"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

Emerging Technology: The Cyberknife & Radiosurgery

by Steve S. Ryan, PhD

A new ablation technology, radiosurgery, used initially in the field of oncology (on cancerous tumors), is minimally invasive, and provides accurate placement of beam energy that is guided by imaging.

This technology may have inherent advantages over catheter energy delivery, which relies on perfect tissue contact for placement of continuous lesions.

Using 3-D treatment planning software and technology, the energy delivery is highly focused so as to minimize any possible long term radiation effect on other organs nearby. Radiosurgery can reliably control and predict lesion size for an individual patient’s anatomy.

Radiosurgery application for treatment of arrhythmia is in pre-clinical studies. Radiosurgery technologies and enabling software have been developed by Accuray Inc. (Cyberknife), CyberHeart Inc. and CardioPlan.

Editor’s Comments:
The concept of this non to minimally invasive energy delivery is intriguing. Though there are many obstacles and a possibly huge learning curve to applying Radiosurgery to the treatment of A-Fib, the potential is incredible! Imagine a completely non-invasive procedure to replace catheter ablation and surgery! We wish CyberHeart the best and will continue to follow their progress.
