Atrial Fibrillation Surgery: How Long Does It Take?

Atrial fibrillation (AFib) surgery typically takes around 2 hours to complete. However, the exact duration can vary depending on several factors, including the surgeon's expertise, the complexity of the patient's condition, and any challenges encountered during vascular access or catheter placement. In some cases, the procedure may be completed in as little as 1.5 hours, while more complex cases could extend to 3 hours or more.

Key Factors Influencing Procedure Time

Surgical Skill and Experience: Experienced electrophysiologists may perform the procedure more efficiently, potentially reducing the overall time spent in the operating room.

Patient-Specific Conditions: The presence of anatomical abnormalities, prior heart surgeries, or complications during vascular access can prolong the procedure. Additionally, the type of AFib—whether paroxysmal, persistent, or long-standing persistent—can also impact the duration.

Why Surgery Time Isn't the Most Important Consideration

While the length of the procedure is a practical detail, it should not be the primary factor in deciding whether to undergo treatment. For patients who are candidates for radiofrequency ablation, this procedure offers a significant advantage over medication. Unlike drug therapy, which may only manage symptoms, ablation aims to restore and maintain normal sinus rhythm, addressing the root cause of AFib.

Benefits of Radiofrequency Ablation

Left untreated, AFib significantly increases the risk of stroke—sometimes by fivefold compared to individuals with normal heart rhythm. Radiofrequency ablation is currently the most effective intervention for restoring normal heart rhythm and reducing this risk. While success rates vary, approximately 60% to 70% of patients experience long-term relief from AFib symptoms after the procedure.

Understanding the Success Rate

It's important to note that while ablation is highly beneficial, it is not 100% guaranteed. Some patients may experience a recurrence of AFib, and in certain cases, a second procedure may be necessary. However, for many, the procedure offers a meaningful improvement in quality of life and a reduced need for long-term medication.
