Tell me you don’t regularly take care of patients without saying a word. Clearly this question writer spends more time w a keyboard than a stethoscope 👇🏻

A) what do you use for sedation w/ those hemodynamics and b) how many seconds will this pt stay in SR? H/t @jasonryanmd

I don’t think any woman goes through their training not wanting to work. Over 50% of those who responded did a fellowship.

There is a problem with our health system that needs to be resolved to keep the women and men we train in medicine. Including reducing the stress of the job, often due to mistreatment, discrimination & lack of opportunities for leadership roles, in addition to inequity in pay that has long been established.

And just like that — #HRS2026 is officially a wrap! 🎬

For our final wrap up of the week, we're reflecting on an incredible HRS Gala, the energy of the President's Social, and the late-breaking science that kept us on the edge of our seats through the very last session. See the full discussion here #EPeeps ➡️ https://t.co/zzKXdAQdUe

Four days of connection, discovery, and moments we won't forget. We hope everyone walked away inspired, energized, and ready for what's next — because we sure did.

Until next year — see you in San Francisco for #HRS2027! 🌁✨

[Heart Rhythm Society @HRSonline]

An unforgettable evening. A powerful impact.

The 2026 Heart Rhythm Gala brought together more than 850 members of the global EP community and raised over $875,000 to support the missions for the Heart Rhythm Society and @HeartRhythmAdvo.

At the heart of the evening were the voices of patients and clinicians, captured in our “Why We Gather” video, reminding us of the purpose behind our work and the impact we can make together.

Safety. Quality. Physician Alignment. 🏥

The shift of EP procedures to Ambulatory Surgery Centers is accelerating — but what does it really take to get it right?

#HRStv host @MehakDhande sits down with @DrJMarine and @DrRoderickTung to unpack the evolving ASC landscape in EP.

📢LBCT #HRS2026 (+ Simultaneous pub @hrs_journal ) *⃣ Proton Beam Cardiac Radioablation for VT @MayoClinicCV #SciComms
*⃣ Catheter-free proton beam radioablation (CRA) for refractory VT
➡️First-in-human feasibility study (n=7 treated)
• Advanced cardiomyopathy (median LVEF ~26%)
• Refractory VT despite AADs + prior ablation
• Single fraction 30 Gy proton therapy
🎯 Key concept:
Protons enable highly conformal targeting (Bragg peak) with minimal exit dose
➡️Efficacy signal:
• VT burden ↓ 79%
• Event rate: 7.24 → 1.52 events/patient-month
👉 Substantial but incomplete (recurrence in most pts)
➡️Safety:
• No probable/definite treatment-related SAEs
• No acute ICD dysfunction or peri-procedural complications
• Limited off-target radiation (~4% myocardium ≥20 Gy)
➡️ Mechanistic insight:
• Effect may be delayed (weeks–months)
• May reflect fibrosis + EP remodeling, not immediate ablation
🤔Context:
• Very high-risk population (HF-driven mortality)
• Small, single-arm feasibility study
• No control group; targeting remains non-standardized
• Long-term toxicity unknown
🧑‍🎓Takeaway:
Proton CRA is a feasible, noninvasive VT strategy with encouraging early safety and meaningful VT reduction
…but remains early-stage and hypothesis-generating
