Are you considering an ablation? Have you explored the clinical literature? What does it mean and what do you really need to know?
Most catheter ablation clinical trials for atrial fibrillation (Afib or AF) focus on freedom from any atrial AF episodes lasting 30 seconds or longer during the 12 months after ablation. Success rates in clinical studies range from 59-89%, likely related to the intensity of ECG monitoring.1
You also may need to read deeper to find the data that matters to you. Quality of life improvement, symptom reduction and AF burden (percentage of time in AF) tend to be secondary data points measured in clinical trials.
The recently published CIRCA-DOSE trial shows a 99% reduction in AF burden after ablation compared to AF burden a minimum of one month before ablation.2 This trial used the most rigorous form of ECG monitoring by using the REVEAL LINQ insertable cardiac monitor with each patient before and after ablation.See Trial Results
