Atrial tachycardias resulting from recipient-to-donor atrio-atrial conduction after orthotopic heart transplantation are difficult to treat. We present two patients in whom atrial tachycardia originating in the recipient heart were successfully treated by radiofrequency ablation guided by electroanatomical CARTO mapping system. These cases illustrate that such atrial tachycardia are curable by radiofrequency ablation. Electroanatomical CARTO mapping is useful in identifying the site of origin of the tachycardia and the atrio-atrial conduction sites.
原位心脏移植后因受体至供体心房-心房传导导致的房性心动过速难以治疗。我们报告了两名患者，其起源于受体心脏的房性心动过速通过电解剖CARTO标测系统引导下的射频消融成功治疗。这些病例表明，此类房性心动过速可通过射频消融治愈。电解剖CARTO标测有助于识别心动过速的起源部位和心房-心房传导部位。
