Abnormal left cardiac border due to an atherosclerotic coronary artery aneurysm
Insights
This case study highlights an uncommon left anterior descending coronary artery aneurysm, a rare cause of an abnormal cardiac silhouette. Early detection via coronary angiography is crucial for appropriate management to prevent fatal myocardial infarction.
Area of Science:
- Cardiology
- Radiology
- Vascular Surgery
Background:
- Coronary artery aneurysms are rare vascular abnormalities.
- An abnormal left cardiac border on chest roentgenograms can indicate various pathologies.
- Left anterior descending coronary artery aneurysms are particularly uncommon.
Abstract:
A 57-year-old man had an aneurysm of the left anterior descending coronary artery that appeared as a bulge of the left cardiac border on plain chest roentgenograms. The aneurysm enlarged over a four-year period, and death resulted from myocardial infarction. The importance of recognizing this uncommon cause of an abnormal left cardiac border is stressed because further investigation by coronary angiography should be done before resection or bypass of the aneurysm.
