Insights
Coronary artery aneurysms are dilations of heart arteries, often found incidentally. This review covers their causes, natural history, and treatments, highlighting key unanswered questions.
Area of Science:
- Cardiology
- Vascular Medicine
Background:
- Coronary artery aneurysms (CAAs) are abnormal dilations of coronary arteries.
- They are often incidentally discovered during coronary angiography.
- Epidemiology and natural history have been described in clinical series.
Purpose of the Study:
- To review the current knowledge on coronary artery aneurysms.
- To highlight unresolved questions regarding CAAs.
Main Methods:
- Literature review of clinical series and studies on coronary artery aneurysms.
- Synthesis of information on epidemiology, etiology, natural history, and treatment.
Main Results:
- Atherosclerotic coronary artery disease is the most common cause of CAAs.
- Other causes include congenital factors, inflammatory disorders, and connective tissue diseases.
- Kawasaki disease has a known association with CAAs.
Conclusions:
- Treatment options for CAAs include surgical, percutaneous, and medical interventions.
- Further research is needed to address important unresolved questions regarding CAAs.
Abstract:
Coronary artery aneurysms or ectasias are dilatations of arterial segments, which are typically incidentally identified at angiography. Several large clinical series have described the epidemiology and natural history of these malformations. The most common etiologic factor for coronary aneurysms is atherosclerotic coronary artery disease, but they can also be congenital or secondary to inflammatory or connective tissue disorders, with a well-known association with Kawasaki disease. Treatment may consist of surgical, percutaneous, or medical interventions. This review summarizes the current state of knowledge on coronary artery aneurysms and highlights important unresolved questions.
