Tug tests for Watchman! ICE is invaluable for assessment of tissue contact with the device. Third example done with 2D ICE shows minimal apposition on ridge and was repositioned. Other two images are Nuvison. #EPeeps #cardiotwitter

Functional phenomena predict recurrences of #AtrialFibrillation— finally on-line #HeartRhythmJ! One of our key discoveries is that many of these functional phenomena have normal bipolar voltage and are strongly linked to extracardiac structures (aorta and esophagus). Link

Open window technique to map this beautiful left lateral pathway. #curativeEP Apoor Patel Kandace Branham, CEPS

•Conduction System Pacing Optimized Therapy (CSPOT) •This rather complex acute hemodynamic study revealed incremental benefit of LOT-CRT in patients with deep septal pacing (LB capture not achieved) with a paced QRS>170 ms. Thank you to all collaborators •Marek Jastrzębski

Yesterday's FUNCTIONAL DSP case. F-DSP concept is not a licence to accept any ugly paced QRS. 1) proof of LBB capture or LVSP position is required, 2) should do something more! #Epeeps Zachary Whinnett Óscar Cano Margarida Pujol Lopez Kevin Vernooy micogriecomd Jacqueline Joza Pugal Vijayaraman

Master the Vein of Marshall. This step by step guide details a precise, reproducible approach to ethanol infusion to improve outcomes in persistent AF and enhance mitral isthmus block. doi.org/10.1111/jce.16… Apoor Patel Miguel Valderrabano #Epeeps #Afib #CardioTwitter

Grateful for the opportunity BostonSci Cardiology to teach about conduction system pacing—and for the new friends made along the way. Cheers to learning, connecting, and growing together #LBBAP #MedEd #EPeeps Kevin Trulock Apoor Patel Gaurav A. Upadhyay

Excited to share our multicenter study from Houston Methodist: Pulsed field ablation led to lower 30-day readmissions and higher same-day discharge vs RF ablation for AF. Important implications for quality and cost. #CardioTwitter #EPeeps heartrhythmjournal.com/article/S1547-…

Great experience with Nuvision Nav and Varipulse! Imaging quality was exceptional and love the ability to accurately assess catheter contact with multiple imaging planes. Nice catheter design and minimal manipulation needed to obtain views. #AFib #Epeeps #NuvisionNav #4DICE

NEW from Heart Rhythm TV x CardioNerds! In the fifth episode of our EP Spotlight series, Colin Blumenthal, MD MS sits down with Apoor Patel to discuss Pulsed-Field Ablation of the Mitral Isthmus, focusing on transmurality and autonomic effects validated by Vein of Marshall recordings.
