[Abnormal intracavitary dynamic echoes. II. In vivo study]
Insights
Dynamic intracavitary echoes (DIEs) indicate slow blood flow in the heart, often seen in conditions like mitral stenosis or cardiomyopathy. These echoes may be linked to red blood cell aggregation.
Area of Science:
- Cardiology
- Echocardiography
- Hematology
Context:
- Dynamic intracavitary echoes (DIEs) are observed in patients with conditions leading to slow cardiac flow.
- These include mitral stenosis, congestive cardiomyopathy, and left ventricular aneurysm.
- DIEs can suggest regional blood stasis within cardiac chambers.
Purpose:
- To investigate the presence and significance of dynamic intracavitary echoes (DIEs).
- To correlate DIEs with specific cardiac conditions and patient outcomes.
- To explore the potential causes of DIEs, such as red blood cell aggregation.
Summary:
- DIEs were detected in 17 patients across various cardiac conditions, including mitral stenosis, mitral prosthesis, congestive cardiomyopathy, and left ventricular aneurysm.
- DIEs were localized to the left atrium or left ventricle depending on the underlying condition.
- In some cases, DIEs correlated with the presence of thrombi or non-coagulated blood and resolved after intervention.
Impact:
- DIEs can serve as a diagnostic indicator of regional blood stasis in patients with slow cardiac flow.
- Understanding DIEs may improve the diagnosis and management of thromboembolic events in at-risk populations.
- The findings suggest a link between red blood cell aggregation and the occurrence of DIEs.
Unlabelled:
Dynamic intracavitary echoes (DIE's) suggesting regional stasis of blood, were detected in 17 patients (pts) (6 with mitral stenosis, 1 with mitral prosthesis, 5 with congestive cardiomyopathy, 5 with left ventricular aneurysm). DIE's were observed in the left atrium in all pts with mitral stenosis and in the patient with a prosthetic valve, in the left ventricle in the remaining pts. In 5 pts a thrombus was detected in the cardiac chamber in which DIE's were observed. In 4 pts direct inspection (at surgery or autopsy) of the cardiac chamber in which DIE's were detected revealed the presence of non-coagulated blood. All pts with DIE's in the left atrium were in atrial fibrillation. In one case with mitral stenosis DIE's disappeared after commissurotomy.
In Conclusion:
DIE's suggesting regional stasis of blood may be detected in pts with clinical conditions characterized by slow cardiac flow; this phenomenon may be caused by red cell aggregation occurring in those conditions.
