Left main coronary artery aneurysm

Area of Science:

• Cardiology
• Vascular Medicine
• Medical Imaging

Background:

• Left main coronary artery aneurysms (LMCA) are uncommon vascular abnormalities.
• While often asymptomatic, LMCA can lead to severe complications like myocardial infarction and sudden death.
• Atherosclerosis is the primary cause, but autoimmune diseases and congenital factors are also implicated.

Observation:

• A case report of a 63-year-old male patient presenting with a giant LMCA.
• The patient was asymptomatic at the time of diagnosis.
• Coronary angiography revealed severely ectatic coronary arteries alongside the giant LMCA.

Findings:

• The study presents a rare instance of a giant LMCA in an asymptomatic patient.
• The co-occurrence of severely ectatic coronary arteries with the giant LMCA is noted.
• This case underscores the varied presentations of coronary artery aneurysms.

Implications:

• Highlights the importance of recognizing rare coronary artery pathologies.
• Suggests the need for vigilance in evaluating ectatic coronary arteries, even in asymptomatic individuals.
• Contributes to the understanding of LMCA etiology and management strategies.
