Pathological Findings of Cavotricuspid Isthmus Tissue Eighteen Days after Radiofrequency Catheter Ablation for Typical Atrial Flutter
Abstract
A 75-year-old man with a prior myocardial infarction, who underwent a coronary artery bypass graft, suffered from typical atrial flutter. He underwent a cavotricuspid linear catheter ablation. Eighteen days after the ablation, he suddenly died. A transmural ablation line was created between the inferior vena cava and tricuspid annulus. Transmural loss of the cardiomyocytes and small clusters of coagulative necrosis were observed. Evidence of edema and a patchy hemorrage remained in the extracellular space.
