Heart Rhythm Society and sunny San Diego brought together the biggest HRS in years, with everything from custom presentation theaters to exciting afterparties. We hope everyone who attended HRS 2025 had as much fun as we did, and we hope all of you enjoy these top-six takeaways from electrophysiology’s biggest weekend of the year.
HRS Keeps Growing – The HRS annual meeting surpassed its pre-COVID numbers, as HRS 2025 crossed the 10k attendee mark (up from 9,588 last year), and the conference’s packed exhibit hall reflected the new growth.
Goodbye RFA, Hello PFA – Pulsed field ablation stepped on stage last year, but it’s now the star in the spotlight, with every major biotech firm touting a PFA device, and even Kardium, an independent contender aiming to best them all in design and outcomes.
EP’s Data Boom – As EP’s scientific studies grow, the thirst for data inspired several device data management companies to show up this year, as they offered up new ways to process procedural and ECG data for researchers and clinicians alike.
PFA and Pacemaker Results – HRS’ late breaker presentations were dominated by PFA safety and efficacy studies with a smattering of pacemaker studies targeting the left bundle branch, speaking to the innovations in more efficient ablation and pacing.
AI Momentum Remains – AI continued its strong presence at HRS, but this year it was all about integration and supporting modalities from ECG to periprocedural Echo. Almost all remote patients monitoring vendors and device data managers mentioned AI in their products in some way.
RPM Maturation – Speaking of RPM, the industry showed a lot of maturity this year, with established incumbents growing the market while innovative start-ups try to disrupt the space with new device form factors and data applications.

- iRhythm Zio Stands Out: Latest data from the AVAVLON study indicates that iRhytm’s Zio Long-Term Continuous Monitoring could lead to higher diagnostic yield and better outcomes compared to other LTCM products. AVALON examined 428k patients and found that those who used the Zio LTCM service had the highest adjusted odds of diagnosing their arrhythmia within 90 days (2X higher than Holter monitors, 1.69X higher than AEM, and 1.56X higher than other LTCMs). Zio LTCM also had the lowest probability of re-testing and cardiovascular events.
- Abbott AVEIR’s Early Results: Presented as an HRS late-breaker, Abbott’s first-in-human study for its AVEIR leadless pacemaker suggests that the device could effectively perform left bundle branch area pacing (LBBAP). Among 14 patients enrolled to receive the AVEIR LP, 10 successfully completed the procedure and LBBAP capture was observed in 5 out of those 10 patients. Freedom from serious adverse events within 1 month of implantation was 85.7%, suggesting the AVEIR device achieved clinically acceptable intraprocedural electrical performance and safety.
- Message Received for mRNA Therapy in ARVC: Examining mouse models of arrhythmogenic right ventricular cardiomyopathy (ARVC) caused by Dsc2 gene loss, researchers discovered that a single dose of Dsc2 mRNA restored heart size and function for 2–3 months. The intervention also worked in mice with pressure overload–induced RV dysfunction. Dsc2 variants account for 1.6% of ARVC cases, and current therapies with beta-blockers or antiarrhythmics don’t improve survival benefits.
- OCT Beats Angio for Stent Placement: Results from the CALIPSO trial suggest intravascular optical coherence tomography is more accurate than conventional angiography for guiding stent placement in patients with calcified coronary lesions. The JAMA Cardiology study examined 134 patients, finding that stents placed under OCT guidance had a 23% larger minimal stent area (6.5 vs. 5 mm2), with smaller areas boosting the risk of stent failure. OCT can be especially valuable in preparing calcified lesions before stent placement, such as with intravascular lithotripsy.
- Transverse’s Series B2: Transverse Medical completed its Series B2 financing round, securing over $10 million in new capital for the development of its POINT-GUARD Cerebral Embolic Protection (CEP) device for use during TAVR. The fresh funds will support POINT-GUARD’s active Feasibility Clinical Study in Australia. Transverse will also use some of the funding to expand its engineering, regulatory, quality, and operating teams as it prepares for pivotal trials and FDA IDE submission.
- Another DCB on The Way? The FDA granted Orchestra BioMed an Investigational Device Exemption (IDE) to test an updated design of its Virtue Sirolimus AngioInfusion Balloon (SAB) in the Virtue Trial. The IDE gives Orchestra BioMed FDA regulatory clearance to begin a U.S. pivotal clinical trial comparing its Virtue SAB to the Boston Scientific AGENT paclitaxel-coated balloon which is currently the only drug-coated balloon approved for a coronary indication.
- HRS/ACC Ablation Discharge Guidelines: New HRS/ACC guidelines suggest many patients can avoid an overnight stay after intracardiac catheter ablation procedures. The new document outlines discharge eligibility criteria, including no decompensated HF or unstable medical comorbidities that need acute management post-procedure. Proximity of the patient’s home to the hospital and his/her social support are also among the factors physicians should consider before discharging ablation patients.
- HeartBeam Earns VALID Results: Results from the VALID-ECG study suggest HeartBeam’s portable synthesized 12-lead ECG device could be as good as the ones taken in hospitals. Researchers in VALID-ECG evaluated the average difference in ECG intervals and amplitudes between HeartBeam’s device and standard 12-lead ECGs, finding that the two had a 93.4% overall diagnostic agreement. As a result, HeartBeam believes its device could support diagnosis of arrhythmias similarly to standard 12-leads.
- Abbott MPU Recall: The FDA announced that Abbott is recalling the mobile power units (MPUs) associated with some of its HeartMate left ventricular assist devices (LVADs). This Class I recall covers certain MPUs used with both the HeartMate 3 LVAD and HeartMate II LVAD and warns that using the devices “may cause serious injury or death.” The recall stems from reports that the MPUs are suddenly turning on, turning off, or restarting and advises providers to return any unused devices directly to Abbott.
- FDA Approves Medtronic OmniaSecure: Medtronic received FDA approval for its OmniaSecure defibrillation lead for right ventricle placement. The OmniaSecure lead is catheter-delivered and connects to an implantable defibrillator to help treat various arrhythmias. Medtronic claims the OmniaSecure’s 1.6mm size makes it the world’s smallest defibrillation lumenless lead while reducing the risk of complications. Data from HRS 2025 also found that implanting the OmniaSecure in the Left Bundle Branch was associated with high defibrillation success in 100% of patients.
- X-Ray AI Predicts Heart Disease: Chest X-ray isn’t usually thought of as a cardiac imaging modality, but AI could change that. As part of a JACC: Advances study, researchers from South Korea tested an AI algorithm that detects heart disease by analyzing cardiovascular borders on chest X-rays. Testing 44.6k patients, the algorithm showed potential in classifying and stratifying a patient’s risk of a cardiac abnormality, and calculated cardiothoracic ratios that predicted five-year risk of death or MI (HR=3.73).
