Nine patients with atrial myxoma in whom selective coronary arteriography had been performed were studied. The angiographic sign of 'tumour vascularity' was found to be present in three patients with highly vascularized atrial myxoma. The clinical significance of the angiographic sign is unknown although highly vascularized myxomata appear to have a greater propensity to bleeding into the tumour, resulting in an acute worsening of clinical symptoms. The angiographic sign of 'tumour vascularity' is not specific but useful to complement the diagnosis of an atrial myxoma. The indication for selective coronary arteriography in patients with atrial myxoma remains the detection of coronary artery disease, thus concomitant coronary artery bypass surgery could be planned preoperatively.
对9例曾接受选择性冠状动脉造影的心房黏液瘤患者进行了研究。在3例血管高度丰富的心房黏液瘤患者中发现了“肿瘤血管形成”的血管造影征象。尽管血管高度丰富的黏液瘤似乎更易发生肿瘤内出血，导致临床症状急性恶化，但该血管造影征象的临床意义尚不清楚。“肿瘤血管形成”的血管造影征象并不具有特异性，但有助于辅助心房黏液瘤的诊断。心房黏液瘤患者进行选择性冠状动脉造影的目的仍然是检测冠状动脉疾病，从而能够在术前规划同期冠状动脉搭桥手术。
