Serial Changes of Aortic Vulnerable Plaques Observed via Non-Obstructive General Angioscopy

Area of Science:

• Cardiovascular Medicine
• Medical Imaging
• Atherosclerosis Research

Background:

• Aortic vulnerable plaques pose a significant risk, but their stabilization mechanisms remain unclear.
• Non-obstructive general angioscopy (NOGA) offers detailed visualization of aortic intimal atherosclerosis.
• Understanding plaque behavior is crucial for managing cardiovascular disease.

Observation:

• A 57-year-old male with acute myocardial infarction underwent percutaneous coronary intervention (PCI).
• NOGA identified vulnerable puff-chandelier plaques in the aortic arch during evaluation for atherosclerosis.
• The patient received intensive low-density lipoprotein cholesterol-lowering therapy with a potent statin.

Findings:

• After 8 months of lipid-lowering therapy, follow-up NOGA demonstrated stabilization of previously identified aortic plaques.
• The observed plaque stabilization occurred in the same aortic arch lesions.
• This suggests a direct correlation between lipid-lowering treatment and plaque regression.

Implications:

• NOGA emerges as a valuable tool for assessing the efficacy of lipid-lowering therapies in stabilizing aortic plaques.
• The findings contribute to a better understanding of aortic atherosclerosis management.
• This approach may guide future treatment strategies for patients at risk of cardiovascular events.
