Abstract

Serial echocardiographic changes and angiographic correlation are presented in a patient with multiple pulmonary emboli. Interval development of right ventricular dilatation and paradoxical septal motion coincided with a clinical event which was proven angiographically to represent pulmonary thromboembolism. Echocardiographic findings suggested right ventricular pressure and/or volume overload. The differential diagnosis of this finding when acute is limited; pulmonary embolism is a prominent consideration. Echocardiography performed after the patient received anticoagulant therapy showed a complete return to normal. Echocardiographic evidence of right ventricular overload, particularly when acute, may indicate the presence of a pulmonary embolism, and may be clinically useful in selected cases.

摘要

本文介绍了一名患有多发性肺栓塞患者的系列超声心动图变化及其与血管造影的相关性。右心室扩张和室间隔矛盾运动的阶段性发展与一项临床事件同时出现，血管造影证实该事件为肺血栓栓塞。超声心动图结果提示右心室压力和/或容量超负荷。急性情况下这一发现的鉴别诊断范围有限；肺栓塞是一个重要的考虑因素。患者接受抗凝治疗后进行的超声心动图检查显示完全恢复正常。右心室超负荷的超声心动图证据，尤其是急性时，可能提示存在肺栓塞，在某些病例中可能具有临床应用价值。
