Left ventricular mural thrombus: two-dimensional echocardiographic diagnosis
Insights
Two-dimensional echocardiography effectively identifies left ventricular thrombus, especially in the apex. This imaging technique proved more accurate than angiography for detecting thrombus in patients with heart conditions.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Left ventricular thrombus is a significant complication of various cardiac conditions.
- Accurate diagnosis is crucial for appropriate management and prevention of embolic events.
Purpose of the Study:
- To describe the echocardiographic and clinical features of left ventricular thrombus.
- To evaluate the accuracy of two-dimensional echocardiography in thrombus detection compared to angiography.
Main Methods:
- Retrospective analysis of 60 patients with echocardiographic evidence of left ventricular thrombus.
- Detailed description of thrombus appearance, location, and association with cardiac diseases.
- Comparison of two-dimensional echocardiography with pathological or surgical confirmation in 14 patients.
Main Results:
- Left ventricular thrombus appeared as intracavitary echoes, often apical, and denser than myocardium.
- Larger thrombi were more frequent in dilated cardiomyopathy than in coronary artery disease or left ventricular aneurysm.
- Apical echocardiographic views were most effective for thrombus visualization.
- Two-dimensional echocardiography demonstrated higher accuracy than angiography in thrombus identification.
Conclusions:
- Two-dimensional echocardiography is a reliable method for diagnosing left ventricular thrombus.
- The technique offers superior accuracy compared to angiography for thrombus detection.
Abstract:
The two-dimensional echocardiographic and clinical features of 60 patients with echocardiographic appearance of left ventricular thrombus are described. Thrombus appeared as intracavitary echoes contiguous with the ventricular wall, most often apical in location and denser than adjacent myocardium. Large thrombi were more commonly seen in dilated cardiomyopathy than in coronary artery disease with segmental wall abnormalities or left ventricular aneurysm. The apical examination was most useful for visualizing thrombus. In 14 patients with pathologic or surgical confirmation, two-dimensional echocardiography was more accurate than angiography in correctly identifying thrombus.
