Podcasts about Atrial fibrillation

Cardiologist and electrophysiologist Dr. Gregory Marcus, chair of the American Heart Association scientific statement writing group, reveals evidence on coffee/caffeine and cardiovascular health. He discusses how earlier assumptions that caffeine triggers arrhythmias are complicated by genetics, individual risk factors, and mostly observational research. Marcus reviews randomized and observational findings: the CRAVE trial showed no increase in premature atrial contractions but more premature ventricular contractions on coffee days; a trial in post-cardioversion patients found less atrial fibrillation with daily coffee. Observational data suggest lower risks of type 2 diabetes, heart attack, stroke, and AFib among coffee drinkers, while heart failure risk may be lower at low intake but higher around 4–5 drinks/day. He cautions against extrapolating benefits to energy drinks, discusses additives like sugar, touches on alcohol, cannabis, Mediterranean/DASH diets, pollution, and evolving AFib treatments, wearables, and pacing/ablation technologies.

This week we speak with Dr. Ted O'Leary, Co-Director of Adult Congenital Heart Disease Electrophysiology at Boston Children's Hospital about a recent publication he authored on the use of pulsed field ablation (PFA) for the transcatheter ablation management of complex atrial arrhythmias in ACHD patients. How does PFA work and what are some of the potential advantages and disadvantages of this novel ablation energy technology? What are the advantages of a variable loop catheter in this setting? Is PFA going to supplant radiofrequency current for standard "SVT" ablations one day? These are amongst the questions reviewed with Dr. O'Leary this week. DOI: 10.1161/CIRCEP.125.014619

In this episode, CardioNerds Dr. Colin Blumenthal, Dr. Kelly Arps, and Dr. Yong Hao Yeo are joined by electrophysiology expert Dr. Bradley Knight to discuss atrial fibrillation (AF) management in challenging clinical scenarios. We explore arrhythmias in patients with pre-excitation syndromes, particularly Wolff-Parkinson-White (WPW) syndrome, and strategies for rhythm control. We also discuss AF management in pregnancy, adult congenital heart disease, and patients with tachycardia-bradycardia (tach-brady) syndrome. This episode provides essential insights into nuanced decision-making for the care of patients with complex arrhythmia profiles. Audio editing by CardioNerds academy intern, Grace Qiu.

PEARLS AF in WPW is a true emergency—AV nodal blocking agents can be deadly. In patients with WPW syndrome, AF can rapidly conduct through the accessory pathway, risking ventricular fibrillation and sudden death. Avoid AV nodal blockers like beta-blockers and calcium channel blockers. Catheter ablation is the first-line rhythm control strategy in WPW. Catheter ablation carries a Class I recommendation and offers >90% success. If antiarrhythmic drugs are needed, sodium channel blockers like flecainide or propafenone are preferred in patients without structural heart disease. In pregnancy, protecting the mother is protecting the fetus. An unstable mother means an unstable fetus. Rate control is the first step in AF with rapid ventricular responses and electrical cardioversion is safe when needed. Multidisciplinary care is essential. AF in congenital heart disease is often outside the pulmonary veins. Surgical scars and chamber remodeling in ACHD patients often lead to AF from non-pulmonary vein foci. Electrogram-based mapping and targeted ablation strategies are essential to increase success rate of durable rhythm control. Tachy-brady syndrome may require pacing to unlock therapy. AF may cause atrial myopathy and sinus node dysfunction. These patients often require permanent pacing to allow safe use of rate-controlling medications like beta-blockers and to prevent syncope or chronotropic incompetence. Notes: Notes drafted by Dr. Yong Hao Yeo Why is atrial tachycardia in patients with WPW syndrome dangerous? Patients with WPW commonly present with supraventricular tachycardia (SVT) due to atrioventricular reentrant circuits, either orthodromic or antidromic. This SVT can degenerate into AF. In the absence of AV nodal as the governor between the atrium and ventricles, the accessory pathway may conduct impulses rapidly and frequently. This can lead to dangerously high ventricular rates, predisposing patients to ventricular fibrillation and sudden cardiac arrest. What are some strategies for rhythm control in patients with WPW and atrial tachycardia? Catheter ablation is the first-line therapy (Class I recommendation), with a success rate of over 90%. Ablation reduces the risk of sudden cardiac arrest, though some patients may remain prone to AF. If ablation is not feasible/ contraindicated, sodium channel blockers such as flecainide and propafenone are good options in patients without ischemia or structural heart disease (Class IIa recommendation). Amiodarone should be avoided because it has a long half-life, can accumulate in the system, and may delay definitive treatment with catheter ablation. AV nodal blocking agents like beta blockers and calcium channel blockers should be avoided, as they are less effective at controlling ventricular rate in WPW and can increase conduction over the accessory pathway. These agents can also exacerbate the risk of rapid ventricular rates during AF and worsen left ventricular function. What are some special considerations in managing AF in pregnant patients? The primary goal in managing cardiovascular disease during pregnancy is to protect the mother, as fetal outcomes depend on maternal well-being. Therefore, while caution is necessary, we should avoid undertreating pregnant patients with AF. In cases of AF with rapid ventricular response (RVR), rate control is usually the first-line strategy, with beta blockers preferred over digoxin or non-dihydropyridine calcium channel blockers. It is then reasonable to initially observe for spontaneous conversion in stable patients. Antiarrhythmic drugs (AADs) are generally avoided during the first trimester, but clinical judgment on a case-by-case basis is essential. Evidence for the safety of AADs in pregnancy is limited, often derived from their use in other conditions such as fetal SVT. Flecainide and sotalol are reasonable options for rhythm control (Class IIa recommendation). Electrical cardioversion is considered safe in pregnancy and should be utilized when indicated (Do not forget!). There is no pregnancy-specific thromboembolic risk stratification tool. CHA₂DS₂-VASc scoring and the presence of risk factors like mitral stenosis can help guide anticoagulation decisions, though the magnitude of thromboembolic risk during pregnancy remains unclear. Rate control agents are typically continued during delivery due to the increased physiologic stress of labor and delivery. Multidisciplinary care is crucial and should involve obstetrics, maternal-fetal medicine, cardiology, and electrophysiology specialists. What are some key considerations for AF management in patients with adult congenital heart disease (ACHD)? Patients with repaired congenital heart disease are at increased risk for arrhythmias due to two main factors: surgical scars that create arrhythmogenic foci and mechanical remodeling of the atria or ventricles resulting from the underlying disease. In these patients with structural heart disease, sodium channel blockers may not be ideal antiarrhythmic options. When selecting an antiarrhythmic drug, clinicians must consider the nature of structural or surgical impairments, such as right bundle branch block or prolonged QT interval. It is also essential to assess renal and hepatic function (often impaired in patients with ACHD) to ensure appropriate metabolism and clearance of antiarrhythmic medications. Electrogram-based ablation strategies (those leveraging artificial intelligence are developing!) may help identify effective ablation targets, which are often outside the pulmonary veins in patients with ACHD. These individualized approaches can improve ablation success rates in this complex patient population. What makes tachycardia-bradycardia (tach-brady) syndrome a unique challenge in arrhythmia management? Patients who present with both AF and bradycardia, especially with syncope, require a thoughtful diagnostic approach to identify the underlying rhythm disturbance. Extended cardiac monitoring, including event monitors or implantable loop recorders, can help capture intermittent arrhythmias and correlate them with symptoms. AF may lead to atrial myopathy, and since the sinus node resides within the atrium, this can result in sinus node dysfunction—a hallmark of tachy-brady syndrome. Following spontaneous conversion from AF to sinus rhythm, sinus node dysfunction may persist, leading to prolonged pauses or chronotropic incompetence. Management becomes more complex when beta-blockers are needed for AF with RVR, as they can exacerbate bradycardia. Permanent pacemaker implantation is often the next step to consider. Permanent pacemaker implantation is often considered to facilitate safe rate control in these cases. In younger patients, aggressive AF burden reduction may prevent atrial remodeling and the development of true atrial myopathy, potentially avoiding pacemaker implantation.

This April 2026 Heart Rhythm Journal publication reports a sub-analysis of the CHAMPION-AF trial evaluating left atrial appendage closure (LAAC) versus oral anticoagulation in patients with atrial fibrillation who previously underwent catheter ablation. The analysis demonstrated that LAAC with the WATCHMAN FLX device provided comparable protection against stroke, systemic embolism, and cardiovascular death when compared with NOAC therapy, while also reducing long-term non-procedural bleeding events. These findings support consideration of LAAC as an alternative stroke prevention strategy in selected post-ablation AF patients through individualized, shared decision-making. Digital Education Committee Member Danesh Kella, MBBS, FHRS discusses this article from the Heart Rhythm Journal that preceded the Heart Rhythm 2026 Late-Breaking Clinical Trial. He is joined in the conversation by Jason T. Jacobson, MD, FHRS, Ammar M. Killu, MBBS, and Gregory M. Marcus, MD, FHRS.   Learning Objectives Describe the rationale for left atrial appendage closure as an alternative to chronic oral anticoagulation in patients with atrial fibrillation after catheter ablation. Review the efficacy and safety outcomes from the CHAMPION-AF sub-analysis comparing LAAC and NOAC therapy in post-ablation AF patients.  Discuss patient selection considerations and the role of shared decision-making when choosing stroke prevention strategies following AF ablation.    Podcast Contributors Danesh Kella, MBBS, FHRS Jason T.

This late-breaking sub-analysis from the CHAMPION-AF trial evaluated outcomes of left atrial appendage closure (LAAC) with the WATCHMAN FLX device versus oral anticoagulation in patients with atrial fibrillation who had previously undergone catheter ablation. Investigators found that LAAC provided similar protection against stroke, cardiovascular death, and systemic embolism compared with non-vitamin K oral anticoagulants (NOACs), while significantly reducing non-procedural bleeding events, regardless of prior ablation status. These findings suggest LAAC may be a viable alternative to long-term anticoagulation in select post-ablation AF patients through a shared decision-making approach.

Welcome to the first episode in this week's triple-header of late-breaking clinical trial coverage from Heart Rhythm 2026 in Chicago. In this episode Melissa E. Middeldorp, MPH, PhD from the Digital Education Committee sits down with David H. Birnie, MD and T. Jared Bunch, MD, FHRS to talk through this exciting late breaker. This late-breaking substudy of the ALONE-AF trial presented at Heart Rhythm 2026 evaluated whether discontinuing oral anticoagulation (OAC) after successful atrial fibrillation ablation impacts cognitive function in patients without long-term recurrence. The findings suggest that stopping OAC approximately one year post-ablation does not adversely affect cognitive outcomes, with cognitive scores improving similarly in both discontinuation and continuation groups among patients who remained arrhythmia-free. These results support the potential safety of OAC discontinuation in selected patients, while addressing an important gap in post-ablation management. Learning Objectives Understand the clinical rationale and current uncertainty surrounding continuation versus discontinuation of oral anticoagulation after successful AF ablation. Evaluate the impact of anticoagulation discontinuation on cognitive function in patients without recurrent atrial fibrillation. Apply emerging evidence from ALONE-AF and related studies to inform individualized decision-making on long-term anticoagulation management post-ablation.   Podcast Contributors Melissa E.

Lisa Salberg and Dr. Ethan Rowin break down new data on atrial fibrillation risk in patients taking myosin inhibitors for HCM. They explain what the latest research shows, how risk compares to traditional care, and what patients should watch for as treatment options continue to evolve.   This conversation was recorded April 28, 2026.

New cardiovascular data suggest pulsed field ablation may challenge antiarrhythmic drugs as first-line therapy for persistent atrial fibrillation, while real-world evidence positions apixaban as the preferred DOAC for younger patients with nonvalvular AF due to superior safety and effectiveness. Additional findings from the SENIOR-RITA trial indicate that routine invasive management may not benefit frail older adults with NSTEMI and could worsen outcomes in the most frail patients. Together, these studies highlight a growing shift toward more individualized cardiovascular treatment strategies.

Join host Melissa Middeldorp and her guests Marco Perez and Kristie Coleman for this installment of The Lead! This multicenter randomized controlled trial evaluated whether smartwatch-based rhythm monitoring improves detection of previously undiagnosed atrial fibrillation (AF) in cardiology outpatients aged ≥65 years with elevated stroke risk. A total of 437 participants were randomized to either 6-month monitoring with an Apple Watch integrating photoplethysmography-based irregular rhythm detection and single-lead ECG confirmation, supported by a telemonitoring adjudication pathway, or to standard care. The primary endpoint of new AF occurred significantly more often in the intervention group than in controls (9.6% vs 2.3%; HR 4.40), with many cases asymptomatic and detected earlier through wearable monitoring. All diagnosed patients were initiated on anticoagulation, and major adverse cardiovascular events were similar between groups. Overall, the study demonstrates that prolonged smartwatch-based screening embedded within a clinical workflow substantially increases AF detection in a high-risk population, highlighting the feasibility of wearable-enabled case finding while underscoring ongoing questions regarding clinical outcomes and optimal implementation. Learning Objectives Describe the design and key findings of a randomized trial evaluating smartwatch-based screening for atrial fibrillation in older patients at elevated stroke risk. Discuss the clinical implications, limitations, and broader evidence context of wearable-enabled atrial fibrillation detection within contemporary screening strategies.   Article Authors Nicole J. van Steijn, Isabel S.

Registered dietitian nutritionist Leyla Muedin discusses a New England Journal of Medicine paper (July 2024, cited via Holistic Primary Care) warning about drug-induced magnesium depletion, especially from diuretics, proton pump inhibitors (e.g., Nexium, Prilosec), and certain antibiotics. She notes magnesium is often not routinely measured despite links between deficiency and cardiovascular, metabolic, and neurological problems, including arrhythmias (AFib, long QT, torsades), endothelial dysfunction, and longer ICU stays. Prevalence estimates range from 7–11% (up to 20%) in hospitalized patients and 2–4% among outpatients, with higher rates among long-term PPI and diuretic users. She reviews symptoms and causes, explains limits of serum magnesium testing, highlights associations with diabetes, alcohol use, low potassium and calcium, and outlines evaluation options and oral repletion approaches, favoring better-absorbed forms like magnesium glycinate over oxide due to diarrhea risk.

CardioNerds (Dr. Ramy Doss, Dr. Kelly Arps, and Dr. Naima Maqsood) dive into the nuances of atrial fibrillation (AF) ablation with Dr. Jon Piccini. They provide a high-yield overview of AF ablation, guiding listeners from patient selection through post-procedural management. We review appropriate candidacy for catheter ablation across AF phenotypes, key elements of pre-procedural evaluation including imaging and anticoagulation strategy, and the fundamental procedural steps with pulmonary vein isolation as the cornerstone. The discussion compares lesion set strategies in de novo ablation and reviews currently used energy sources—including radiofrequency, cryoablation, and pulsed-field ablation—highlighting differences in safety and efficacy. They also examine surgical and hybrid approaches for selected patients and outline essential components of post-ablation care, including rhythm monitoring, anticoagulation decisions, and management of complications. This episode integrates contemporary evidence with practical insights to support clinicians delivering comprehensive AF ablation care. Audio editing for this episode was performed by CardioNerds intern Dr. Bhavya Shah. NOTE: This episode was recorded in March 2025. Since then, the OCEAN trial showed that among patients who had had successful catheter ablation for atrial fibrillation at least 1 year earlier and had risk factors for stroke, treatment with rivaroxaban did not result in a significantly lower incidence of a composite of stroke, systemic embolism, or new covert embolic stroke than treatment with aspirin.  Enjoy this Circulation 2022 Paths to Discovery article to learn about the CardioNerds story, mission, and values.
