在窦性心律患者中，左心房形成血栓是罕见的。在3例广泛的心脏淀粉样变性患者中，经胸超声心动图显示在窦性心律时，大心房血栓位于或突出于左心房。多普勒检查显示二尖瓣血流无A波。严重的心房和心室淀粉样蛋白浸润可导致机械性心房静止并形成血栓。这些发现提示严重的心脏淀粉样变性患者在心房功能受损时可能需要抗凝治疗。
Thrombus formation in the left atrium is rare in patients in sinus rhythm. In three patients with extensive cardiac amyloidosis transthoracic echocardiography showed large atrial thrombi in or protruding into the body of the left atrium during sinus rhythm. Doppler studies showed no A wave on mitral inflow. Severe atrial and ventricular infiltration by amyloid may have resulted in mechanical atrial standstill with resultant thrombus formation. These findings suggest that patients with severe cardiac amyloidosis may require anticoagulation when atrial function is impaired.
