New research examines how pulse width and pulses per burst impact lesion depth, musculoskeletal stimulation, and incident heating with our #TactiFlex Duo Ablation Catheter, Sensor Enabled.

Andrea Sarkozy explains how the PFA index combines application count, contact force and tissue impedance changes to help predict lesion depth and guide continuous lesion delivery.

A WIN for the Entire LAAO Space! 🏆

The VERITAS 12-month results mark another exciting milestone in the evolution of left atrial appendage occlusion!
Congratulations to the VERITAS investigators and the Abbott team for advancing the field!

New data presented at #APHRS2026 offered a closer look at how physicians and researchers are putting PI/AI into clinical practice across a variety of scenarios for PF and RF ablation with TF Duo.

Thank you to the many researchers moving PF science forward!

[Joe Provost @JoeProvost7]

Today, @MonicaYLo presented "TactiFlex Duo Effectiveness Factors," sharing critical, extensive insights from
FOCALFLEX and FLEXPULSE.

These findings provide a deeper understanding of how procedural strategy & catheter performance may contribute to effective ablation. #APHRS2026

Auburn K Alex McPherson was diagnosed with ulcerative colitis in the spring of 2024 and had his large intestine removed along with part of his colon.

Two years later, he made the game-winning kick to knock off No. 1 Georgia ❤️

Congratulations to @DrSouvikKDas on this fantastic achievement at the VT Symposium!👏Great to see this work highlighting the value of combining CT-derived corridors, lipomatous metaplasia, and functional mapping to improve VT isthmus identification.
Another step forward in bringing cardiac imaging and EP closer together!

Great session from Dr. @RolandTilz on early clinical experience with VT and PVC Ablation with a Dual-Energy (RF/PF) Flexible-Tip Ablation Catheter at #VTSymposium.

Imaging–EGM disagreement
How much to ablate? What is the smallest set to disconnect the relevant channel and preserve myocardium?

[ADAS3D Medical @ADAS3D]

It’s a busy season for heart rhythm care — and we’re excited to be on the road again. We’re heading to #HRC2026 in Birmingham! Join the #ADAS3D team on 11–13 October. Come meet us at Booth 2, bring us a challenging case, and discover how CT and MRI imaging can support VT and AF procedures.

My first VT ablation at Joan XXIII 🎸🔥. 59yo, ischemic cardiopathy with inferior scar. Sustained VT was easily induced, involving a short channel previously identified with LGE-CMR model. Gorgeous mid-diastolic signal were tagged and VT stopped during the first RF application.

[Sri Sundaram @srissundaram]

Thanks for the shout out ! Burnout in medicine is real. Being more efficient during the day without compromising patient care is the way to go. We used MAC rather than GA, got similar acute outcomes and saved 22.7 mins in between cases.

[Aatish Garg @AatishGarg_EP]

First case in Northeast with Tactiflex DUO and what a great case it turned out - epicardial LV summit pvc mapped earliest with EP star epicardially , successfully ablated endocardial with stacked PFA despite being barely on time endocardial.

Understanding lesion visualisation in PFA workflows.

In this clip, Peter Karl Jacobsen discusses how tags and E fields can support lesion placement during PFA procedures.

He highlights that these tools should be used as procedural guides rather than interpreted as absolute markers, recognising that E fields and tags represent impedance-based surrogates of the delivered therapy.

The discussion explores how E field visualisation may provide additional insight into lesion location and help operators assess catheter positioning during ablation.

A practical perspective on interpreting mapping information and integrating visual feedback into PFA workflows.
