Summary
Blunt chest injury can cause left ventricular aneurysms. A rare case of pseudoaneurysm from myocardial dissection was successfully treated with surgical exclusion.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Trauma Surgery
Background:
- Left ventricular aneurysms are a known complication of blunt chest trauma.
- Previous cases attribute this to myocardial contusion or vascular lesions causing necrosis.
- A pseudoaneurysm represents a distinct pathological entity.
Observation:
- We present a unique case of a left ventricular pseudoaneurysm.
- This pseudoaneurysm originated from a myocardial dissection initiated by a small endocardial tear.
- The injury mechanism differed from typical myocardial contusion.
Findings:
- The patient developed a pseudoaneurysm following blunt chest injury.
- The pseudoaneurysm resulted from a dissection of the myocardium.
- Surgical intervention successfully excluded the pseudoaneurysm.
Implications:
- This case expands the understanding of left ventricular aneurysm formation after trauma.
- It highlights myocardial dissection as a potential cause.
- Endoaneurysmal patch closure is a viable surgical option for these rare injuries.
