Fig. 12. Atrioesophageal fistula in 43-year-old male who underwent catheter ablation of AF.

Electroanatomic map (A) shows multiple ablation points forming antrum ablation line (arrow) for electrical isolation of LSPV just anterior to Eso (arrowhead). Transverse chest CT image (B) shows small air-bubble (arrow) near LSPV. Sagittal reformatting image of chest CT (C) shows air-bubbles (arrow) between ESo (arrowhead) and LA. Fluid-attenuated inversion recovery magnetic resonance image of brain (D) reveals embolic stroke with multiple foci of bright signal intensity in bilateral cerebral hemispheres. Eso = esophagus
