In a series of 18 patients with atrial myxoma (16 left, 2 right) the tumors were consistently identified by right ventriculography and generally visualized by left ventriculography in patients with left atrial myxoma examined owing to concomitant mitral insufficiency caused by tumor invasion at the site of mitral valve closure. Echocardiography was suited to early diagnosis of suggested tumor. Pseudoaneurysms in the cerebral and coronary arteries, apparently caused by myxomatous emboli with weakening of vessel lumen, were noted in several patients; therefore, selective coronary and cerebral arteriography should be performed preoperatively in patients with symptoms of thromboembolism. We stress that echocardiography should be performed routinely after surgery to disclose recurrences, while arteriographic control studies should be added in cases with vascular anomalies seen preoperatively.
在一组18例心房黏液瘤患者中（16例位于左心房，2例位于右心房），通过右心室造影可始终明确肿瘤位置，对于因肿瘤侵犯二尖瓣关闭部位导致二尖瓣反流而接受检查的左心房黏液瘤患者，左心室造影通常也能显示肿瘤。超声心动图适合于早期诊断疑似肿瘤。在数例患者中发现了脑动脉和冠状动脉假性动脉瘤，显然是由黏液瘤栓子导致血管腔变弱引起的；因此，有血栓栓塞症状的患者术前应进行选择性冠状动脉和脑血管造影。我们强调，术后应常规进行超声心动图检查以发现复发情况，而术前有血管异常的病例应增加动脉造影对照检查。
