| Summary: | The evolution of percutaneous coronary intervention (PCI) has led to significant advances in drug-coated balloon (DCB) technology, offering a stent-free alternative for treating coronary artery disease. While paclitaxel-coated balloons (PCBs) have been the standard, sirolimus-coated balloons (SCBs) are emerging as a viable alternative with distinct pharmacokinetic and clinical benefits. This review explores the mechanisms of action of paclitaxel and sirolimus, their impact on different plaque morphologies, and the clinical implications of DCB selection. Paclitaxel facilitates positive vascular remodeling and is particularly effective in fibrotic and lipid-rich plaques, but its poor penetration in calcified lesions remains a limitation. Sirolimus, with its homogeneous tissue distribution and anti-inflammatory properties, is better suited for unstable, lipid-rich, and inflammatory plaques, where it promotes plaque stabilization. Recent randomized trials and meta-analyses have compared SCBs vs. PCBs in both de novo lesions and in-stent restenosis, showing non-inferior outcomes. Additionally, DCBs demonstrate comparable efficacy to DES in small vessel disease, reducing the need for permanent metallic scaffolds. This review summarizes the current evidence on DCB selection based on plaque characteristics and highlights areas for further investigation in personalized PCI strategies. Given the narrative review design, the authors conducted a comprehensive literature search using databases such as PubMed and MEDLINE. Keywords included “drug-coated balloon”, “paclitaxel-coated balloon”, “sirolimus-coated balloon”, “in-stent restenosis”, and “plaque morphology”. Studies were selected based on relevance, including randomized controlled trials, registries, and meta-analyses. No formal inclusion/exclusion criteria or systematic screening were applied due to the nature of narrative synthesis. |
