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."

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.
