Objectives. The aim of our study was to investigate the predictors of target lesion revascularization (TLR) and to compare the in-stent restenosis (ISR) progression rates of different 2nd-generation drug-eluting stents (DES). Background. The predictors of early and late TLR after 2nd-generation DES implantation have not been fully evaluated. Methods. We analyzed 944 stented lesions from 394 patients who had at least two serial follow-up angiograms, using quantitative coronary angiography (QCA) analysis. The study endpoints were TLR and the velocity of diameter stenosis (DS) progression. Results. TLR occurred in 58 lesions (6.1%) during the first angiographic follow-up period and 23 de novo lesions (2.4%) during the following second interval. Independent predictors for early TLR were diabetes mellitus (DM) (HR 2.58, 95% CI 1.29–5.15, p=0.007), previous percutaneous coronary intervention (PCI) (HR 2.41, 95% CI 1.03–5.65, p=0.043), and postprocedure DS% (HR 1.08, 95% CI 1.05–1.11, p<0.001, per 1%), while predictors of late TLR were previous PCI (HR 9.43, 95% CI 2.58-34.52, p=0.001) and serum C-reactive protein (CRP) (HR 1.60, 95% CI 1.28-2.00, p<0.001). The ISR progression velocity (by DS%) was 12.1 ±21.0%/year and 3.7 ±10.1%/year during the first and second follow-up periods, respectively, which had no significant difference (p>0.05) between the four types of DESs. Conclusions. Our data showed that predictors for TLR may be different at different time intervals. DM, pervious PCI, and postprocedure DS could predict early TLR, while previous PCI and CRP level could predict late TLR. Contemporary DESs had similar rates of ISR progression rates. Trial Registration. This study was retrospectively registered and approved by the institutional review board of Seoul National University Hospital (no. 1801–138-918).

Managing patients with in-stent restenosis (ISR) remains an important clinical challenge. In particular, large, randomized trials assessing the effect of drug-eluting balloons (DEB) in patients with de novo lesions are warranted. We investigated the effect of DEB on procedural complications, target lesion revascularization (TLR), and major adverse cardiac and cerebrovascular events in patients with drug-eluting stent ISR and de novo lesions. The clinical profiles of 238 consecutive patients treated for coronary ISR (n = 174) and de novo lesions (n = 64) using SeQuent Please paclitaxel-coated balloon were analyzed. Study end points were major adverse cardiac events (MACEs). At 1-year follow-up, TLR and MACEs occurred with acceptably low rates (5.0% and 6.3%, respectively). At 2.00 (0.74) years of follow-up, there was a significant difference in the rates of TLR between the ISR and the de novo lesions groups (14.4% [ISR] vs 3.1% [de novo], P = .028), and the occurrence of MACEs distinctly increased in the ISR group compared to the de novo lesions group (21.8% vs 6.2%, P = .009). The long-term outcomes of the ISR group were inferior to those of the de novo group (TLR, log-rank P = .019; MACEs, log-rank P = .010). Drug-eluting balloon for ISR and de novo lesions of small coronary vessels is effective and safe.

Abstract Aims Consensus is lacking regarding the best treatment for coronary in-stent restenosis (ISR). The two most effective treatments are angioplasty with paclitaxel-coated balloon (PCB) and repeat stenting with drug-eluting stent (DES) but individual trials were not statistically powered for clinical endpoints, results were heterogeneous, and evidence about comparative efficacy and safety in relevant subsets was limited. Methods and results The Difference in Anti-restenotic Effectiveness of Drug-eluting stent and drug-coated balloon AngiopLasty for the occUrrence of coronary in-Stent restenosis (DAEDALUS) study was a comprehensive, investigator-initiated, collaborative, individual patient data meta-analysis comparing angioplasty with PCB alone vs. repeat stenting with DES alone for the treatment of coronary ISR. The protocol was registered with PROSPERO (CRD42017075007). All 10 available randomized clinical trials were included with 1976 patients enrolled, 1033 assigned to PCB and 943 to DES. At 3-year follow-up, PCB was associated with a significant increase in the risk of target lesion revascularization (TLR) compared with DES [hazard ratio (HR) 1.32, 95% CI 1.02–1.70, P = 0.035; number-needed-to-harm 28.5]. There was a significant interaction between treatment effect and type of restenosed stent (P = 0.029) with a more marked difference in patients with DES-ISR and comparable effects in patients with bare-metal stent-ISR. At 3-year follow-up, the primary safety endpoint of all-cause death, myocardial infarction, or target lesion thrombosis was comparable between treatments (HR 0.80, 95% CI 0.58–1.09, P = 0.152). A pre-specified subgroup analysis indicated a significant interaction between treatment effect and type of DES used to treat ISR (P = 0.033), with a lower incidence of events associated with PCB compared with first-generation DES and similar effect between PCB and second-generation DES (HR 1.06, 95% CI 0.71–1.60, P = 0.764). Long-term all-cause mortality was similar between PCB and DES (HR 0.81, 95% CI 0.53–1.22, P = 0.310); results were consistent comparing PCB and non-paclitaxel-based DES (HR 1.42, 95% CI 0.80–2.54, P = 0.235). Myocardial infarction and target lesion thrombosis were comparable between treatments. Conclusions In patients with coronary ISR, repeat stenting with DES is moderately more effective than angioplasty with PCB at reducing the need for TLR at 3 years. The incidence of a composite of all-cause death, myocardial infarction, or target lesion thrombosis was similar between groups. The rates of individual endpoints, including all-cause mortality, were not significantly different between groups.

Background. In-stent restenosis (ISR) remains a common problem following percutaneous coronary intervention (PCI). However, the best treatment strategy remains uncertain. There is some controversy over the efficacy of drug-eluting balloons (DEBs) and second-generation drug-eluting stents (DESs) for treating ISR. Methods. A meta-analysis was used to compare the efficacy of the DEB and second-generation DES in the treatment of ISR. The primary endpoint is the incidence of target lesion revascularization (TLR). The secondary endpoint is the occurrence of target vessel revascularization (TVR), myocardial infarction (MI), all-cause death (ACM), cardiac death (CD), major adverse cardiac events (MACEs), minimum luminal diameter (MLD), late luminal loss (LLL), binary restenosis (BR), and percent diameter stenosis (DS%). Results. A total of 12 studies (4 randomized controlled trials and 8 observational studies) including 2020 patients with a follow-up of 6–25 months were included in the present study. There was a significant difference in the MLD between the two groups during follow-up (P=0.007, RR = 0.23, and 95% CI: 0.06–0.4 mm). There was no significant difference in LLL, BR, or DS% and the overall incidence of MACEs between the two groups. Subgroup analysis showed no significant difference in the incidence of primary and secondary endpoints when considering RCTs or observational studies only. Conclusions. The efficacy of the DEB and second-generation DES in the treatment of ISR is comparable. However, our results need further verification through multicenter randomized controlled trials.

✓ The authors report two cases of stent fracture and restenosis after placement of a drug-eluting device in the vertebral artery (VA) origin, and describe management of restenosis with the stent-in-stent technique. Two women, one 62 and the other 67 years of age, underwent stent placement in the VA origin to treat symptomatic and angiographically significant stenosis in this vessel. Sirolimus-eluting coronary stents (Cypher) were used in both cases. Four months after placement of the devices, the symptoms recurred. Follow-up angiography performed 5 months after insertion of the devices revealed a transverse stent fracture with separation of the fragments and severe in-stent restenosis in both cases. The restenoses were treated with reinsertion of coronary stents (Cypher and Jostent FlexMaster) by using the stent-in-stent technique. After stent reinsertion, the patients exhibited relief of symptoms. This paper is the first report of fracture in a drug-eluting stent and restenosis after stent placement in the VA origin. Restenosis caused by such a fracture can be managed successfully by performing the stent-in-stent maneuver. The physical properties of metallic devices, stent strut geometry, and anatomical peculiarities of the subclavian artery may be associated with stent fractures. Earlier follow-up angiography studies (within 6 months) are warranted.

Abstract Background: Recently, drug-eluting stents have been widely adopted rather than bare-metal stents in patients on chronic hemodialysis (HD) based on the extrapolation of data from patients on non-HD. However, whether DES implantation is associated with a reduced rate of in-stent restenosis (ISR) is unclear. We investigated the incidence of ISR and its predictors in patients on HD after drug-eluting stent implantation.Methods and Results: We analyzed 194 consecutive patients (331 lesions) on HD who underwent follow-up angiography after drug-eluting stent implantation. ISR was observed in 74 lesions (22.4%). Angiographically, the relative incidence of AHA/ACC type C lesion was increased (47% vs. 32%; P=0.043), the minimal lumen diameter (MLD) before DES implantation was smaller (0.82±0.49 vs. 0.97±0.45mm; P<0.01) and the lesion length (LL) was increased (30.2±16.1 vs. 24.4±12.1mm; P=0.023) in lesions with ISR compared to those without ISR. The rate of rotational atherectomy use was also increased in lesions with ISR compared to those without ISR (50% vs. 25%; P<0.01). In a multivariate analysis, the MLD before drug-eluting stent implantation (odds ratio [OR] =0.50, 95% confidence interval [CI] 0.27-0.91, P=0.024), LL (OR=1.02, 95% CI 1.00-1.04, P=0.030) and the use of rotational atherectomy (OR=2.71, 95% CI 1.55-4.72, P<0.01) were independent predictors of ISR. The incidence of ISR was similar between lesions treated with the first-generation (25.8%) and the second-generation DESs (20.4%).Conclusion: ISR was observed in 74 lesions (22.4%). A small MLD, long LL and the use of rotational atherectomy were independent predictors of ISR after drug-eluting stent implantation in patients on HD. There was no significant difference in ISR rate between the first- and the second-generation drug-eluting stents.

Introduction: Drug eluting balloons (DEB) were recently approved by FDA for peripheral artery interventions only. For coronary in-stent restenosis (ISR), the ACC/AHA/SCAI 2011 PCI guidelines have no recommendations on role for DEB. While ESC/EACTS 2010 PCI guidelines, have level IIa recommendation for DEB for ISR after a bare metal stent. The drug delivery kinetics with DEB allows shorter duration of dual anti-platelet therapy and has a potential role in ballooning side branches of a bifurcating lesion after stenting. Aim: To compare safety and efficacy of DEB angioplasty vs. plain old balloon angioplasty (BA) or drug eluting stent (DES) for treating coronary ISR. Methods and Results: A thorough search was performed on Pubmed, Embace and Google scholar databases for randomized control trials (RCT) comparing DEB vs. BA or DES for ISR. We compared target lesion revascularization (TLR) and MACE events for these groups. We also pooled data from registries and observation studies on DEB for outcome analysis. Total number of patients with DEB’s in our study was 3465, with 693 DEB’s in 8 RCT’s. Mean follow up period was 11 months. Pooled analysis showed significant benefit for DEB compared to plain old BA, for events of target lesion revascularization (OR= 0.25, p<0.0001), and death (OR=0.31, p<0.0001). Comparing DEB to DES, there was no statistical difference in outcomes comparing TLR (OR=1.4, p=0.14), MI or death (OR=0.65, p=0.39). Cumulative incidence of target lesion revascularization (TLR) with DEB was 6.7%. Conclusions: For coronary ISR, drug eluting balloon angioplasty is superior to plain old balloon angioplasty in terms of safety and outcomes. However, comparing drug eluting balloons vs. drug eluting stents in ISR, the outcomes are comparable and will need larger studies powered to make definitive recommendation.
