This live case explores practical workflow optimisation in pulmonary vein isolation using pulse field ablation, led by Salem Younsi and Jérôme Lacotte.

The discussion focuses on catheter positioning and contact optimisation, including the use of RVOT wire placement to improve stability in selected cases. Fluoroscopic views in RAO and LAO projections are used to assess alignment, while catheter rotation is adjusted to correct septal bias and improve lesion delivery consistency.

The case highlights how small adjustments in wire position, catheter rotation and imaging perspective can directly influence procedural efficiency and contact quality during PVI.

This live case highlights the complexity of Brugada syndrome and epicardial VT mapping, led by Roderick Tung.

A type 1 Brugada pattern is confirmed with 3 mm ST elevation and terminal T-wave inversion. ICE imaging reveals an enlarged RV with mild global hypokinesis and subtle anterior RVOT aneurysmal changes.

Faculty discussion considers the structural overlap between Brugada syndrome and ARVC, noting the phenotypic distinction that polymorphic VT/VF occurs at night in Brugada patients, while ARVC rarely causes such arrhythmias.

A compelling example of integrating ECG, imaging, and structural insights to guide epicardial VT ablation strategy.

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

The workflow emphasises precise septal pe*******on through rapid rotations, with continuous monitoring of ECG morphology in V1, current of injury, and impedance. Lead rotation is used to identify subtle changes in QRS morphology and ensure optimal fixation and electrical capture.

This stepwise approach illustrates how detailed observation of electrical signals, impedance, and morphology guides successful CSP placement and procedural confidence.

Join Julian Chun in this live PFA + LAA closure case using the OLIVE workflow.

Each energy application is monitored for tissue capture, signalled by the iconic PFA sound, and catheter stability is confirmed. Multiple rotations and basket configurations ensure full coverage, while patient movement is minimal. Faculty insights have validated the optimal sequence and number of applications, demonstrating how procedural standardisation improves safety, efficiency and reproducibility in combined AF ablation and LAAO workflows.

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.
