Post-Procedural Angiography-Based Physiological Indices and Clinical Outcomes After Drug-Coated Balloon Treatment of In-Stent Restenosis: A Systematic Review and Meta-Analysis.
Drug-coated balloons (DCBs) represent an accepted approach for in-stent restenosis (ISR); however, post-procedural predictors for risk stratification remain limited. Angiography-based physiological parameters, including quantitative flow ratio (QFR), microvascular QFR (μQFR), and coronary angiography-derived fractional...
