Background: The range of elevation of troponin I (tI) that is within expected limits from left atrial radiofrequency ablation for atrial fibrillation (AF) is not well described, though such information may be of clinical value.
Objectives: Identify the expected range of tI values post-atrial fibrillation (AF) ablation.
Methods: 31 patients undergoing AF ablation had a single tI level drawn the day following the procedure. Clinical variables were also collected, such as ablation type and radiofrequency (RF) time.
Results: Paroxysmal AF was present in 23 patients, and 8 had chronic AF. The average RF time was 2627.8 …
