Researching Improvements in Ablation Treatment for Atrial Fibrillation


Sanjiv M. Narayan, MD, PhD, is a cardiologist who serves as a professor of medicine and the director of the Stanford Arrhythmia Center at Stanford University. Throughout his career, Dr. Sanjiv Narayan has been a part of numerous research teams that study various aspects of the diagnosis and treatment of atrial fibrillation.

Dr. Narayan and his team recently conducted a study titled, “Secular trends in the success rate of catheter ablation for atrial fibrillation: The SMASH-AF cohort,” with the purpose of examining the evolution of ablation techniques for the treatment of atrial fibrillation. Ablation is the scarring or destruction of heart tissue that sends the abnormal electrical signals that cause atrial fibrillation.

Researchers examined more than 16 years of records (180 studies total) in several public databases. The researchers found that, overall, improvements in ablation techniques for atrial fibrillation have been small but steady. Researchers say these findings indicate that major breakthroughs in atrial fibrillation treatment may have to come from advances in technology or from new ways of thinking about mechanisms of AF in addition to the pulmonary veins.

Domestic and Global Atrial Fibrillation Market to Keep Growing

For more than two decades, Sanjiv M. Narayan, MD, PhD, has been working in the medical field. With postdoctoral training in neurology, electrophysiology, and cardiology, Dr. Sanjiv M. Narayan has spent much of his career serving as a cardiologist and teaching cardiology topics at schools such as Stanford University and UC San Diego. Dr. Narayan is particularly interested in atrial fibrillation, a major health problem around the world.

According to a report from Global Market Insights, the atrial fibrillation market in the United States is the largest in the world. By 2025, the market is expected to expand at a compound annual growth rate of nearly 14 percent.

Experts expect this growth to occur steadily over the forecast period because of the adoption of modern healthcare infrastructure in the US along with an increasing number of new devices that address atrial fibrillation and the growing US geriatric population. Global Market Insights also noted that the global atrial fibrillation market will also increase for many of the same reasons. The global market is expected to surpass $12.5 billion by 2025.
