Left main coronary artery dissection during percutaneous coronary intervention in patient with chronic total...

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Coronary angiography and angioplasty are standard procedures for diagnosing and treating coronary artery disease.
• Left main coronary artery dissection is a rare but severe complication associated with these interventions.

Observation:

• The case involved a patient undergoing intervention for a chronic total occlusion (CTO).
• A dissection of the left main coronary artery was induced by a guide catheter during the procedure.

Findings:

• The dissection occurred specifically during the management of CTO and subsequent bailout stenting of the left main and Left Anterior Descending (LAD) artery.
• This event underscores the risks associated with complex coronary interventions.

Implications:

• Careful guide catheter manipulation is crucial to prevent catastrophic complications like left main dissection.
• Prompt recognition and management are vital for improving outcomes in such critical situations.
• This case contributes to the understanding of rare complications in interventional cardiology.
