How close can PFA be delivered to the coronary arteries without causing coronary spasm? #PFA @HRSonline @PrashSanders @EPentraining @MehakDhande @aalahmadmd @BorisSchmidt5 @natale_md

PFA is emerging as a tissue-selective technology; however, a large clinical series showed the incidence of reversible phrenic nerve palsy. There is still a lot to learn about #PFA @HRSonline @EPentraining @PrashSanders @MehakDhande @aalahmadmd @natale_md

Tissue proximity is necessary to achieve deep and durable lesions with #PFA. How to determine catheter-tissue proximity when using PFA? @HRSonline @PrashSanders @EPentraining @MehakDhande @KTamirisaMD @aalahmadmd @natale_md

@HRSonline Wave polarity is important in lesion formation with #PFA @aalahmadmd @PrashSanders @natale_md

The non-conducted atrial activation is at the tail end of the T wave (arrows in the magnified ECG)

Thought provoking His-SYNC trial results presented @HRSonline #HRS2019 @PrashSanders @gopi_gdanda1 @MdHuang @Hisdoc1 Fascinating study despite small number of participants and high rate of crossovers

Nice presentation by @DH_Lau at AF summit on importance of aggressive risk factor modification in atrial fibrillation @HRSonline @PrashSanders
