Insights
Two-dimensional echocardiography effectively identified left atrial thrombi in patients with mitral valve disease and neurological symptoms. This imaging technique aids in diagnosing thrombus sources for cerebrovascular events and managing cardiac conditions.
Area of Science:
- Cardiology
- Neurology
- Diagnostic Imaging
Background:
- Mitral valve disease can predispose patients to thromboembolic events, including cerebrovascular emboli.
- Neurological symptoms in patients with cardiac disease warrant investigation for potential cardiac sources of embolism.
- Echocardiography is a key non-invasive tool for cardiac assessment.
Observation:
- Three patients with mitral valve disease and neurological symptoms were evaluated using two-dimensional echocardiography.
- Left atrial thrombi were visualized in all three patients.
- In one patient, a ball-valve thrombus causing syncope was detected, while in two others, thrombi were likely sources of prior cerebrovascular events.
Findings:
- Two-dimensional echocardiography accurately depicted the size and position of left atrial thrombi, surpassing M-mode echocardiography.
- Echocardiographic findings were corroborated by anatomical and histological data.
- The study highlights the diagnostic utility of ultrasound in identifying cardiac thrombi.
Implications:
- Two-dimensional echocardiography is recommended for patients with neurological symptoms and suspected cardiac disease.
- Early detection of left atrial thrombi can prevent cerebrovascular events.
- Ultrasound imaging plays a crucial role in the management of patients with complex cardiac conditions and embolic risks.
Abstract:
Left atrial thrombi were shown by two-dimensional echocardiography in three patients with mitral valve disease and neurological symptoms. In two patients the atrial thrombi had probably been the source of a previous cerebrovascular embolus. In the third, two-dimensional echocardiography detected the development of a recent ball-valve thrombus in the left atrial cavity, which caused intermittent obstruction and syncope. Echocardiographic findings were correlated with anatomical and histological data in all three patients. The spatial orientation provided by the multiple imaging planes of two-dimensional echocardiography permitted correct estimates of the size and position of the thrombus, and this mode was superior to the standard M-mode technique for non-invasive imaging of thrombus. Despite limitations of technique and resolution, the information provided by ultrasound can be extremely helpful in the management of patients. Ultrasonic screening (particularly the two-dimensional mode) is to be recommended in patients with neurological symptoms and clinical evidence of cardiac disease or arrhythmia.
