Treatment of Left Ventricular Aneurysm Without Symptoms
Asymptomatic left ventricular aneurysm represents a distinct clinical situation in which the decision to intervene must be carefully weighed against the expected natural course of the condition.
Clinical scenario
This protocol applies to patients with left ventricular aneurysm who do not have symptoms. Small, medium, and large left ventricular aneurysms without symptoms can be safely monitored, with an expected five-year survival of up to 90%.
Treatment approach
Management in this setting centres on medical therapy — including optimization of underlying cardiovascular risk factors and afterload reduction — along with a structured anticoagulation strategy whose scope depends on specific patient characteristics.
The complete regimen, decision criteria, and sequencing are available in the full protocol below.

- The management can include optimization of coronary artery disease risk factors for ischemia prevention, afterload reduction with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and anticoagulation to prevent thromboembolism.
- In terms of anticoagulation, the risk of LV mural thrombus is highest within the first month after acute infarction; therefore, it is always prudent to employ anticoagulation in all patients using warfarin the first three months after LV infarction.
- Long-term anticoagulation should be reserved for patients with large, friable thrombi protruding into the ventricular cavity, documented systemic embolization beyond the three months, or while receiving anticoagulants, and globally impaired LV function.
