Overview
Acquired aneurysm of the left ventricular (LV) wall results from myocardial infarction or other insults leading to localized dilation and thinning of the ventricular wall, potentially complicating cardiac function and increasing the risk of rupture or thromboembolism 1.Diagnosis
Imaging Techniques: Utilize cardiac CT and MRI for detailed anatomical assessment 1.
3D Modeling: Consider 3D rapid prototyping models for precise surgical planning, aiding in identification of risk structures and optimal resection lines 1.Management
Surgical Resection: Primary treatment involves surgical resection of the aneurysm with ventricular remodeling to restore adequate ventricular function 1.
Preoperative Planning: Employ 3D-printed models to facilitate surgical planning, ensuring sufficient LV volume post-remodeling 1.Special Populations
No Specific Guidance: The provided abstracts do not offer specific recommendations for pregnancy, pediatrics, elderly patients, or those with comorbidities 1.Key Recommendations
Utilize 3D rapid prototyping models for preoperative planning in LV aneurysm resection to improve surgical outcomes (Evidence: Moderate) 1.
Perform surgical resection with ventricular remodeling to address LV aneurysm, aiming to restore normal ventricular function (Evidence: Expert opinion) 1.
Consider advanced imaging techniques (CT, MRI) for comprehensive anatomical assessment prior to surgical intervention (Evidence: Moderate) 1.References
