Post-Procedural Angiography-Based Physiological Indices and Clinical Outcomes After Drug-Coated Balloon Treatment of In-Stent Restenosis

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...

Angiography-Derived vs Wire-Based Physiological Assessment in Coronary Artery Disease: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

This study aimed to determine whether angiography-based physiological assessment yields clinical outcomes comparable to those of conventional wire-based pressure measurements in patients with coronary artery disease (CAD) undergoing evaluation of intermediate coronary stenoses. A...
