"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

CardioInsight Technologies

Medtronic Acquires CardioInsight ECVUE Mapping System

Medical technology giant Medtronic has acquired CardioInsight Technologies, developer of the ECVUE mapping and ablation system. CardioInsight will become part of the Medtronic Atrial Fibrillation Solutions business in the Cardiac Rhythm and Heart Failure division.

Mapping and ablation systems are critical to the advancements in catheter ablation techniques and improving A-Fib patient outcomes.

During a standard catheter ablation, doctors use a special mapping catheter that has to be positioned inside the heart to map and identify A-Fib producing spots in the heart.

But the new Noninvasive Electrocardiographic Imaging (ECGI) system does not go inside the heart, but instead uses a vest-like device which a patient wears to image the inside of the heart and to pinpoint sites in the heart producing A-Fib signals.

VIDEO: See the animation of the ECVUE vest technology at the bottom of the CardioInsight page (just wait a second or two for it to load).

The ECVUE system has been in trials with more than 1,400 patients, mostly in Europe, (US clinical trials have been limited). It has also been featured in more than 120 peer reviewed journals and presentations. It’s being very carefully tested and slowly brought to market primarily by Dr. Michel Haissaguerre and the French Bordeaux Group.

What Patients Need To Know

It certainly looks like the ECVUE mapping and ablation system will be a game changer for A-Fib patients, especially for those with persistent A-Fib, usually the hardest to cure. See my 2013 AF Symposium report: Non-Invasive Electrocardiographic Imaging (ECGI).
But it’s been frustrating for patients in the US since the testing is being done at multiple centers in Europe. However, one would expect this would change soon with Medtronic buying CardioInsight.
The careful and deliberate testing and marketing approach of ECVUE contrasts with the introduction of the competing FIRM system from Topera Medical. Though FIRM was first on the market and has received great PR in many newspapers and media outlets throughout the US, clinical studies have raised performance issues


I predict that the ECVUE mapping and ablation system will soon be predominate throughout the world.
For more about the two competing mapping and ablation systems, see my 2014 AF Symposium article: ECGI vs. FIRM: Direct Comparison, Phase/Waveform Mapping
