A 61-year-old man presented with recurrent ventricular tachycardia (left bundle branch block morphology, superior axis). Magnetic resonance imaging (Fig. 1) and contrast-enhanced transthoracic echocardiography (Fig. 2) demonstrated an ill-defined mass in the right heart along the free wall of the right atrium, involving the tricuspid valve and extending into the right ventricle. Extensive investigation showed no evidence of extra-cardiac involvement and a tissue diagnosis was recommended. Accordingly, we elected to proceed to myocardial biopsy and, to facilitate accurate tissue localisation, we performed the procedure under guidance with intracardiac echocardiography.
一名61岁男性因反复发作室性心动过速（左束支传导阻滞形态，电轴上偏）前来就诊。磁共振成像（图1）和经胸超声心动图造影（图2）显示右心沿右心房游离壁有一界限不清的肿块，累及三尖瓣并延伸至右心室。全面检查未发现心外受累证据，建议进行组织诊断。因此，我们决定进行心肌活检，为便于准确的组织定位，我们在心脏内超声引导下进行了该操作。
