𝐂𝐚𝐧 𝐘𝐨𝐧𝐭𝐚𝐫 John Papagiannis Here is that patient referenced above. Strikingly minimal preexcitation in sinus despite extreme tachycardia in a.fib. To your point, degree of preexcitation in sinus does not predict ERP of accessory pathway.

ICE assists in difficult anatomy cases. Subtricuspid retrograde ablation with inverted catheter technique avoids septal tricuspid valve apparatus (in Ebstein it is often adherent to ventricular wall), improving stability and safety.🤓

Jeffrey M Vinocur What led you to bring her to the lab? I wonder how many folks we label inappropriate sinus tachycardia really have an AT

A reminder to *please* follow outpatient potassium (K+) levels in all your patients after increasing diuretic dose, or after permitting extra PRN diuretic use! I've heard of 2 recent cases with sudden death due to K+ 2.0, 2.2 from more diuretic & unmonitored K+ 😥 1 of 2....

Have you ever used the modified Lewis lead configuration to identify atrial activity? An easy and useful tool which is probably not in everyone's toolbox. Check out our case in Circulation VCU Health Pauley Heart Center #ACCFIT #EPeeps

John, MD MUSC Electrophysiology Pasquale Santangeli IMO, the vein is just a route to epicardial signals. Actually better than mapping epicardial surface, as we presented at HRS2024

Fascinating approach some surgeon took to Mustard operation…inferior baffle limb sewn not to Eustachian ridge or tricuspid annulus but down within the IVC as the hepatic veins insert…contemplate that flutter ablation!
