Drug-coated balloons in percutaneous coronary interventions: existing evidence and emerging hopes
No full textDrug-coated balloons (DCB) have been developed as an alternative to drug-eluting stents (DES) as a part of the “leave nothing behind” strategy following percutaneous coronary interventions (PCI). DCBs facilitate revascularization and delivery of an antiproliferative agent directly to a coronary artery lesion, without the need for DES implantation. Subsequently, DCBs promote positive vascular remodeling and allow for a shorter duration of dual antiplatelet therapy. Since the first reports on the successful treatment of coronary in-stent restenosis (ISR) with paclitaxel-coated balloon catheters in the year 2006, the use of DCBs has been growing, driven by reports of DCB application to treat ISR, bifurcation lesions, and small vessel disease. Contemporary clinical trials evaluating DCBs in large vessel disease and chronic total occlusions might further expand the indications for this technology. Attention has also been brought to the use of DCBs in patients with diabetes mellitus and acute coronary syndrome, especially those at high bleeding risk. This review aims to discuss the existing evidence and emerging hopes associated with DCBs, including technical aspects of DCB PCI and the use of DCBs in different clinical scenarios
Long-term outcomes following paclitaxel-coated balloons versus thin-strut drug -eluting stents for treatment of in-stent restenosis in chronic coronary syndrome (CCS Dragon-Registry)
No full textBackground: The long-term outcomes for patients with in-stent restenosis (ISR) presenting with chronic coronary syndrome (CCS) are not well studied. Aims: We aimed to investigate the outcomes for patients with drug-eluting stents (DES)-ISR and CCS undergoing percutaneous coronary intervention (PCI) with drug-coated balloons (DCB) or thin strut-DES. Methods: A total of 846 consecutive patients from the Dragon-Registry with CCS and DES-ISR who underwent PCI with thin (strut thickness <100 μm) strut-DES (381 [45%]) or paclitaxel-DCB (465 [55%]) for DES-ISR were enrolled between February 2008 and October 2021. The median follow-up was 1006 (IQR 426-1770) days. The primary outcome was target lesion revascularization (TLR). Secondary outcomes were target vessel revascularization (TVR) and device-oriented composite endpoint (DOCE: cardiac death, TLR, or target vessel myocardial infarction [TV-MI]). Results: Patients who received DES, compared with those who received DCB, had lower crude rates of TLR (hazard ratio [HR], 0.50 [95% CI, 0.34-0.74]; P <0.001), TVR (HR, 0.56 [95% CI, 0.39-0.86]; P <0.001), and DOCE (HR, 0.63 [95% CI, 0.45-0.88]; P = 0.007). The incidence of cardiac death and TV-MI were similar in both groups. After matching, the observed differences persisted in terms of TLR (HR, 0.54 [95% CI, 0.33-0.88]; P = 0.013), TVR (HR, 0.57 [95% CI, 0.41-0.80]; P = 0.009) and DOCE (HR, 0.65 [95% CI, 0.42-0.99]; P = 0.046) between the DES and DCB groups, respectively. Conclusions: In long-term follow-up of CCS patients undergoing PCI of ISR, the use of DES was associated with reduced rates of TLR, TVR, and DOCE compared with patients treated with DCB.</p
