Drug-Eluting Balloon versus New-Generation Drug-Eluting Stent for the Treatment of In-Stent Restenosis: An Updated Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Currently, drug-eluting balloon (DEB) appears to be an attractive alternative option for the treatment of in-stent restenosis (ISR). Nevertheless, the clinical outcomes of DEB have seldom been compared to those of new-generation drug-eluting stent (DES). Thus, this meta-analysis aimed to evaluate the safety and efficacy of DEB compared to those of new-generation DES in the treatment of ISR.

Methods

A comprehensive search of electronic databases including PubMed, EMBASE, and Cochrane Library up to November 2, 2017 was performed to identify pertinent articles comparing DEB to new-generation DES for the treatment of ISR. In addition, conference proceedings for the scientific sessions of the American College of Cardiology, American Heart Association, European Society of Cardiology, Transcatheter Cardiovascular Therapeutics, and EuroPCR were also searched. The primary endpoint was target lesion revascularization (TLR) at the longest follow-up. Dichotomous variables were presented as risk ratios (RR s) with 95% confidence intervals (CI s), while the overall RR s were estimated using the Mantel-Haenszel random-effects model.

Results

Five randomized controlled trials (RCTs) and eight observational studies involving 2743 patients were included in the present meta-analysis. Overall, DEB was comparable to new-generation DES in terms of TLR (RR = 1.24, 95% CI: 0.89-1.72, P = 0.21), cardiac death (RR = 1.55, 95% CI: 0.89-2.71, P = 0.12), major adverse cardiovascular event (RR = 1.21, 95% CI: 0.98-1.48, P = 0.07), myocardial infarction (RR = 1.12, 95% CI: 0.72-1.76, P = 0.62), and stent thrombosis (RR = 0.95, 95% CI: 0.38-2.42, P = 0.92). However, DEB was associated with higher risk of all-cause mortality than new-generation DES (RR = 1.65, 95% CI: 1.09-2.50, P = 0.02). This was especially true in the real-world observational studies (RR = 1.79, 95% CI: 1.12-2.88, P = 0.02). In RCTs, however, no significant difference was found between the two treatment strategies in the risk of all-cause mortality.

Conclusions

The current meta-analysis showed that DEB and new-generation DES had comparable safety and efficacy for the treatment of ISR in RCTs. However, treatment with DEB was associated with higher risk of all-cause mortality in the real-world nonrandomized studies.

Project description:AimsIn-stent chronic total occlusion (IS-CTO) represents a unique challenge for percutaneous coronary intervention. Whether the optimal treatment for IS-CTO is angioplasty with paclitaxel-coated balloons (PCBs) or repeat stenting with drug-eluting stents (DESs) is unclear. We aimed to evaluate the long-term clinical outcome of PCB angioplasty and DES repeat stenting for DES IS-CTO.MethodsWe retrospectively included patients with DES IS-CTO who underwent successful PCB angioplasty or DES repeat stenting from January 2016 to December 2019. The primary endpoints were major adverse cardiac events (MACEs), including cardiac death, myocardial infarction, and target lesion revascularization (TLR). Cox proportional hazards model was performed to compare the risk of MACEs between PCB angioplasty and DES repeat stenting, and to further explore the prognostic factors of patients with DES IS-CTO.ResultsA total of 214 patients with DES IS-CTO were enrolled: 78 patients (36.4%) treated with PCB and 136 patients (63.6%) treated with DES respectively. The median follow-up was 1160 days, and MACEs were observed in 28.2% of patients with PCB angioplasty versus 26.5% of patients with DES repeat stenting (P = 0.784), mainly driven by TLR (21.8% vs. 19.9%, P = 0.735). There was no significant difference in the risk of MACEs between the PCB group and the DES group (hazard ratio [HR] 1.25, 95% confidence interval [CI] 0.64-2.46, P = 0.512). Multivariate Cox analysis revealed that chronic kidney disease and ≥ 3 stent layers in the lesion were independent predictors of MACEs, while switching to another antiproliferative drug was an independent protective factor (all P < 0.05).ConclusionsPCB angioplasty was an effective alternative treatment strategy for DES IS-CTO, which had similar long-term outcomes to DES repeat stenting in contemporary practice, but both were accompanied by a high rate of long-term MACEs. Improving the poor prognosis of patients with DES IS-CTO remains a challenge.

Project description:BackgroundDrug-coated balloon as a novel therapeutic strategy has been used to treat restenosis in cases of bare metal and drug-eluting stents. However, evidence of its safety and efficacy is scarce in de novo small coronary artery vessel disease. This meta-analysis aimed to compare the safety and efficacy of the drug-coated balloon and the drug-eluting stent.MethodsThe PubMed, EMBASE, Web of Science, and Cochrane library databases were searched for studies published up to October 17, 2018. Studies comparing the drug-coated balloon with the drug-eluting stent strategy in patients with de novo small coronary artery vessel disease (reference diameter, <3 mm) were identified. The clinical outcomes were nonfatal myocardial infarction, cardiac death, all-cause death, target lesion revascularization, and target-vessel revascularization. Data were analyzed using the statistical software RevMan (version 5.3). Fixed effects models were performed to calculate the pooled odds ratios (ORs) and 95% confidence intervals (95% CIs). Sensitivity analyses were used to detect potential sources of heterogeneity, while subgroup analyses were implemented to assess the differential effects.ResultsThree randomized controlled trials and 3 nonrandomized controlled studies were identified. Six studies including a total of 1800 patients compared the differences between the drug-coated balloon and the drug-eluting stent strategies in patients with de novo small coronary artery vessel disease. The results indicated that the drug-coated balloon strategy was associated with a significant reduction in nonfatal myocardial infarction (OR 0.53, 95% CI 0.31-0.90, P = .02) compared with the drug-eluting stent strategy, while insignificant inter-strategy differences were observed in cardiac death (OR 1.56, 95% CI 0.73-3.33, P = .25), all-cause death (OR 0.56, 95% CI 0.25-1.23, P = .15), target lesion revascularization (OR 1.24, 95% CI 0.73-2.1, P = .43), and target-vessel revascularization (OR 0.95, 95% CI 0.59-1.52, P = .84).ConclusionsThis meta-analysis suggests that the drug-coated balloon strategy is noninferior to the drug-eluting stent strategy, delivering a good outcome in nonfatal myocardial infarction, and can be recommended as an optimal treatment strategy in patients with de novo small coronary artery vessel disease. Larger randomized controlled studies with longer follow-up periods are needed to further confirm the benefits of the drug-coated balloon strategy.
