Residual angina after PCI is common. The explanation depends on the interaction between microvascular dysfunction and the epicardial disease pattern 🎯 Focal CAD: successful PCI unmasks coexisting CMD. 〰️ Diffuse CAD: persistent epicardial resistance remains the dominant cause.

First time at #EuroPCR @PCRonline a dedicated Physiology Course. Physiology is becoming available in every case—#CCTCA, angio or invasive. Understanding the fundamentals is key to interpretation and decision-making. FFR is not only an index; it is a concept. Join us on Monday 18 in Paris. #Physiology #FFR Don't miss it pcronline.com/Courses/EuroPC…

FAME 2 long-term just published in @NatureMedicine Stable CAD with FFR ≤0.80: FFR-guided PCI + MT vs MT alone ↓ death/MI/urgent revasc (33.6% vs 41.3%, win ratio 1.25, NNT~17)—mainly ↓ urgent revasc (10.1% vs 25.2%). nature.com/articles/s41591-0… At 10+ yrs Physiology still matters -> My digital avatar explains it all 🎥🤖 👇 @crfheart @TCTMD @PCRonline @AbbottNews @Heartflow @JACCJournals #FFR #PCI #StableCAD

Kicking off #TCT2025 on Saturday morning, we will present the 1 year clinical outcomes of patients treated with PCI in Focal vs Diffuse disease #PPG Physiology will become more clinically relevant than ever before 💪🏻
🚨 #TCT2025 Late-Breaker alert! Dr. @ColletCarlos will share how Pullback Pressure Gradient (PPG) impacts clinical outcomes one-year after #PCI. PPG is a predictive tool that quantifies focal coronary disease to enable precise PCI decision-making for better patient outcomes.¹⁻³ Don’t miss out: bit.ly/4qelAkO #CardioEd

Outstanding work! 👏 This is the first randomized study comparing resting and hyperemic pullbacks. 🔑 Key finding: Both resting (iFR) and hyperemic (FFR) pullbacks are equally influenced by lesion cross-talk. ✅ This settles a long-standing debate in the physiology field.
Is FFR/iFR the same in the LAD and LCx in isolated LMCA disease? We are excited to share our #disruptive findings, online @CircIntv today ahajournals.org/doi/10.1161/… ‼️ All pressure-based indices are LOWER in the LAD than in LCx (misclassification 21% by FFR 28% by iFR)

This first randomized comparison of FFR & iFR in serial #cvCAD shows that both FFR & iFR pullbacks overestimate hemodynamic benefits of #PCI. Post-PCI physiology should be routinely performed in diffuse & serial disease. jacc.org/doi/10.1016/j.jcin.… @divaka_perera @mattlkw #JACCINT

Thought-provoking new analysis from the FLAVOUR trial by Zhang et al this week. Should PCI be guided by intracoronary physiology or by intacoronary imaging? Do we need the best of both worlds? Thanks to @JACCJournals for the invitation to comment. shorturl.at/dyGuT

Thanks @Heart_BMJ ! Abnormal coronary microvascular function is associated with increased epicardial atherosclerotic plaque burden. Could this be the link between CMD and increased MACE in #INOCA?@TomJFord @DavidCarrick14 @DamienCollison @ColinBerryMD heart.bmj.com/content/early/…
