An LV pseudoaneurysm is a contained rupture of the left ventricular wall, typically a serious complication following myocardial infarction, cardiac surgery, or trauma. Unlike a true aneurysm, it lacks endocardial and myocardial layers, instead being walled off by thrombus and pericardium. This critical distinction is vital in cardiac ultrasound for accurate diagnosis, as rupture risk is high due to its fragile wall.
Echocardiography plays a crucial role in identifying LV pseudoaneurysms. Ultrasound reveals a narrow neck connecting the pseudoaneurysm to the left ventricle, differentiating it from a broad-based true aneurysm. Early detection via medical ultrasound is essential for patient management and intervention, highlighting the importance of skilled cardiac imaging in preventing life-threatening complications.
