AI for valves isn’t hype anymore: ECG→echo triage, automated quantification, and CT-driven TAVR planning are real—time to industrialize integration and close the equity gap.

Rationale for changing endpoints between the 1-year and 5-year results in the FAME-3 trial discussed at 32:50 in the video (https://t.co/gIQfzafE4N).

🔹Initial endpoint (1 yr): Included repeat revascularization to closely match SYNTAX trial.
🔹Long-term endpoint (5 yrs): Excluded repeat revasc to focus on harder endpoints (death, stroke, MI).
🔹Rationale: Repeat revasc is subjective, physician-dependent, and less prognostically relevant today.
🔹Goal: Provide clearer, unbiased long-term comparison (PCI vs CABG).

It was a pleasure to host @wfearonmd at @HeartInstitute earlier this month.

PCI versus CABG: The Ongoing Feud - William Fearon https://t.co/xUPDB4a0hm

🔹FAME-3 trial compared modern FFR-guided PCI vs CABG at 1 & 5 years.
🔹At 1 year: PCI didn't meet non-inferiority (higher repeat revasc).
🔹At 5 years: No diff. in hard endpoints (death/stroke/MI).
🔹PCI best in low SYNTAX; CABG in complex cases.
🔹Team-based decisions key.

Case Study by P. Thériault-Lauzier (@therlaup) et al.: Clinical Deployment of Real-Time Left Ventricular Ejection Fraction Estimation from Coronary Angiography https://t.co/LChf2iRCPq

#AIinMedicine

[Robert Avram @RobertAvramMD]

EXCITED To share our publication on the clinical Deployment of Real-Time LVEF estimation during coronary angiogram in @NEJM_AI !

CathEF, a deep learning model integrated into PACS-AI (https://t.co/XG1dVFtwzN), estimates left ventricular ejection fraction (LVEF) in real time from routine coronary angiography — without additional contrast or invasive steps.

Performance matched traditional ventriculography:
AUROC 0.84 for LVEF ≤50%
AUROC 0.90 for LVEF ≤40%

Slightly lower accuracy was seen in STEMI cases and right coronary artery lesions.

@RobertAvramMD @NEJM_AI @CIFAR_News Huge thanks to the incredible team at https://t.co/nuHyJK2ngk for your leadership and groundbreaking research. It’s a privilege to collaborate with you @RobertAvramMD. Changing cardiology, one algorithm at a time.

[Pascal T. Lauzier, MD, PhD @therlaup]

Thrilled to share our work in @NEJM_AI. We prospectively validated the CathEF model for estimating LV function from coronary angiograms in patients with ACS. We found a comparable diagnostic performance to ventriculography.
