Abstract:
We report the case of a 67 year-old patient who presented with worsening chest pain and shortness of breath, four days post acute myocardial infarction. Contrast enhanced computed tomography of the chest ruled out a pulmonary embolus but revealed an unexpected small subepicardial aneurysm (SEA) in the lateral left ventricular wall which was confirmed on cardiac magnetic resonance imaging. Intraoperative palpation of the left lateral wall was guided by the cardiac MRI and CT findings and confirmed the presence of focally thinned and weakened myocardium, covered by epicardial fat. An aneurysmorrhaphy was subsequently performed in addition to coronary bypass surgery and a mitral valve repair. The patient was discharged home on post operative day eight in good condition and is feeling well 2 years after surgery.
Insights
A rare subepicardial aneurysm (SEA) was unexpectedly found in a patient experiencing chest pain after myocardial infarction. Surgical repair of the left ventricular aneurysm was successful, with the patient recovering well.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Medical Imaging
Background:
- Acute myocardial infarction can lead to various cardiac complications.
- Subepicardial aneurysms (SEAs) are rare cardiac abnormalities.
- Early diagnosis and intervention are crucial for managing post-MI complications.
Observation:
- A 67-year-old patient presented with worsening chest pain and dyspnea four days post-myocardial infarction.
- Computed tomography (CT) and cardiac magnetic resonance imaging (MRI) revealed a small subepicardial aneurysm in the left ventricular lateral wall.
- Intraoperative findings confirmed focally thinned and weakened myocardium consistent with an aneurysm.
Findings:
- The subepicardial aneurysm was successfully identified using advanced imaging modalities (CT and MRI).
- The patient underwent successful aneurysmorrhaphy, coronary artery bypass grafting, and mitral valve repair.
- The patient experienced a good recovery and remained well two years post-surgery.
Implications:
- This case highlights the importance of considering rare complications like SEAs in patients with persistent symptoms post-myocardial infarction.
- Multimodality imaging plays a vital role in diagnosing and guiding the surgical management of such conditions.
- Timely surgical intervention for subepicardial aneurysms can lead to favorable long-term outcomes.
