Left main coronary artery 'embolectomy' using a novel, straightforward technique

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Cardiothoracic Medicine

Background:

• Coronary artery bypass grafting (CABG) is a common procedure for coronary artery disease.
• Postoperative hemodynamic instability can occur following CABG, necessitating prompt diagnosis and management.
• Left main coronary artery embolism is a rare but potentially catastrophic complication after cardiac surgery.

Observation:

• A 60-year-old male patient developed severe hemodynamic decompensation three days after CABG.
• Clinical presentation suggested a critical obstruction in the left main coronary artery.
• A saddle embolus was identified in the left main coronary artery.

Findings:

• Aspiration thrombectomy was performed to remove the left main coronary artery saddle embolus.
• The patient experienced immediate and significant hemodynamic improvement post-thrombectomy.
• No further interventions such as angioplasty or repeat CABG were required.

Implications:

• Coronary thromboembolism must be considered in the differential diagnosis of hemodynamic collapse after CABG.
• Early diagnosis via coronary angiography and prompt aspiration thrombectomy can be life-saving.
• This case highlights the efficacy of aspiration thrombectomy in managing acute coronary artery emboli post-CABG.
