Summary
Simultaneous cryoablation for atrial fibrillation and coronary artery bypass grafting was successful. Intraoperative mapping guided epicardial ablation of the left atrial appendage, treating chronic atrial fibrillation effectively.
Area of Science:
- Cardiovascular Surgery
- Cardiac Electrophysiology
Background:
- Chronic atrial fibrillation often requires surgical intervention.
- Coronary artery bypass grafting is a standard procedure for coronary artery disease.
Observation:
- A 55-year-old male patient underwent simultaneous coronary artery bypass grafting and atrial fibrillation ablation.
- Computerized atrial mapping identified the left atrial appendage as the source of irregular electrical discharges.
Findings:
- Epicardial cryoablation of the left atrial appendage successfully treated atrial fibrillation without opening the left atrium.
- The procedure was performed concurrently with coronary artery bypass grafting.
Implications:
- Intraoperative mapping enhances the precision and success of atrial fibrillation ablation.
- Minimally invasive, map-guided cryoablation offers a viable option for combined cardiac procedures.
