Are the Appropriate Use Criteria (AUC) for revascularization still aligned with the latest evidence? New insights from ISCHEMIA challenge key assumptions. My two cents in @CircOutcomes It’s time to rethink outdated priorities. tinyurl.com/cupe7hx8

I think so, what else explains an initial high event rate which then subsides (aortic stenosis doesn’t get better!)? Great if you can manage the first 6 months of subtraction anxiety - event rate then tracks the TAVR arm. Psychology so important in clinical trials. @drjohnm

Excellent discussion of ORBITA-STAR by @michaeltct Simple findings like those made in this study pave the way to solve a major clinical problem. In stable patients, persistent angina is PCI’s Achilles’ heel @TCTMD @PCRonline @rallamee

Thanks to @JACCJournals and @PCRonline for showcasing, and the patients who made ORBITA-STAR possible! Hopefully a step toward more targeted treatment.

ORBITA-STAR at #EuroPCR is a fascinating & successful study of type of chest pain as a predictor of PCI success. Very difficult to ascertain if angina caused by ischemia is what patients felt. This was a concern of Gruentzig's 40 yrs ago! @rajkumar_chris @rallamee #AngioHistory

In ORBITA-STAR, angina verification with an ischaemic stimulus powerfully predicted response to PCI. #EuroPCR2024 Perhaps we have been too focused on treatment when the problem always lay in the diagnosis! Published today in #JACC jacc.org/doi/10.1016/j.… @rallamee

Q: Does blinding matter in RCTs of surgical procedures? A: Depends on the endpoint @JAMASurgery We compared placebo-controlled and open-label surgical trials to identify when the placebo effect is most powerful @rallamee @KatieEljadi @ImperialNHLI jamanetwork.com/journals/jamas…

Exciting insights from our @BSCMR Valve Consortium, presented at #CMR2024 and featured in #EHJ: In severe AS, myocardial scar detected by #whyCMR pre-operatively is linked to long-term survival post-AVR. This underscores theimportance of fibrosis for post-op risk stratification.
