本例为前一张照片的放大图，可见心外膜的表面有小而黄*色的针尖状微脓肿。微脓肿可能在脓毒败血症患者中发生。他们也可能表现为冠脉外的栓塞，引起栓塞的栓子来自感染性心内膜炎的赘生物。
This magnification of the preceding photograph shows the small yellowish pinpoint microabscesses on the epicardial surface. Microabscesses may appear in persons who are septic. They may also represent emboli from an infective endocarditis in which small portions of a vegetation have embolized out the coronary arteries.
