2025年1月31日 · Echocardiography, cardiac MRI, and cardiac ventriculography form the mainstay of imaging. A key consideration is whether an aneurysm represents a true or false aneurysm due to the differing prognoses and management. True aneurysms typically have a wide neck. The CXR findings of a left ventricular aneurysm are typical and include:

2023年4月3日 · Most of the LV aneurysms are asymptomatic and are found in follow-up echocardiography. However, large symptomatic LV aneurysms can cause heart failure, ventricular tachyarrhythmias, and sudden cardiac death.

Left ventricular aneurysm is the discrete thinning of the ventricular wall (<5 mm) with akinetic or dyskinetic wall motion causing an out-pouching of the ventricle. Given the propensity for pseudoaneurysms to rupture leading to cardiac tamponade, shock, and death, compared with a more benign natural history for true aneurysms, accurate ...

2022年2月11日 · The authors found that 3D echocardiography was feasible and reproducible for the evaluation of LV size, shape, and function for patients with LV aneurysm. 3D echocardiography provided highly accurate quantification of LV size, shape, global systolic function, regional wall-motion, and myocardial scar, in a direct comparison with CMR.

Left ventricular aneurysm most commonly results from acute myocardial infarction (MI). Other causes of LVA include Chagas’ disease, cardiac sarcoidosis, and presence of Lewitic gummas in the myocardium. Midventricular hypertrophy and obstruction have been associated with apical infarction and LVA .

An echocardiography is the preferred modality for diagnosing LV aneurysm. It is helpful for estimating the size and location of the aneurysm, as well as the presence of thrombosis in the wall of the aneurysm.

2024年10月8日 · In patients presenting with chest pain and ST elevation on the ECG it is vital to be able to be able to distinguish between LV aneurysm (“old MI”) and acute STEMI. The ratio of T-wave to QRS complex amplitude has been validated as a means of differentiating between LV aneurysm and acute STEMI:

2018年2月19日 · Myocardial infarction is usually transmural to cause an LV aneurysm; 50% occur within 48 hours from the onset of pain, the remainder within 2 weeks; Angiographically defined LV aneurysms has been reported in 7.6% of patients with coronary artery disease referred for coronary angiogram > 80% of LV aneurysm involve the anterior wall +/- apex

2014年1月10日 · Transthoracic echocardiography plays an important role and provides assessment of LV structure and function, however, inferior wall aneurysm can be difficult to visualize particularly in patients with sub-optimal image quality.

The left ventricular (LV) ejection fraction was 30% and an apical aneurysm could be clearly identified. The preoperative transthoracic echocardiogram without and with intravenous contrast confirmed a 3.5x 1.5 cm left ventricular aneurysm.
