Fig. 3From: Left atrial wall thickness and its relationship with reconnection after pulmonary vein isolation in patients with atrial fibrillation evaluated using a three-dimensional wall thickness mapAtrial wall thickness of PV antrum. Distribution of AWT grades of overall 1256 ablation segments (a) and ablation segments of each PV antrum (b). -S, superior segment (e.g., LSPV-S, superior segment of LSPV); -A, anterior segment; -P, posterior segment; -C, carina segment; -I, inferior segment. c Distribution of AWT grades. AWT atrial wall thickness, RECON reconnected segments, NR non-reconnected segments. All diagrams were generated by Excel 2016 (Microsoft, Redmond, WA).Back to article page
