Summary
Sudden hemodynamic collapse after coronary artery bypass grafting (CABG) can be caused by a left main coronary artery saddle embolus. Urgent aspiration thrombectomy can rapidly resolve this critical complication.
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.
