Atrial myxoma is the most common benign tumor of the heart, but its appearance after radiofrequency ablation is very rare. We report a case in which an asymptomatic, rapidly growing cardiac myxoma arose in the left atrium after radiofrequency ablation. Two months after the procedure, cardiovascular magnetic resonance, performed to evaluate the right ventricular anatomy, revealed a 10 × 10-mm mass (assumed to be a thrombus) attached to the patient's left atrial septum. Three months later, transthoracic echocardiography revealed a larger mass, and the patient was diagnosed with myxoma. Two days later, a 20 × 20-mm myxoma weighing 37 g was excised. To our knowledge, the appearance of an atrial myxoma after radiofrequency ablation has been reported only once before. Whether tumor development is related to such ablation or is merely a coincidence is uncertain, but myxomas have developed after other instances of cardiac trauma.
心房黏液瘤是最常见的心脏良性肿瘤，但其在射频消融术后出现的情况非常罕见。我们报告一例无症状、快速生长的心脏黏液瘤在射频消融术后出现在左心房的病例。该手术两个月后，为评估右心室解剖结构进行的心血管磁共振成像显示，一个10×10毫米的肿块（推测为血栓）附着于患者左心房隔膜。三个月后，经胸超声心动图显示肿块增大，患者被诊断为黏液瘤。两天后，一个20×20毫米、重37克的黏液瘤被切除。据我们所知，射频消融术后出现心房黏液瘤此前仅被报道过一次。肿瘤的发生与这种消融是否有关，还是仅仅是巧合尚不确定，但在其他心脏创伤病例后也曾出现过黏液瘤。
