Introduction: Advanced mapping methods for atrial fibrillation (AF) have previously suffered from poor spatiotemporal stability. Electrographic flow (EGF) mapping is a novel technique using computer vision and optical flow smoothing algorithms to avoid this issue.

The aim of this first-in-man Case report is to demonstrate the spatiotemporal stability and long-term reproducibility of a putative AF source in a patient suffering from long-standing persistent AF associated with hypertrophic cardiomyopathy, by comparing EGF maps recorded 18 months apart.
