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,

"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

Medtronic multielectrode ablation catheter

Multielectrode RF Ablation Catheters

These circular and mesh array shaped catheters are also probably years away from FDA approval. Like balloon catheters they can fit into a pulmonary vein opening and isolate the opening in two or more passes.

These catheters also offer ablation at specific poles to produce pin-point ablation of A-Fib spots in the heart. Currently none of the versions offer internal or external irrigation. (Most RF catheter ablation today uses open irrigation to cool the catheter tip, which allows more energy to be delivered without the limitation of overheating the catheter tip.) (posted 2011)
