Multivessel coronary angioplasty with anomalous origin of the left main coronary artery

Area of Science:

• Cardiology
• Interventional Cardiology
• Congenital Heart Disease

Background:

• Anomalous origin of the left main coronary artery from the right aortic sinus is a rare congenital heart defect.
• This anomaly can lead to significant coronary artery stenosis and adverse cardiovascular events.
• Percutaneous coronary intervention in such complex anatomies presents unique challenges.

Observation:

• A patient presented with an anomalous left main coronary artery originating from the right aortic sinus of Valsalva.
• The patient had severe and distal stenoses in the left anterior descending, circumflex, and right coronary arteries.
• Coronary angioplasty was performed using specific angioplasty hardware to address these stenoses.

Findings:

• The coronary angioplasty procedure successfully treated multiple severe and distal stenoses in the anomalous coronary system.
• Angiographic follow-up exceeding 2 years demonstrated no evidence of restenosis.
• The patient remained clinically well, indicating the long-term efficacy of the intervention.

Implications:

• This case highlights the feasibility and long-term success of percutaneous coronary intervention for complex coronary stenoses in anomalous left main coronary artery.
• The choice of appropriate angioplasty hardware is crucial for navigating and treating stenoses in these challenging anatomical variations.
• This report adds valuable data to the limited literature on interventional management of this rare coronary anomaly.
