[Coronary artery ectasia. Apropos of a case treated surgically in 2 stages]
Insights
This case study highlights coronary artery aneurysms, a rare condition. Long-term anticoagulant therapy is crucial for patients with coronary aneurysms and atheroma to prevent myocardial infarction.
Area of Science:
- Cardiology
- Vascular Medicine
- Interventional Cardiology
Background:
- Coronary artery aneurysms (CAAs) are uncommon vascular abnormalities.
- Atherosclerosis is a known risk factor and underlying cause for CAAs.
- Myocardial infarction (MI) can occur secondary to CAAs.
Observation:
- A 35-year-old male presented with MI and localized aneurysms of the left anterior descending and left circumflex arteries, and diffuse dilatation of the right coronary artery.
- Severe stenosis was noted on the right coronary artery, indicating an atheromatous cause.
- A second MI occurred due to intra-aneurysmal thrombosis after withdrawal of anticoagulant therapy.
Findings:
- Surgical intervention, including coronary artery bypass grafting (CABG) and aneurysm exclusion, was performed.
- The patient demonstrated good long-term outcomes following surgical management.
- Progression of aneurysmal and atheromatous disease was observed over time.
Implications:
- This case underscores the importance of lifelong anticoagulant therapy in managing patients with CAAs and concurrent atherosclerosis.
- Aggressive medical and surgical management can lead to favorable postoperative prognoses.
- Further research into the long-term management and outcomes of CAA is warranted.
Abstract:
The authors report a new case of coronary artery aneurysms in a 35 year old man who presented with a rudimentary myocardial infarct. Coronary angiography showed a localized aneurysm of the left anterior descending and left circumflex arteries, and a diffuse dilatation of the right coronary artery. The underlying cause was certainly atheroma because a severe stenosis was observed on the right coronary artery in association with the aneurysm. Five years later aorto-right coronary bypass surgery, when anticoagulant therapy was withdrawn, a second rudimentary infarct occurred due to intra aneurysmal thrombosis on the left circumflex artery. The aneurysmal and atheromatous disease had progressed, justifying a double bypass on the left anterior descending and circumflex arteries with exclusion of the two aneurysms. The patient was reviewed 14 months and 8 years after the first attack of spontaneous angina with good results. This and other reported cases underline the good postoperative prognosis and the necessity for a life-long anticoagulant therapy.
