This live PFA case explores patient experience under sedation, led by Domenico Della Rocca and Antonio Sorgente.

With more than 90% of patients reporting they would choose the same sedation protocol for repeat procedures, the discussion highlights patient-reported outcomes and comfort during PFA workflows. Faculty discussion with Devi Nair and others underscores how sedation strategy can be integrated into procedural planning while maintaining procedural efficiency.

A practical insight into how patient experience informs workflow decisions in contemporary PFA ablation.

This live case demonstrates best practices in conduction system pacing (CSP), led by Amr Abdin.

Using Boston Scientific stylet-driven leads, the procedure focuses on precise septal orientation and signal mapping. The RAO and LAO fluoroscopic views, along with the TAVI valve as an anatomical landmark, guide positioning to ensure optimal lead placement around two centimetres below the valve.

The workflow highlights careful rotation and the use of the locking helix tool, balancing efficiency with accurate electrical capture while avoiding unnecessary use of contrast or His mapping.

Consumer wearables and digital biomarkers are reshaping AF management.

In this episode of Rhythm Interventions Unplugged, Dr Devi Nair and Dr Rod Passman explore how these technologies track ectopy, activity, heart rate variability, and deceleration after exercise.

They discuss the challenges of integrating patient-generated data into clinical workflows, the evolving profile of the AF patient, and practical approaches for leveraging digital biomarkers to inform early detection, monitoring, and treatment.

Join a global discussion on the future of digital health in electrophysiology, curated for clinicians and EP specialists.

This case explores contact assessment during redo persistent AF ablation using pulsed field energy, led by Devi Nair.

Using the FARADRIVE™ Sheath from Boston Scientific, the workflow integrates contact-sensing software with ICE guidance to support procedural confidence during catheter positioning and lesion delivery.

The discussion focuses on how contact feedback can be useful, while recognising its current limitation when assessed from a single electrode. ICE remains central to the workflow, providing real-time confirmation of tissue contact before energy delivery.

Faculty discussion with Frank Cuocco also highlights how field tags, catheter contact and ICE findings can be interpreted together to guide lesion delivery.

This live case explores one of the enduring questions in Brugada syndrome: are the observed abnormalities driven by depolarisation, repolarisation, or a combination of both?

During epicardial mapping, Roderick Tung identifies characteristic high-frequency electrograms and local J-wave activity within the RVOT substrate. As mapping progresses, the team uncovers a broader area of abnormal electrograms than initially anticipated, highlighting the value of detailed epicardial assessment.

The discussion also touches on the challenges of mapping in regions with significant epicardial fat and the importance of correlating electrogram findings with anatomical imaging and clinical understanding of Brugada substrate.

This is what collaborative EP education looks like 👀

During Roderick Tung’s live case, Richard Schilling asks for ICE imaging live from the lab — and Devi Nair immediately walks through the anatomy in real time while ablation continues.

➡️Electrograms
➡️Physiology
All interpreted together as the case unfolds.

This is where mapping, physiology and imaging all come together 👀

During Roderick Tung’s live case, fractionation mapping is used to target the right anterior ganglionated plexus while monitoring for sinus acceleration and electrogram response in real time.

The case also uses ICE imaging to visualise catheter position at the SVC-RA junction and better understand the anatomy during ablation.

A fascinating look at how cardioneural ablation is guided by both signals and physiology.

Following remapping in sinus rhythm and identification of posterior wall low voltage, the discussion in A***n Sultan’s live case shifts from substrate identification to lesion strategy.

Can treatment extend beyond pulmonary vein isolation, and if so, how should lesion delivery be adapted?

The case explores the use of selective spline activation to direct energy only toward electrodes in contact with tissue, allowing additional lesion sets such as anterior lines to be created when appropriate. The discussion with Roderick Tung also raises an important anatomical consideration: the vestibule, a thicker region where achieving durable transmural lesions can remain challenging.

26/05/2026

During Julian Chun’s live case, an interesting discussion with Roderick Tung, focused on skeletal muscle recruitment during PFA and the use of nurse-assisted deep sedation with propofol.

With bipolar PFA technology, muscular recruitment appeared relatively limited in routine cases. However, Julian noted that this can vary depending on patient characteristics, with greater recruitment more commonly observed in larger patients and during monopolar ablation.

The conversation also highlighted an important practical consideration for high-volume programmes, where procedural workflow and resource availability may influence sedation strategy.

This continuation of the live case further explores the complexity of substrate-guided AF ablation in a patient with advanced atrial disease.

As mapping of the posterior wall progresses, the discussion shifts from identifying abnormal signals to determining the most appropriate strategy: should ablation remain anatomically driven, or should lesion delivery be tailored to electrogram characteristics in real time?

The case also highlights an important procedural consideration during posterior wall ablation, preserving left atrial appendage conduction while modifying complex substrate.
