 2014. The primary endpoint was the composite of all-cause death, Q-wave myocardial infarction (MI), or target-vessel revascularization (TVR). RESULTS During a follow-up of 3 years, the primary endpoint incidence was 10.1% for second- and 7.7% for first-generation DES (p=0.30). After multivariable adjustment, there was no significant difference between these groups in terms of the risk of composite of death, Q-wave MI, or TVR (Hazard ratio [HR] 1.42, 95% confidence interval [CI] 0.88-2.28, p=0.15) nor in the individual risks of death (adjusted HR 1.33, 95% CI 0.69-2.56, p=0.39), Q-wave MI (adjusted HR 1.15, 95% CI 0.30-4.47, p=0.84) and TVR (adjusted HR 1.06, 95% CI 0.52-2.15, p=0.87). The incidence of definite/probable stent thrombosis was relatively low (0.5% vs.0.9%, p=0.17) throughout the follow-up period. CONCLUSION The 3-year clinical outcomes of patients treated with second-generation DESs are comparable to those treated with first-generation DESs for CTO-PCI.

Intravascular Ultrasound and Angiographic Predictors of In-Stent Restenosis of Chronic Total Occlusion Lesions. PLoS One 2015; 10:e0140421.

Abstract
Despite the benefits of successful percutaneous coronary interventions (PCIs) for chronic total occlusion (CTO) lesions, PCIs of CTO lesions still carry a high rate of adverse events, including in-stent restenosis (ISR). Because previous reports have not specifically investigated the intravascular ultrasound (IVUS) predictors of ISR in CTO lesions, we focused on these predictors. We included 126 patients who underwent successful PCIs, using drug-eluting stents, and post-PCI IVUS of CTO lesions. Patient and lesion characteristics were analyzed to elucidate the ISR predictors. In each lesion, an average of 1.7 ± 0.7 (mean length, 46.4 ± 20.3 mm) stents were used. At 9 months follow-up, 14 (11%) patients demonstrated ISR, and 8 (6.3%) underwent target lesion revascularization. Multivariate logistic regression analysis showed that the independent predictors of ISR were the post-PCI minimal luminal diameter (MLD) and the stent expansion ratio (SER; minimal stent cross-sectional area (CSA) over the nominal CSA of the implanted stent), measured using quantitative coronary angiography (QCA) and IVUS, respectively. A receiver operating characteristic analysis indicated that the best post-PCI MLD and SER cut-off values for predicting ISR were 2.4 mm (area under the curve [AUC], 0.762; 95% confidence interval (CI), 0.639–0.885) and 70% (AUC, 0.714; 95% CI, 0.577–0.852), respectively. Lesions with post-PCI MLD and SER values less than these threshold values were at a higher risk of ISR, with an odds ratio of 23.3 (95% CI, 2.74–198.08), compared with lesions having larger MLD and SER values. Thus, the potential predictors of ISR, after PCI of CTO lesions, are the post-PCI MLD and SER values. The ISR rate was highest in lesions with a post-PCI MLD ≤2.4 mm and an SER ≤70%.

Abstract
Clinical success of coronary drug-eluting stents (DES) is hampered by simultaneous reduction of smooth muscle cell (HCASMC) and endothelial cell proliferation due to unspecific cytotoxicity of currently used compounds. Previous in vitro data showing SMC-specific inhibition of proliferation suggested that statins may be suitable candidates for DES. It was aim of this study to further investigate statins as DES drug candidates to identify mechanisms contributing to their cell-selectivity. In vitro proliferation assays comparing the influence of various statins on HCASMC and endothelial cells confirmed that atorvastatin exhibits HCASMC-specificity. Due to similar expression levels of the drug target HMG-CoA reductase in both cell types, cellular accumulation of atorvastatin was assessed, revealing enhanced uptake in HCASMC most likely driven by significant expression of OATP2B1, a known uptake transporter for atorvastatin. In accordance with the finding that endogenous OATP2B1 influenced cellular accumulation in HCASMC we used this transporter as a tool to identify teniposide as new DES candidate drug with HCASMC-specific effects. We describe OATP2B1 as a determinant of pharmacokinetics in the coronary artery. Indeed, endogenously expressed OATP2B1 significantly influences the uptake of substrate drugs, thereby governing cell specificity. Screening of candidate drugs for interaction with OATP2B1 may be used to promote SMC-specificity.

Abstract
Everolimus-eluting bioresorbable vascular scaffold (BVS) implantation in chronic total occlusion (CTO) could provide theoretical advantages at follow-up compared with metallic stents. This study aimed to assess the feasibility of BVS use for the percutaneous treatment of CTO by analyzing clinical outcomes and patency at midterm follow-up. From February 2013 to June 2014, 42 patients with 46 CTOs were treated by BVS implantation. Once the guidewire reached the distal lumen, all the occluded segments were predilated. Postdilation was performed in all patients. A multislice computed tomography was scheduled for all patients at 6 months. The mean age was 58 ± 9 years, 41 (98%) were men and 14 (33%) diabetic. The target vessel was predominantly the left anterior descending artery (22, 48%). According to the Japanese-CTO score, 21 CTOs (46%) were difficult or very difficult. Most cases were treated with an anterograde strategy (34 lesions, 74%). A hybrid procedure with a drug-eluting stent at the distal segment was the applied treatment in 7 CTOs (15%). The mean scaffold length was 43 ± 21 mm. Technical success was achieved in 45 lesions (98%), and 1 patient (2.4%) presented a non-Q periprocedural myocardial infarction. Re-evaluation was obtained in all patients at 6 ± 1 months. Two re-occlusions and a focal restenosis were identified. After 13 ± 5 months of follow-up, there were 2 repeat revascularizations (4.8%). Neither death nor myocardial infarction was documented. In conclusion, BVS for CTO seems to be an interesting strategy with a high rate of technical success and low rate of cardiac events at midterm follow-up in selected patients.

Abstract
INTRODUCTION AND OBJECTIVES The aim of this study was to analyze the incidence of drug-eluting stent thrombosis (sirolimus or everolimus) in patients with chronic total coronary occlusions (CTO) and to determine its clinical implications and related factors. METHODS Data from the 12-month follow-up of the 207 patients included in the CIBELES trial with CTO were analyzed. RESULTS Stent thrombosis occurred in three patients, two definite and one probable (overall thrombosis rate: 1.4%). However, there were no cases of death or Q-wave myocardial infarction. In univariate analysis, patients with a higher incidence of stent thrombosis were those in whom the target vessel was the left anterior descending, who had single-vessel disease, were assigned to treatment with sirolimus-eluting stents, and those with smaller minimum luminal diameter immediately after the procedure. In multivariate analysis, the only independent predictor of stent thrombosis was minimal luminal diameter immediately after the procedure. CONCLUSIONS The rate of drug-eluting stent thrombosis in patients with CTO is relatively low (1.4%). The only independent predictor of stent thrombosis in this context was minimal luminal diameter after the procedure and the clinical presentation was in all cases relatively benign.

First-generation versus second-generation drug-eluting stents in current clinical practice: updated evidence from a comprehensive meta-analysis of randomised clinical trials comprising 31 379 patients. Open Heart 2014; 1:e000064. [PMID: 25332803 PMCID: PMC4189321 DOI: 10.1136/openhrt-2014-000064] [Citation(s) in RCA: 76] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2014] [Revised: 05/15/2014] [Accepted: 07/15/2014] [Indexed: 12/14/2022] Open
Abstract
Background First-generation drug-eluting stents (DES) have become the most widely used devices worldwide for management of coronary artery disease. As remote follow-up data were becoming available, concerns emerged in regard to their long-term safety. Second-generation DES were designed to overcome safety issues, but the results of randomised clinical trials remain conflicting. Methods We compared the safety and efficacy of first-generation versus second-generation Food and Drug Administration approved DES; the following devices were included: first-generation sirolimus-eluting stent (SES) and paclitaxel-eluting stents (PES); second-generation everolimus-eluting stent (EES), zotarolimus-eluting stent Endeavor and ZES-Resolute (ZES-R). Prespecified safety end points comprised ≤1 and >1 year: overall and cardiac mortality, myocardial infarction (MI), definite/definite or probable ST; efficacy end points were target lesion revascularisation and target vessel revascularisation. Composite end points were analysed as well. Results 33 randomised controlled trials involving 31 379 patients with stable coronary artery disease or acute coronary syndrome undergoing DES implantation were retrieved. No differences in mortality among devices were found. In the overall class comparison, second-generation DES were associated with a 22% reduction of odds of MI at short-term OR 0.77 (95% CI 0.68 to 0.89) p=0.0002; EES reduced the odds of definite-probable ST compared with PES: OR 0.33 (95% CI 0.15 to 0.73) p=0.006; First-generation SES along with second-generation EES and ZES-R showed similar efficacy in decreasing the odds of repeat revascularisation. Conclusions Second-generation EES and ZES-R offer similar levels of efficacy compared with first-generation SES, but are more effective than PES; however, only second-generation EES significantly reduced the incidence of MI and ST, and therefore should be perceived as the safest DES to date.

Abstract
BACKGROUND In head-to-head comparisons of coronary drug-eluting stents, the primary endpoint is traditionally assessed after 9-12 months. However, the optimum timepoint for this assessment remains unclear. In this study, we assessed clinical outcomes at up to 5 years' follow-up in patients who received two different types of drug-eluting stents. METHODS We undertook this multicentre, open-label, randomised superiority trial at five percutaneous coronary intervention centres in Denmark. We randomly allocated 2332 eligible adult patients (≥18 years of age) with an indication for drug-eluting stent implantation to the zotarolimus-eluting Endeavor Sprint stent (Medtronic, Santa Rosa, CA, USA) or the sirolimus-eluting Cypher Select Plus stent (Cordis, Johnson & Johnson, Warren, NJ, USA). Randomisation of participants was achieved by computer-generated block randomisation and a telephone allocation service. The primary endpoint of the SORT OUT III study was a composite of major adverse cardiac events-cardiac death, myocardial infarction, and target vessel revascularisation-at 9 months' follow-up. In this study, endpoints included the occurrence of major adverse cardiac events and definite stent thrombosis at follow-up times of up to 5 years. Analysis was by intention to treat. The trial is registered with ClinicalTrials.gov, number NCT00660478. FINDINGS We randomly allocated 1162 patients to receive the zotarolimus-eluting stent and 1170 to the sirolimus-eluting stent. At 5-year follow-up, rates of major adverse cardiac events were similar in patients treated with both types of stents (zotarolimus-eluting stents 197/1162 [17.0%] vs sirolimus-eluting stents 182/1170 [15.6%]; odds ratio [OR] 1.10, 95% CI 0.88-1.37; p=0.40). This finding was indicative of the directly contrasting results for rates of major adverse cardiac events at 1-year follow up (zotarolimus 93/1162 [8.0%] vs sirolimus 46/1170 [3.9%]; OR 2.13, 95% CI 1.48-3.07; p<0.0001) compared with those at follow-up between 1 and 5 years (104 [9.0%] vs 136 [11.6%]; OR 0.78, 95% CI 0.59-1.02; p=0.071). At 1-year follow-up, definite stent thrombosis was more frequent after implantation of the zotarolimus-eluting stent (13/1162 [1.1%]) than the sirolimus-eluting stent (4/1170 [0.3%]; OR 3.34, 95% CI 1.08-10.3; p=0.036), whereas the opposite finding was recorded for between 1 and 5 years' follow-up (zotarolimus-eluting stent 1/1162 [0.1%] vs sirolimus-eluting stent 21/1170 [1.8%], OR 0.05, 95% CI 0.01-0.36; p=0.003). 26 of 88 (30%) target lesion revascularisations in the zotarolimus-eluting stent group occurred between 1 and 5 years' follow-up, whereas 54 of 70 (77%) of those in the sirolimus-eluting stent group occurred during this follow-up period. INTERPRETATION The superiority of sirolimus-eluting stents compared with zotarolimus-eluting stents at 1-year follow-up was lost after 5 years. The traditional 1-year primary endpoint assessment therefore might be insufficient to predict 5-year clinical outcomes in patients treated with coronary drug-eluting stent implantation.

Abstract
Accurate assessment of coronary chronic total occlusion (CTO) lesion is essential to design an appropriate procedural strategy before revascularization. The present study aims to evaluate the significance of a single multislice computed tomography (MSCT) examination in patients with CTO lesion. We retrospectively analyzed the clinical data of 23 CTO lesions in twenty patients underwent computed tomography coronary angiography (CTCA) and SPECT. The CTCA was more powerful and sensitive to determine the CTO lesion length (100% v.s 47.8%) and to identify the length and location of calcification in occluded vessels compared with the coronary angiography (CAG). The LVEF measured by MSCT was comparable to that from the gated SPECT. Myocardial perfusion imaging showed that the location of the early defect region identified by MSCT was corresponded to the nuclide filling defect on the stressed 201thallium-SPECT imaging. The late hyperenhancement on MSCT was presented as incomplete nuclide filling on the 99mTc-MIBI imaging. The results suggested that a single MSCT examination in previous myocardial infarction without revascularization facilitates to provide some valuable information on the nature of the occluded lesion, myocardial perfusion and globe cardiac function, which would be helpful to design appropriate revascularization strategy in these subjects.

Abstract
Chronic total occlusions (CTOs) are often detected on diagnostic coronary angiograms, but percutaneous coronary intervention (PCI) for CTO is currently infrequently performed owing to high technical difficulty, perceived risk of complications, and a lack of randomized data. However, successful CTO-PCI can significantly increase a patient's quality of life, improve left ventricular function, reduce the need for subsequent CABG surgery, and possibly improve long-term survival. A number of factors must be taken into account for the selection of patients for CTO-PCI, including the extent of ischaemia surrounding the occlusion, the level of myocardial viability, coronary location of the CTO, and probability of procedural success. Moreover, in patients with ST-segment elevation myocardial infarction, a CTO in a noninfarct-related artery might lead to an increase in infarct area, increased end-diastolic left ventricular pressure, and decreased left ventricular function, which are all associated with poor clinical outcomes. In this Review, we provide an overview of the anatomy and histopathology of CTOs, perceived benefits of CTO-PCI, considerations for patient selection for this procedure, and a summary of emerging techniques for CTO-PCI.

Abstract
This study aimed at evaluating the outcome of Biolimus eluting stent (BES) implantation in the treatment of chronic total coronary occlusions (CTO). We identified patients who underwent successful angioplasty for a CTO lesion with ≥1 BES between June 2008 and March 2012. All patients were followed up for major adverse cardiac events (MACE), which comprised death, non-fatal myocardial infarction (MI), cerebrovascular accident, target vessel revascularization (TVR), target lesion revascularization (TLR) and stent thrombosis. 125 patients underwent successful CTO angioplasty with ≥1 Biolimus-eluting stents. Mean age was 63.8 ± 12.0 years, and 82.4 % were males. Lesion location was right coronary artery (n = 80, 64 %), left anterior descending artery (n = 35, 28 %) and left circumflex artery (n = 10, 8 %). During follow-up of 579 ± 293 days, all cause mortality was n = 8 (6.4 %) patients, non-fatal MI was n = 3 (2.4 %), TVR was n = 3 (2.4 %) and TLR was n = 1 (0.8 %). Overall MACE was, therefore, n = 15 (12 %). BES is safe and effective in treatment of CTO lesions, with a low rate of major adverse cardiovascular events during follow-up.

Abstract
OBJECTIVES To investigate the safety and efficacy of durable polymer drug eluting stents (DES) and biodegradable polymer biolimus eluting stents (biolimus-ES). DESIGN Network meta-analysis of randomised controlled trials. DATA SOURCES AND STUDY SELECTION Medline, Google Scholar, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) database search for randomised controlled trials comparing at least two of durable polymer sirolimus eluting stents (sirolimus-ES) and paclitaxel eluting stents (paclitaxel-ES), newer durable polymer everolimus eluting stents (everolimus-ES), Endeavor and Resolute zotarolimus eluting stents (zotarolimus-ES), and biodegradable polymer biolimus-ES. PRIMARY OUTCOMES Safety (death, myocardial infarction, definite or probable stent thrombosis) and efficacy (target lesion and target vessel revascularisation) assessed at up to one year and beyond. RESULTS 60 randomised controlled trials were compared involving 63,242 patients with stable coronary artery disease or acute coronary syndrome treated with a DES. At one year, there were no differences in mortality among devices. Resolute and Endeavor zotarolimus-ES, everolimus-ES, and sirolimus-ES, but not biodegradable polymer biolimus-ES, were associated with significantly reduced odds of myocardial infarction (by 29-34%) compared with paclitaxel-ES. Compared with everolimus-ES, biodegradable polymer biolimus-ES were associated with significantly increased odds of myocardial infarction (by 29%), while Endeavor zotarolimus-ES and paclitaxel-ES were associated with significantly increased odds of stent thrombosis. All investigated DES were similar with regards to efficacy endpoints, except for Endeavor zotarolimus-ES and paclitaxel-ES, which were associated with significantly increased the odds of target lesion and target vessel revascularisations compared with other devices. Direction of results beyond one year did not diverge from the findings for up to one year follow-up. Bayesian probability curves showed a gradient in the magnitude of effect, with everolimus-ES and Resolute zotarolimus-ES offering the highest safety profiles. CONCLUSIONS The newer durable polymer everolimus-ES and Resolute zotarolimus-ES and the biodegradable polymer biolimus-ES maintain the efficacy of sirolimus-ES; however, for safety endpoints, differences become apparent, with everolimus-ES and Resolute zotarolimus-ES emerging as the safest stents to date.

Abstract
BACKGROUND Whether ZES can further improve angiographic and clinical outcomes compared to SES still remains uncertain. OBJECTIVES The aim of this study was to assess the efficacy and safety of zotarolimus-eluting stents (ZES) compared with sirolimus-eluting stents (SES) in patients undergoing percutaneous coronary interventions (PCI). METHODS Major electronic information sources were explored for randomized controlled trials comparing ZES with SES among patients undergoing PCI during at least 9 months follow-up. The primary efficacy outcomes were target lesion revascularization (TLR), target vessel revascularization (TVR), and major adverse cardiac events (MACE); safety outcomes were stent thrombosis (ST), myocardial infarction (MI), and cardiac death. RESULTS Seven comparative studies were identified (a total of 5983 patients). When compared with ZES at 12-month follow-up, SES significantly reduced risk of MACE (relative risk [RR]: 0.74, 95% confidence interval [CI]: 0.61 to 0.89, p=0.002), and TLR (RR:0.39; 95% CI: 0.29 to 0.52; p<0.00001), without significant differences in terms of TVR (RR:0.68, 95% CI: 0.38 to 1.20; p=0.18), ST (RR:0.71; 95% CI: 0.39 to 1.31; p=0.28), cardiac death (RR:0.83; 95% CI: 0.49-1.42, p=0.50) or MI (RR:1.08; 95%CI: 0.80 to 1.45; p=0.62). CONCLUSIONS At 12-month follow-up, SES are superior to ZES in reducing the incidences of TLR and MACE in patients undergoing PCI, without significant differences in terms of TVR, ST, cardiac death, and MI.
