There is a strong association of cardiac rhabdomyomas with the Wolff-Parkinson-White syndrome. This report describes the results of investigations in two patients with accessory pathway-mediated AV reciprocating tachycardia coexisting with intracardiac tumors.
Two patients with intracardiac tumors had mapping of the accessory pathway. Echocardiograms obtained in the electrophysiology laboratory while the ablation catheter was at the site of successful radiofrequency ablation demonstrated a close correspondence between the site of intracardiac tumor and the location of the accessory pathway.
These results lend support to the hypothesis that accessory pathways in patients with intracardiac tumors, such as rhabdomyomas, are not typical Kent bundles, but instead are either part of the intracardiac tumor or are closely related to the tumor. Ablation is possible in at least some patients with accessory pathways associated with intracardiac tumors.
心脏横纹肌瘤与预激综合征之间存在密切关联。本报告描述了两名患有旁道介导的房室折返性心动过速并伴有心内肿瘤患者的检查结果。
两名心内肿瘤患者接受了旁道标测。在电生理实验室进行射频消融成功时，消融导管所在位置的超声心动图显示，心内肿瘤部位与旁道位置密切对应。
这些结果支持了这样一种假说，即患有心内肿瘤（如横纹肌瘤）患者的旁道并非典型的肯特束，而是心内肿瘤的一部分或与肿瘤密切相关。至少部分伴有心内肿瘤旁道的患者可行消融治疗。
