2022 AF Symposium: Calculating Left Atrium Wall Thickness

Dr. Saman Nazarian
Spotlight Sessions feature products or devices still in development or not yet FDA approved. They give us a glimpse into the future of A-Fib treatments. This year 17 Spotlight products and treatments were presented in 5 minute talks.
In this very short report from the 2022 AF Symposium, I summarize a 5-minute Spotlight session: “Personalization AF Ablation Based on CT Wall Thickness”. Dr. Saman Nazarian, U of Penn, talks about use of Computerized Tomography (CT) to assist during a catheter ablation.
The Issue: The left atrium wall thickness varies from 1 mm to over 5 mm in the roof area. If one applies too much RF ablation power to a thin wall, this can produce steam pops, esophagus damage, or phrenic nerve damage. If too little RF energy is applied to thicker left atrium wall areas, this can lead to Pulmonary Veins (PV) reconnection….to continue reading, go to my very short report.
