Background

Drug-eluting stents (DES) have shown great improvement in reducing in-stent restenosis (ISR). However, the incidence of ISR was still a problem after DES implantation. Drug-Coated Balloon (DCB) has been accepted as a treatment for ISR-DES. Several studies have been conducted to assess the benefits of DCB for dealing with ISR-DES. However, the results remain conflicting.

Methods

The SURABAYA (reSUlt of dRug coAted Balloon AngioplastY versus drug-eluting stent for in-stent restenosis After drug-eluting stent implantation) Study is a meta-analysis to compare safety and efficacy of DCB treating ISR-DES. SURABAYA Study performed a systematic literature search from several electronic databases. The inclusion criteria were studies comparing DCB and DES to treat ISR-DES, both (Randomized Control Trial) RCT and observational study were acceptable. The exclusion criteria were studies comparing DCB and DES to treat ISR-BMS. The primary safety endpoint was cardiac death and the primary efficacy endpoint was target vascular revascularization (TVR). Secondary endpoints included myocardial infarction (MI), definite stent thrombosis, and major cardiovascular adverse events (MACE). Risk ratios with 95% confidence intervals (CIs) was calculated with the appropriate fixed or random-effects models.

Results

A total of 4 RCT and 4 observational study were selected, with 1.610 patients were pooled in our analysis. Comparing to DES, DCB had a similar outcome in primary safety end point, cardiac death (RR=1.07 [95% CI, 0.48-2.35], p=0.87). However, DCB had higher risk of primary efficacy end point, TVR (RR=1.30 [95% CI, 1.01-1.68], p=0.04). myocardial infarction (RR=0.79 [95% CI, 0.41-1.52], p=0.48), stent thrombosis (RR=0.50 [95% CI, 0.09-2.65], p=0.42), and MACE (RR=1.21 [95% CI, 0.93-1.59], p=0.15).

Conclusion

DCB is as safe as DES in treating ISR-DES. DCB also has comparable outcomes in myocardial infarction, stent thrombosis, and MACE. However, DCB is less effective than DES to prevent an incident of TVR.
