Voltage mapping as a method of left atrial fibrosis evaluation

Aim: This pilot study is designed to better understand the mechanisms of development and control of atrial fibrillation. Methods: The correlation between fibrosis index (FI), which was calculated intraoperatively with special software, and clinical and instrumental data was analyzed. Also evaluated were FI values as compared to AF catheter ablation outcomes. Results: Voltage mapping may be considered as a possible alternative to MRI examination and in some cases it is more informative. Conclusion: It was found out that the preliminary results received are a good start for planning a large-scale study in this area related to assessment of the predicative and practical value of the fibrosis index.
