Doctors & patients are saying about 'Beat Your A-Fib'...


"If I had [your book] 10 years ago, it would have saved me 8 years of hell.”

Roy Salmon, Patient, A-Fib Free,
Adelaide, Australia

"This book is incredibly complete and easy-to-understand for anybody. I certainly recommend it for patients who want to know more about atrial fibrillation than what they will learn from doctors...."

Pierre Jaïs, M.D. Professor of Cardiology, Haut-Lévêque Hospital, Bordeaux, France

"Dear Steve, I saw a patient this morning with your book [in hand] and highlights throughout. She loves it and finds it very useful to help her in dealing with atrial fibrillation."

Dr. Wilber Su,
Cavanaugh Heart Center, 
Phoenix, AZ

"...masterful. You managed to combine an encyclopedic compilation of information with the simplicity of presentation that enhances the delivery of the information to the reader. This is not an easy thing to do, but you have been very, very successful at it."

Ira David Levin, heart patient, 
Rome, Italy

"Within the pages of Beat Your A-Fib, Dr. Steve Ryan, PhD, provides a comprehensive guide for persons seeking to find a cure for their Atrial Fibrillation."

Walter Kerwin, MD, Cedars-Sinai Medical Center, Los Angeles, CA


2020 AF Symposium: 5 Abstracts on Pulsed Field Ablation

The 2020 AF Symposium abstracts are one-page descriptions of A-Fib research, both published or unpublished. The abstracts are supplemental to the Symposium live presentations, panels discussions and spotlight sessions. This year the printed digest contained 55 abstracts. I choose only a few to summarize.

My Summaries of Select PFA Abstracts

Pulsed Field Ablation (PFA) was the single most important topic at this year’s Symposium. I summarized five of the PFA abstracts of most interest to A-Fib patients.

Lesion Durability and Safety Outcomes of Pulsed Field Ablation
The durability of PFA lesions is the focus of Dr. Vivek Reddy’s abstract. His research study followed 113 patients who each received a PFA ablation.

Pulsed Field Ablation with CTI Lesions Terminates Flutter in a Small Study
The use of Pulsed Field Ablation (PFA) may significantly improve CTI ablation lesions to block the Flutter signal. (CTI: Cavo-Tricuspid Isthmus)

Durability of Pulsed Field Ablation Isolation Over Time: Preliminary Study
Pulsed Field Ablation (PFA) is a new treatment. This study asked the question of whether PFA electrical isolation (lesions) regresses over time.

Pulsed Field Ablation vs RF Ablation: A Study in Swine 
PFA is “tissue-specific”. This study tested if surrounding non-heart tissue (the esophagus) would be affected. PFA ablation was compared to RF ablation. Swine (pigs) were used so tissue could be dissected and examined.

Using MRI to Check Pulsed Field Ablations (PFA)
Normally, during a RF or cryo ablation, doctors move the esophagus as far away as possible from where they are ablating. In this study they took no such precautions.
