Myocardial calcification is a rare condition, with only a few reports in the literature. For the first time, we report a case of diffuse myocardial calcification who underwent successful catheter ablation for persistent atrial fibrillation (AF). In this case, catheter ablation was recommended due to repeated hospitalization for palpitation and heart failure, but preoperative computed tomography showed massive myocardial calcification. Electroanatomic mapping of the atrium was performed with a Pentaray catheter before ablation, which showed areas of low voltage in the calcified region. As the persistent AF was terminated after circumferential pulmonary vein isolation and posterior wall isolation, and no further ablation was performed. The patient recovered well, with no recurrence of palpitation or heart failure during the one-year follow-up.
心肌钙化是一种罕见病症，文献中仅有少数报道。我们首次报告了一例弥漫性心肌钙化患者，该患者因持续性心房颤动（AF）接受了成功的导管消融治疗。在此病例中，由于因心悸和心力衰竭反复住院，故建议进行导管消融，但术前计算机断层扫描显示存在大量心肌钙化。消融前使用Pentaray导管对心房进行了电解剖标测，结果显示钙化区域存在低电压区。由于在进行环肺静脉隔离和后壁隔离后持续性房颤终止，因此未进行进一步消融。患者恢复良好，在一年的随访期间未出现心悸或心力衰竭复发。
