"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

"Your book [Beat Your A-Fib] is the quintessential most important guide not only for the individual experiencing atrial fibrillation and his family, but also for primary physicians, and cardiologists."

Jane-Alexandra Krehbiel, nurse, blogger and author "Rational Preparedness: A Primer to Preparedness"


"Steve Ryan's summaries of the Boston A-Fib Symposium are terrific. Steve has the ability to synthesize and communicate accurately in clear and simple terms the essence of complex subjects. This is an exceptional skill and a great service to patients with atrial fibrillation."

Dr. Jeremy Ruskin of Mass. General Hospital and Harvard Medical School

"I love your [A-fib.com] website, Patti and Steve! An excellent resource for anybody seeking credible science on atrial fibrillation plus compelling real-life stories from others living with A-Fib. Congratulations…"

Carolyn Thomas, blogger and heart attack survivor; MyHeartSisters.org

"Steve, your website was so helpful. Thank you! After two ablations I am now A-fib free. You are a great help to a lot of people, keep up the good work."

Terry Traver, former A-Fib patient

"If you want to do some research on AF go to A-Fib.com by Steve Ryan, this site was a big help to me, and helped me be free of AF."

Roy Salmon Patient, A-Fib Free; pacemakerclub.com, Sept. 2013

CryoBalloon Ablation Study: 30% of Patients Required RF to Achieve Isolation

CryoBalloon ablation is very effective. But for the best results, you want an EP who is not only experienced with CryoBalloon, but also, when needed, can use RF to map and isolate non-PV triggers.

A recent, but limited study of about 75 paroxysmal A-Fib patients undergoing their first CryoBalloon ablation, found about 30% required the additional use of RF focal lesions to achieve isolation (to restore normal sinus rhythm).

When selecting an EP, be cautious. With the advent of CryoBalloon ablation, some EPs with little or no expertise with RF ablations are now doing CryoBalloon ablations because they’re easier. Stay away from EPs who only do CryoBalloon ablation.

Most experienced EPs who have switched from RF to CryoBalloon ablation have the ability, skill and experience to use focal point RF as needed to make you A-Fib free during your CryoBalloon ablation.

Seek out these experienced EPs by asking:

 “What do you do if I’m still in A-Fib after you do the CryoBalloon ablation? Will you use RF focal lesions to achieve isolation?”
