Insights
A dissecting aneurysm of the left main coronary artery in a patient with myocardial infarction showed signs of spontaneous healing. This rare finding was observed during histological examination after the patient
Area of Science:
- Cardiology
- Vascular Surgery
- Pathology
Background:
- Acute anterior myocardial infarction can present with complex coronary artery pathologies.
- Dissecting aneurysms of the left main coronary artery are rare and carry a high risk of mortality.
- Spontaneous healing of such vascular lesions is not well-documented.
Abstract:
A 37-year-old woman was admitted with an acute anterior myocardial infarction. Coronary arteriography revealed a dissecting aneurysm of the left main coronary artery. The patient died from perioperative myocardial infarction following aortocoronary bypass surgery on the 102nd hospital day. Histologic sections of the aneurysm revealed that granulation tissue had replaced the aneurysm, suggesting spontaneous healing of the dissecting aneurysm.
