"Neovascularity" in the region of the left atrial appendage was demonstrated by coronary arteriography preoperatively in five patients with mitral valve disease and was attributed to the presence of thrombus in the left atrium. Subsequently, they underwent surgery, but thorough inspection of the left atrium did not reveal thrombus in any of the five patients. The presence of neovascularity without apparent thrombosis or false detection may be a result of tissue reaction and organization in an effort to resorb the thrombus.
五例二尖瓣疾病患者术前经冠状动脉造影显示左心耳区域存在“新生血管形成”，并归因于左心房内血栓的存在。随后，他们接受了手术，但对五例患者的左心房进行彻底检查后均未发现血栓。在没有明显血栓形成或误诊的情况下出现新生血管形成，可能是组织为吸收血栓而发生反应和机化的结果。
