🛑Syncope-Stopper
#ESCCongress #HOTLINES #syncope
200 pts with unexplained syncope + high bradycardia risk (DROP ≥2), mean age ~80 (47% women 👏🏽🌟)→ upfront pacemaker 🆚 standard care
At 1 yr:
↓51% primary composite
↓53% recurrent syncope (11.1% vs 21.8%; HR 0.47, P=.037)
↓43% all-cause hospitalization
Upfront pacing may benefit selected high-risk pts

🚨 𝗕𝗥𝗘𝗔𝗞𝗜𝗡𝗚 from #ACC2026: Two major RCTs just challenged everything we thought about Impella pumps in cardiac care.
The results? Surprising.
The implications? Massive.
A thread on what every cardiologist needs to know 🧵👇

The CHAMPION trial does not forward the story of LAAO. No difference for major bleeding. No difference in all bleeding when procedural bleeding is included. Numerically worse for stroke. About 60% are CHADSVASC 2/3 WHO DON'T NEED OCCLUSION if ablation successful. #OCEAN

REHEALTH AF: first prospective study of ablation vs no ablation in pts ≥80 w/ #AFib. Ablation improved functional & structural outcomes; prognostic benefit emerged after multivariable adjustment. jacc.org/doi/10.1016/j.jacep… #JACCCEP #epAblation

.@hrs_journal AI is rapidly reshaping electrophysiology—from prediction to procedural guidance to ablation strategy.
🧵Here are 3 recent studies in @hrs_journal highlighting how AI may impact:
• AF prediction from ECGs
• Substrate-guided ablation outcomes
• Conduction system pacing precision
