Thoracoscopic Biatrial Ablation Using Bipolar Radiofrequency

A seventy-four-year-old male underwent a thoracoscopic biatrial ablation procedure with bipolar frequency. His past cardiac history was significant, with a three-year history of atrial fibrillation and multiple failed cardioversions.  

Further details of the procedure are as follows: 

Preoperative  

• TTE: EF 65%  
• Biatrial enlargement  
• Mild mitral valve regurgitation 

Cardiac Catheterization  

• No significant coronary artery disease 
• Right dominant 

Result  

Converted to normal sinus rhythm (NSR) postoperatively and remains in NSR three months post-op.
