Insights
Spontaneous left main coronary artery dissection is rare. This case highlights successful surgical management in a diabetic patient with an uneventful recovery, emphasizing prompt intervention for this critical condition.
Area of Science:
- Cardiology
- Vascular Surgery
- Medical Case Reports
Background:
- Spontaneous coronary artery dissection (SCAD) is a rare but serious condition.
- Left main coronary artery dissection is particularly uncommon and carries significant risks.
- Diabetic patients may present unique challenges in cardiovascular disease management.
Observation:
- A 58-year-old diabetic male presented with primary spontaneous left main coronary artery dissection.
- The dissection was identified during coronary angiography.
- Despite the persistent lesion, the patient remained asymptomatic during the procedure.
Findings:
- Urgent coronary artery bypass grafting (CABG) was successfully performed.
- The surgical procedure was uneventful.
- The patient experienced no peri-procedural chest discomfort or electrocardiographic changes.
Implications:
- This case demonstrates the feasibility and effectiveness of surgical revascularization for spontaneous left main coronary artery dissection.
- Prompt surgical intervention can lead to favorable outcomes even in complex cases.
- Highlights the importance of considering SCAD in the differential diagnosis of acute coronary syndromes, even in diabetic patients.
Abstract:
Coronary artery dissection is a devastating disease, but spontaneous left main coronary artery dissection is extremely rare. We present the case of a 58-year-old diabetic man who was found to have primary spontaneous left main coronary artery dissection during a coronary angiography examination. Although the dissecting lesion persisted, he had no peri-procedural chest discomfort or electrocardiographic change. We performed urgent coronary artery bypass grafting, which was uneventful. The patient received regular cardiovascular follow-up and did not complain of any postoperative chest discomfort. He had an uneventful recovery.
