Pre & post voltage maps from hybrid (surgical epicardial + endocardial) ablation for inappropriate sinus tachycardia. Resting HR: 130 → 70 bpm. Back to work in 4 weeks, living a normal life. 🔗 Read the case: pmc.ncbi.nlm.nih.gov/articles/PMC11… #MedTwitter #Cardiology #HeartRhythm #Ablation

Enjoyed assisting with some workflow and technology improvements in FIH trials of novel Viewflex X ICE catheter from @AbbottCardio -- we performed ablation of PVC from suspected intramural site with RF to septal RVOT and adjacent ASOV. Will be curious to see what @dhakalbish thinks with his @PennEPFellows based ICE approach in trials tomorrow. Contouring of key structures including pap muscles and ASOV shown below: @AMatthews0 @mikelean @Zachkoch13

World First Robotic IST Ablation: Next Level Yesterday, we successfully performed a groundbreaking procedure - the world's first robotic Inappropriate Sinus Tachycardia (IST) ablation. IST is a clinical syndrome that causes an inexplicably high resting heart rate (>100 bpm), leading to debilitating symptoms like palpitations, dyspnea, and dizziness. This condition is often misdiagnosed, especially in women, leaving patients suffering for years.

A world’s first for treating the most common abnormal heart rhythm. Our TactiFlex Ablation Catheter, Sensor Enabled, is now FDA approved, making it a first-of-its-kind treatment option for atrial fibrillation. abbo.tt/3OsPrW3 ISI: abbo.tt/3pTigAX

New EnsiteX NEAR FIELD software for gap identification in AF. Just after left PVs antral ablation, late PV potentials still there. Quick map shows no high frequency EGMs (dark) at posterior aspect inside ablation line (scar 0.04mV) but high freq signals (bright) at upper ridge... local ablation and that was it! #Epeeps

An excerpt from live unstable VT case from PHX >#RIOCongress2022. Our unfiltered & genuine excitement with fellow @DrKatrapati says it all- physiology, intensity, risk/payoff to eradicate VT. Thank you to our patient for their generosity. #ablateVT #ILAM #VTin3D

Nice surprise during an Afib ablation. SVC x 2! Did some great work in the area with circumferential lesions. Discovered because of the size of the CS on ICE! @DrRoderickTung @uazmedphx #EPeeps

Nice Right sided AT today… Pt with frequent episodes of SVT despite medication. Intermediate RP on hospital EKG. Nothing induced with EPS. Bi and tri-germinal PACs with short runs on iso… quickly mapped and localized to posterior RA with HD-Grid. Local egm -35 msec. 1 and done!

Phenomenal signal fidelity possible #OnlywithOT. Site of 1 burn term contained 37% of the TCL and ranged from 0.02-0.07 mV. With its low noise floor, we’re seeing things differently with #EnsiteX. #HDGrid #TCSE #MidAmericaEP

@XavierR_EP @XavierR_EP…Saw this pt last week - 0 VT!! #ablateVT

No lead means we’ll just have to hit the gym that much harder next week 💪🏽

@chris_lewchuk @BrianGoski @KoerberScott No, first burn at exit site was able to terminate!

@Segarspr and @subparsonsmaps using new technology to push the boundaries of what has historically been impossible. Innovative use of Omnipolar Technology for NoREF Mapping of a PW leak in AFib. #AbbottAF #OnlyWithOT #EPeeps

Left Lateral AP retrograde conduction with LA breakout mapped beautifully with omnipolar GRID on EnSiteX @AbbottCardio @uazmedphx

Propagation, illustrating those MDPs captured by #HDGRID

Ischemic VT w/ a figure-8-esque circuit, mapped beautifully by @ambrosepanico

Omnipolar is game-changing for automated ILAM approach. New(L) vs. old(R) auto annotation display without any manual annotation. Yet another localized periaortic VT substrate from LMNA, with diastolic 🍽️ buffet during VT within sinus rhythm deceleration zone. @AbbottCardio

#OmnipolarTechnology showcases a microreentry flutter in a single acquisition. OT EGMs are individually corrected to align to the wavefront providing the true EGM. 3x enhanced point density provides increased specificity to correctly exhibit the entire circuit.
