Key result
MI with normal coronaries can lead to mechanical complications like LV aneurysm and moderate-to-severe MR.
Why the study?
Mechanical complications such as posterobasal left ventricular aneurysm with moderate to severe mitral regurgitation can occur after myocardial infarction with normal coronary arteries despite generally favorable prognosis.
Case Report (n=1)
Mechanical complications such as posterobasal left ventricular aneurysm with moderate to severe mitral regurgitation can occur in patients with myocardial infarction with normal coronary arteries, despite the generally favorable prognosis.
We present a case of a 64-year-old woman with signs of debilitating condition including anginal chest pain, exertional dyspnea, and depression. The patient had previously suffered from a myocardial infarction after a loss of a close family member. Workup showed a posterobasal left ventricular aneurysm and moderate to severe mitral regurgitation in the absence of coronary atherosclerosis. Routine ultrasonography revealed abdominal aortic aneurysm and intraabdominal aortic deviation. The patient was immediately started on optimal medical treatment. On repeat assessment general condition was satisfactory, vital signs were normal, and investigations showed no signs of progressive heart failure or other significant clinical changes. Although prognosis in patients with myocardial infarction with normal coronary arteries is generally considered favorable, mechanical complications such as posterobasal left ventricular aneurysm with moderate to severe mitral regurgitation are possible.

Kalinin et al. (2018) conducted a case report in Posterobasal left ventricular aneurysm after myocardial infarction with normal coronary arteries (n=1). Optimal medical treatment was evaluated on Clinical status on repeat assessment. Myocardial infarction with normal coronary arteries can lead to mechanical complications such as posterobasal left ventricular aneurysm with moderate to severe mitral regurgitation.
