Posterobasal left ventricular aneurysm after myocardial infarction with normal coronary arteries: Case-report

Area of Science:

• Cardiology
• Vascular Surgery

Background:

• Myocardial infarction (MI) in patients with normal coronary arteries typically has a favorable prognosis.
• However, mechanical complications can arise, necessitating thorough investigation.

Observation:

• A 64-year-old woman presented with anginal chest pain, exertional dyspnea, and depression post-MI.
• Workup revealed a posterobasal left ventricular aneurysm and moderate to severe mitral regurgitation without coronary atherosclerosis.
• Abdominal aortic aneurysm and intraabdominal aortic deviation were also noted on ultrasonography.

Findings:

• The patient was initiated on optimal medical management.
• Repeat assessments showed a satisfactory general condition and stable vital signs, with no signs of progressive heart failure.

Implications:

• This case underscores the possibility of significant mechanical complications, including left ventricular aneurysm and mitral regurgitation, even in MI with normal coronary arteries.
• Optimal medical treatment can stabilize patients with these complex cardiovascular conditions.
