Insights
A rare, large left main coronary artery aneurysm was diagnosed in a male patient presenting with exertional angina. Medical therapy was planned due to the rarity and lack of standard treatment for coronary artery aneurysms.
Area of Science:
- Cardiology
- Vascular Medicine
- Diagnostic Imaging
Background:
- Coronary artery aneurysms are uncommon, with prevalence varying from 0.2% to 6% in reported series.
- These aneurysms can lead to significant cardiac symptoms, including exertional angina.
Observation:
- A male patient presented with a massive aneurysm of the left main coronary artery.
- The entire left coronary system originated from this large aneurysm.
Findings:
- Coronary angiography confirmed the aneurysm, with subsequent multislice computed tomography and 3D reconstruction providing detailed anatomical information.
- The patient experienced exertional angina attributed to the coronary artery aneurysm.
Implications:
- The management of such rare and large coronary artery aneurysms lacks standardized protocols.
- Medical therapy was chosen after multidisciplinary consultation, highlighting the need for individualized treatment approaches.
- This case underscores the importance of advanced imaging in diagnosing and characterizing complex coronary artery abnormalities.
Abstract:
Coronary artery aneurysms are rare findings in patients referred for coronary angiography. Their prevalence ranges between 0.2% and 6% in different case series. We describe a male patient with a huge left main coronary artery aneurysm causing exertional angina, which was diagnosed with coronary angiography. All of the left coronary system arose from the aneurysm. He underwent coronary angiography again, followed by multislice computed tomography with a three-dimensional reconstruction. Although there is no known standard treatment modality for such aneurysms, we planned medical therapy after consultation with the cardiovascular surgery department. The patient's first visit was in March 2013, and he was thereafter followed up until September 2016.
