Left atrial myxomas may present with signs of mitral valve obstruction, embolic phenomena or systemic disease. The diagnosis is suspected on clinical grounds and confirmed by angiocardiography. However, the tumor may be unexpectedly discovered on surgical exploration. Once the diagnosis is established, operation, using cardiopulmonary bypass, should be done promptly. A coexisting valvular lesion should be looked for. Complete cure may be expected, especially if the involved atrial septum is excised and repaired by patch replacement.
左心房黏液瘤可能表现为二尖瓣梗阻、栓塞现象或全身性疾病的体征。根据临床情况怀疑诊断,并通过心血管造影术确诊。然而,肿瘤可能在手术探查时意外发现。一旦确诊,应立即使用体外循环进行手术。应寻找并存的瓣膜病变。有望实现完全治愈,尤其是当切除受累的房间隔并用补片置换进行修复时。
