Persistent substrate challenges are on display in this live case with Jérôme Lacotte and Vladimir Manenti.

Despite two RF ablations using contact-force catheters, the pulmonary veins remain connected, highlighting the complexity of AF with low-lying appendages.

Fragmented potentials along the septum and posterior wall activation demonstrate why tailored mapping and careful assessment of local electrograms are critical for effective ablation strategy.

This session showcases how advanced mapping tools guide decisions in real time, especially in challenging anatomical scenarios.

In this live case, Salem Younsi and Jérôme Lacotte demonstrate a streamlined PFA workflow using the Pulse Select system. Over 60% of patients are discharged the same day, illustrating the safety of a minimal yet effective approach.

The team focuses on PVI-only ablation, even in persistent AF, following evidence-based principles and avoiding additional lines where data does not support benefit. With 7–8 cases performed per day, this workflow highlights how structured efficiency and procedural consistency can maintain high-quality outcomes without unnecessary complexity.

In this live case, Jérôme Lacotte and Vladimir Manenti navigate a challenging atrial substrate with complex scarring on the septum.

The team demonstrates how advanced mapping strategies, including vein mode features, allow precise point acquisition while avoiding map distortion from scarred regions. By carefully redefining the reach and activating dedicated algorithms, they optimise coverage between the pulmonary veins and appendage, ensuring a more accurate and actionable map for targeted ablation.

This session highlights the importance of adapting mapping workflows to patient-specific anatomy and prior ablation history.

Michael Lloyd walks through a structured approach to SICD implantation, focusing on pocket preparation and closure techniques.

He demonstrates how to achieve a secure device position without anchoring sutures, using precise muscular closure with a small-gauge, absorbable suture. The closure approximates the serratus to the latissimus dorsi, with a layered technique and overlying glue to maintain pocket integrity.

This session emphasises how careful attention to closure can improve procedural efficiency and device security, highlighting practical tips that every EP should know.

Devi Nair demonstrates the versatility of a multi-electrode array for PVI and linear ablation.

Using the Globe system from Kardium, she navigates to the left superior pulmonary vein, showing how minor adjustments and rotation optimise contact while respecting previously ablated regions like the carina. Post-ablation voltage mapping confirms effective lesion overlap and coverage.

ICE is used primarily for safety assessment rather than navigation, allowing Devi to rely on real-time contact scans for precise electrode selection. Each application lasts approximately 30 seconds, with multiple drive trains ensuring durable ablation.

This session highlights how multi-electrode arrays, combined with careful mapping and contact assessment, can enhance procedural efficiency and safety in AF ablation.

Devi Nair demonstrates dual leadless pacing techniques, guiding the ventricular device implant with ultrasound and intracardiac echo for visualisation.

Access is obtained via ultrasound, and pre-closure ensures procedural safety. The ventricular device is deflected into the right ventricle, with orientation confirmed using RAO and LAO angiography. Devi emphasises septal engagement and the helix mechanism for stable fixation, showcasing how careful imaging and stepwise technique optimise implant accuracy.

This session highlights the precision required in dual leadless pacing and practical strategies to enhance procedural confidence.

In this live case, Nicolas Derval demonstrates a hybrid ablation strategy for persistent AF.

A standard radiofrequency approach is applied to the anterior wall to influence autonomic activity, while electroporation is used on the posterior wall, with real-time monitoring of tissue response.

Extended pulse timing is applied to optimise lesion formation, and subtle procedural effects, such as bronchial response, are noted, highlighting the importance of meticulous planning and patient monitoring during posterior wall ablation.

Domenico Della Rocca shares insights from redo AF ablation procedures, highlighting how lessons from prior cases shape current workflow.

By actively remapping patients and analysing gaps from previous ablations, the team adapts their approach in real time. This session underscores the importance of learning from each procedure to refine lesion delivery and improve outcomes.

Christian Sohns takes us through a streamlined PFA workflow for AF ablation, focusing on precise pulmonary vein isolation.

Throughout the case, careful attention is given to achieving optimal tissue contact (TPI) across all electrodes. Even small gaps along the posterior wall are addressed with additional applications, ensuring complete and durable isolation.

This session highlights how meticulous workflow and incremental adjustments can improve procedural efficiency and lesion quality in real-time AF ablation.

In this live case, Julian Chun continues the WATCHMAN FLX™ Pro deployment, demonstrating how careful adjustment and real-time imaging ensures optimal device positioning.

Using fluoroscopy and TOE, the team tracks the device across the left atrium and the RAFI, confirming correct alignment and adequate compression. The session highlights how careful device development, incremental deployment, and colour-enhanced imaging allow operators to verify minimal leakage and avoid protrusion into the atrium.

This case showcases a meticulous approach to left atrial appendage closure, balancing safety, efficacy, and patient-specific considerations for high bleeding-risk patients.
