Abstract:
A pseudoaneurysm refers to a contained rupture of the myocardium with a tenuous pericardium walling off the leak. It needs to be differentiated from a true aneurysm by the fact that there is lack of myocardial tissue in the wall of a pseudoaneurysm. The differentiation between the two is pertinent as true aneurysms can be treated medically while pseudoaneurysms require urgent surgical treatment. Untreated pseudoaneurysms carry a high risk of rupture and mortality. We report a case of cardiac pseudoaneurysm developing in a 46-year-old male who had suffered myocardial infarction four months back. The patient now presented with chest pain and dyspnoea. CECT chest revealed a partially thrombosed large pseudoaneurysm arising from the posterior wall of left ventricle. While the clinical diagnosis of this entity is difficult, CECT plays a pivotal role in the non-invasive detection of pseudoaneurysms.
Insights
Cardiac pseudoaneurysms, a contained myocardial rupture, require urgent surgery and differ from true aneurysms. Early detection via CECT imaging is crucial for patient survival.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Pseudoaneurysms are contained myocardial ruptures lacking myocardial tissue in their walls, distinct from true aneurysms.
- Differentiating pseudoaneurysms from true aneurysms is critical due to differing treatment modalities and prognoses.
Observation:
- A 46-year-old male presented with chest pain and dyspnea four months post-myocardial infarction.
- Computed tomography angiography (CECT) revealed a large, partially thrombosed pseudoaneurysm originating from the left ventricle's posterior wall.
Findings:
- Clinical diagnosis of cardiac pseudoaneurysms can be challenging.
- CECT imaging plays a pivotal role in the non-invasive detection and characterization of pseudoaneurysms.
Implications:
- Pseudoaneurysms necessitate urgent surgical intervention to prevent rupture and mortality.
- Accurate diagnosis through advanced imaging like CECT is vital for timely and appropriate patient management.
