"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

Considering a Catheter Ablation? Know Complication Rates When Choosing Your Doctor

Considering a Catheter Ablation for your atrial fibrillation? Know Complication Rates When Choosing Your Doctor

Complication Rates

by Steve S. Ryan, PhD, October 20, 2014

Considering a Catheter Ablation for your Atrial Fibrillation? You’d best learn who has the lowest/highest complication rates before scheduling your Pulmonary Veins Ablation/Isolation (PVI). In his 2014 BAFS presentation, Dr. David Keane,1 of St. Vincent’s University Hospital, Dublin Ireland, presented important research data for patients considering a catheter ablation: The biggest predictor of in-hospital complications was A-Fib ablation operator volume of less than 25 per year.2

Complications highest with low-volume doctors

This makes sense. A doctor performing a small number of Pulmonary Veins Ablation/Isolations (PVIs) a year may not have enough practice to develop and maintain proficiency in a procedure that is extremely operator-skill dependent; and in fact, may never develop the experience necessary for proficiency. The cardiology community agrees. From the Clinical Competency Statement by the ACC/AHA/ACP: “It is recommended that physicians who perform ablations maintain a [minimum] volume of 20 to 50 ablations/year.”3

The biggest predictor of in-hospital complications…was operator volume of less than 25 A-Fib ablation per year.

Shocking: Most Ablation by the Least Proficient

A more surprising research finding was that “more than 81% of…A-Fib ablation procedures in the US were performed by operators with an A-Fib volume of less than 25 per year.” This astounding statistic is a wake-up call for all A-Fib patients. The vast majority of A-Fib ablations are being performed by operators who are probably the least proficient and certainly have the highest complication rates.

Good News: Complications rate is decreasing

On the brighter side, Dr. Keane’s data showed that as A-Fib ablation techniques and experience have improved, the catheter-related complication rate decreased significantly from nearly 7% in 2002 to less than 2% in 2010. During the same period, the number of ablations had more than tripled.4(As a point of reference, the complication rate of the common appendectomy is 18%.)

What this means to A-Fib Patients

As A-Fib patients, we have to make every effort to be treated by high volume centers and operators. In general, high volume doctors are performing so many A-Fib ablations because they’re good at it and highly successful, with lower complication rates. So, you may ask, how can I find out how many ablations my EP does? Right now all you can do is call EP offices and ask how many PVIs they do per year.

On the horizon: Ideally, a more verifiable (and less socially awkward) method would be to have a list of all EPs in your state and how many PVIs they do each year. Such a database would be based on Medicare data.
I intend to build this database and add it to “Steve’s Lists”. (It will take me some time to make this happen as I am a “one man band”, but we will post by state as each is put online. Check ‘Steve’s Lists’ in a few months for our first posts.)

As A-Fib patients, we have to make every effort to be treated by high volume centers and operators.

Disclosure: In October 2014, A-Fib.com received a “no strings attached” charitable grant from Medtronic to create a database from Medicare data, organized by US state, of EPs with their yearly volume of PVIs. We will publish this database on A-Fib.com as a free service to our readers.
