Honoured to present our work on cardiorespiratory fitness and atrial remodeling at #HRS24 @HRSonline last week. Manuscript available online as simultaneous publication at @JACCJournals https://t.co/NzPozQy53c

🚨 New from #CHRD in JACC EP: Obesity presents a unique phenotype of HFpEF In AF patients, obesity & ↑ epicardial adipose tissue drive higher atrial pressures, pericardial restraint & greater prevalence of HFpEF Targeting weight loss may improve symptoms & reduce HF risk.

Obesity is a major driver of AFib. Our latest review in @HeartLungCirc explores the pathophysiological links & how lifestyle & pharmacological therapies may help reduce AF burden. 📄 : https://t.co/X93Jn6jd8s @Elliott_AD @JonathanAriya @melissaemm1 @PrashSanders

Looking forward to presenting the CAAN-AF study as a Late-Breaking Clinical Trials: recent advances in CIED therapies at #ESC2025 @escardio Link to methodology paper: DOI: 10.1016/j.hroo.2025.07.018 @UniofAdelaide #CHRD @nhmrc

@JonathanAriya shows that many AF ablation patients have subclinical HFpEF — elevated filling pressures, impaired reserve, yet no ‘diagnosis.’ If it’s there and it matters, shouldn’t we be treating HFpEF while we ablate? 🔥❤️‍🩹 #AFib #HFpEF #CSANZ2025

HFpEF + AFib = a toxic duo. @JonathanAriya work shows AF isn’t just a bystander — it worsens haemodynamics, drives symptoms, and fuels hospitalisations. If AF is part of the problem, shouldn’t ablation be part of the solution? 🔥❤️‍🩹 #AFib #HFpEF #CSANZ2025

🚨 New study out now! Can your pacing lead handle a hypertrophied septum? We developed an ex-vivo ovine model to test Stylet Driven vs Lumen Less Leads in thick septa. 🧠 SDLs went deeper, faster, and with less torque. 📄 https://t.co/dVN4BpynDV #EPeeps #LBBAP #CardioTwitter

Not all symptoms are equal‼️ @JonathanAriya outlining the significance of Exertional Symptoms 🗣️ in the LAST-AF cohort. Another piece in the puzzle for EARLIER detection of HFpEF in patients with AF #HRS2025 #CHRD

"Invasive and non-invasive assessment to determine correlation of symptoms and HFpEF in patients with AF" 🌟 A fantastic presentation by @JonathanAriya, shedding light on the significant impact of HFpEF in patients, even following successful AF ablation. @UniofAdelaide #CHRD

Outstanding talk as usual from @PrashSanders! #Obesity leads to #HFpEF physiology thru ⬆️ volume load ⬆️ pericardial restraint (epicardial fat) ⬆️ atrial cardiomyopathy Which leads to #AFib from ⬆️ intracardiac pressures ⬇️ cardiac reserve ⬇️ exercise capacity #WAFib2025

impact of atrial fibrillation on oxygen uptake and hemodynamics in patients with heart failure: A systematic review and meta-analysis

#JACCCEP multicenter RCT shows that CSI in addition to PVI & roofline ablation for first-time procedures in a small population of pts w/ paroxysmal & early persistent #AFib does not reduce AF recurrence after 2 yrs follow-up https://t.co/R4HPXJP0uj @JonathanAriya @PrashSanders

A big few days at The Asia Pacific Heart Rhythm Society Scientific Sessions in Sydney for the Centre for Heart Rhythm Disorders team sharing our research over: 🗣️ 27 talks 📊 26 posters @UniofAdelaide @sahmriAU @SAHMRI_Heart #CHRD #APHRS2024

#APHRS2024 #JACCCEP LBCT SimPub: Adjunctive coronary sinus isolation as part of a de novo ablation strategy does not confer any additional benefit above pulmonary vein isolation and roofline for the treatment of high-burden atrial fibrillation. https://t.co/KZAEQVTwi0 #AFib

#APHRS2024 #LBCT Coronary Sinus Isolation for high burden #AFib presented by @JonathanAriya Published simultaneously in @JACCJournals https://t.co/4YdYkaMujo @PrashSanders @melissaemm1 @Ant_G_Brooks @Kadhimad @Rajiv_EP @drrpathak #CHRD @UniofAdelaide @CentralAdlLHN

🧍‍♀️ associated with lower LA strain, perhaps some reason why women experience higher arrhythmia recurrence @aphrs2024 @PrashSanders

@Kadhimad describing the ‘Freeman’ experience on MRI for patients with CIEDs. No major or minor adverse events. MRIs are ‘very largely’ safe for patients with CIEDs @aphrs2024

Another great presentation from @JonathanAriya. @aphrs2024 is underway! 🫀

@JonathanAriya discussing the association and mechanisms of cardiorespiratory fitness and AF in the Physical Activity and Endurance Athletes and AF session. #APHRS2024

Looking at current interventions and future opportunities, @JonathanAriya of @UniofAdelaide discusses heart failure and AF at the @OzCvA Atrial Fibrillation Clinical Theme Workshop. @VandenbergJamie @PrashSanders @JonKalmanEP

Do we need to screen HFpEF for AF? Should you try DCC to assess symptom burden when sinus rhthym is restored? Intervene early, pursue sinus rhythm aggressively, reduce and reverse remodelling? A lot of yeses today!!! @Phiso_de Michele Brignole, @RositaZakeri, @nmarrouche
