Summary
Left ventricular mural thrombus, a complication of myocardial infarction, is common in large anterior Q-wave infarctions, especially with aneurysms. Imaging and anticoagulation are key for management.
Area of Science:
- Cardiology
- Cardiovascular Medicine
- Thrombosis Research
Background:
- Left ventricular mural thrombus is a known complication following acute myocardial infarction.
- The occurrence of mural thrombus is linked to infarction characteristics like location and size, particularly in anterior Q-wave infarctions and left ventricular aneurysms.
Purpose of the Study:
- To summarize the occurrence, identification, and management of left ventricular mural thrombus post-myocardial infarction.
Main Methods:
- Review of existing literature on left ventricular mural thrombus.
- Discussion of diagnostic modalities including echocardiography, indium-111 labeled platelet scintigraphy, computed tomography, and magnetic resonance imaging.
- Overview of therapeutic strategies, focusing on anticoagulation.
Main Results:
- Left ventricular mural thrombus incidence is higher with extensive anterior myocardial infarction and left ventricular aneurysm.
- Various imaging techniques can effectively detect left ventricular mural thrombus.
- Anticoagulation therapy (heparin and warfarin) is the standard treatment to prevent thrombus propagation and embolization.
Conclusions:
- Left ventricular mural thrombus is a significant complication of myocardial infarction, particularly in specific patient subgroups.
- Accurate diagnosis relies on advanced imaging modalities.
- Anticoagulation plays a crucial role in managing this condition and preventing embolic events.
