How can multiple data points help optimise catheter position during PVI?

In this RIO Global 2026 live case, Julian Chun brings together live fluoroscopy, 3D mapping, angiography and electrograms to assess positioning within the left superior pulmonary vein.

As the catheter position is adjusted, Julian Chun demonstrates the corresponding change in electrogram quality and amplitude, using the available information to assess and improve contact before progressing with ablation.

Julian Chun and Andrea Urbani perform the case, with Chair Devi Nair and panellists Ignacio García Bolao, Sebastian Feickert and Patrick Lugenbiel joining the discussion.

What does Roland Tilz value in the latest generation of LAA closure technology?

During this RIO Global 2026 live case, Roland Tilz shares his experience with Amulet™ 360, highlighting the features he values when navigating different LAA anatomies, achieving sealing and positioning the device within the appendage.

Roland Tilz also discusses how the design has evolved from the previous generation, including changes to the anchor profile.

Joining the discussion are Chair Devi Nair and panellists Claudio Tondo, Ivo Roca-Luque, Boris Schmidt and Sri Sundaram.

What should operators consider when phrenic nerve stimulation occurs during PFA?

In Durable PFA Explained: From Balloon-in-Basket Design to Live AF Practice at RIO Global 2026, Dr Daniel Rodriguez Muñoz demonstrates balloon catheter manipulation and ablation delivery during a live case from 12 de Octubre University Hospital, Madrid.

The expert panel discusses phrenic nerve pacing and the diaphragmatic contractions observed during PFA, particularly when treating the right superior pulmonary vein.

Dr Rodriguez Muñoz shares his experience of comparing these contractions with cryoablation, including the implications for patient movement and lighter sedation strategies.

The case offers a practical perspective on catheter positioning, phrenic nerve capture and procedural workflow during PFA.

Assessing coronary venous anatomy during complex VT ablation.

In VT Mapping and Ablation in Clinical Practice at RIO Global 2026, Dr Roderick Tung discusses the challenges of navigating the coronary venous system during a live case from the University of Arizona College of Medicine.

Dr Ammar Killu raises the possibility of using collateral venous pathways to reach the target region, prompting further discussion of the middle cardiac vein and alternative access routes.

The panel also considers whether an apparent distal venous occlusion could represent dissection following previous catheter manipulation.

The case highlights the importance of interpreting venographic findings and adapting procedural strategies when access is limited.

Mapping complex ventricular tachycardia (VT) with the Sphere-9 catheter.

In Live Case & Discussion | Navigating Complex VT: An All-in-One Mapping and Ablation Case with Sphere-9 at Rhythm Interventions Online (RIO) Global 2026, Dr Reza Wakili demonstrates real-time left ventricular substrate mapping during a live procedure from University Hospital Frankfurt, Germany.

Dr Wakili discusses the mapping capabilities of Sphere-9, highlighting catheter manoeuvrability, intracardiac signal quality and the identification of local abnormal ventricular activities (LAVAs) during substrate assessment.

The case explores the team's approach to left ventricular access, beginning with transseptal access and considering a retrograde aortic approach when required.

Dr Wakili also demonstrates rapid electroanatomical mapping, using different anatomical views and intracardiac electrograms to assess the ventricular substrate.

Chaired by Richard Schilling, with expert discussion from Verena Tscholl, A***n Sultan, Helmut Pürerfellner, Andrea Sarkozy and Roderick Tung, the case provides practical insight into mapping strategies for complex VT ablation.

Optimising WATCHMAN FLX™ Pro positioning during left atrial appendage (LAA) closure.

In Live Case & Discussion | Concomitant Ablate and Close: Impact to Practice at Rhythm Interventions Online (RIO) Global 2026, Dr Christian-Hendrik Heeger demonstrates WATCHMAN FLX™ Pro device positioning during a live procedure from Asklepios Klinik Altona, Hamburg.

The case highlights the importance of device orientation within the appendage, with Dr Heeger assessing proximal markers and positioning relative to the left circumflex artery.

Chair Dr Devi Nair provides real-time guidance on sheath manipulation, including counterclockwise rotation to maintain anterior orientation and adjustments to deployment depth.

The discussion also explores deployment techniques, including the balance between unsheathing and forward pressure to optimise device positioning.

Building a clearer picture of the VT substrate.

In this RIO Global 2026 live case, Reza Wakili introduces inHEART CT imaging alongside the team’s electroanatomical map.

The imaging reveals scar distribution consistent with their mapping findings, opening up a wider discussion on how CT can provide complementary information when evaluating a complex VT substrate.

Watch the case with Richard Schilling, Verena Tscholl, A***n Sultan, Helmut Pürerfellner, Andrea Sarkozy and Roderick Tung.

How can catheter rotation help optimise coverage during PFA?

In this RIO 2025 live case, the team demonstrates how the horseshoe configuration sits in relation to the catheter shaft and highlights what happens when the catheter is rotated inside the sheath.

See how rotating around the shaft with the PulseSelect™ catheter can cover a larger area, offering a practical look at catheter positioning during PFA.

How do you optimise TPI during pulmonary vein isolation?

In this live case from RIO 2025, the team assesses TPI across the electrodes, aiming for 12 out of 12 where possible before moving from the posterior wall to target a small remaining area.

Watch as they deliver an additional application, use the steerable sheath to refine positioning and then prepare to check whether the area has been entirely ablated.

Chair Richard Schilling was joined by Case Operator Christian Sohns and panel members Devi Nair and Kousik Krishnan.

How do you assess left atrial voltage and optimise catheter positioning during pulsed field ablation (PFA)?

In this RIO Global 2026 live case, Julian Chun and Andrea Urbani (CCB Markus Krankenhaus, Frankfurt, Germany) demonstrate their approach to left atrial assessment and pulmonary vein ablation using the FARAVIEW and FARAWAVE technologies.

Julian Chun reviews the left atrial voltage map, highlighting the preserved posterior wall voltage despite persistent atrial fibrillation (AF). The team then demonstrates catheter positioning in the inferior pulmonary vein, adjusting the configuration based on angiographic dimensions to optimise tissue contact.

Chair Devi Nair is joined by panellists Ignacio García Bolao, Sebastian Feickert and Patrick Lugenbiel for the discussion.
