Atrial fibrillation offers more than one path — a surgical Maze, a catheter ablation, a Watchman for stroke prevention, or simply controlling the rate. Which is right for you? Do you need a procedure now? An independent review by a cardiac surgeon and a cardiologist, with triple risk-model scoring (STS, EuroSCORE II, AATS), answers these questions with your real numbers. A written review is delivered within 24 hours of your records — from $500.

An AFib second opinion exists to answer four questions clearly and honestly. We address each one directly, in writing, signed by your Heart Team.
A surgical Maze procedure and a catheter ablation both aim to restore normal rhythm, but they differ profoundly in approach, invasiveness, and durability. We review whether your atrial fibrillation pattern, your prior treatments, and any planned heart surgery point toward one approach over the other.
Not every patient with AFib needs a procedure at all. For some, controlling the heart rate and managing stroke risk is the right strategy; for others, restoring sinus rhythm offers real benefit. We confirm whether you are on the appropriate side of that decision before any intervention is recommended.
AFib treatment is rarely a single forced choice. We confirm whether an ablation, a surgical Maze, or a Watchman device is genuinely indicated for you now, or whether optimized medical therapy and watchful management is the better next step at this stage.
Stroke prevention is central to AFib care. We review your stroke and bleeding risk, whether anticoagulation is appropriate, and whether left atrial appendage closure with a Watchman or surgical clip is a reasonable alternative if blood thinners are not tolerable for you.
Understanding what each AFib option actually does — and the rate-versus-rhythm strategy behind it — is the foundation of an informed decision. Here is what an independent Heart Team review examines.
The Cox-Maze procedure creates a precise pattern of scar lines in the atria to block the abnormal electrical circuits that drive atrial fibrillation. Performed surgically (often with cryo or radiofrequency energy), it is the most durable rhythm-restoring option, with high long-term freedom from AFib. It is most often considered for persistent or long-standing AFib, or when a patient is already undergoing heart surgery for another reason.
Catheter ablation treats AFib through catheters threaded to the heart from the groin, isolating the pulmonary veins and other triggers without opening the chest. It offers a less invasive path with shorter recovery and is often first-line for paroxysmal AFib. Durability varies, and some patients need a repeat procedure. Whether ablation or a surgical approach is right depends on your AFib pattern, atrial size, and prior treatments.
Most stroke-causing clots in AFib form in the left atrial appendage. A Watchman device, implanted via catheter, or a surgical clip applied during heart surgery, closes off that pouch to reduce stroke risk in patients who cannot safely take long-term anticoagulation. It addresses stroke prevention, not the rhythm itself, and is a distinct decision from Maze or ablation.
A foundational AFib decision is whether to control the rate (let AFib continue but keep the heart rate in check and manage stroke risk) or pursue rhythm control (restore and maintain normal sinus rhythm with medication, ablation, or surgery). The right strategy depends on your symptoms, heart function, age, and AFib duration. Choosing the wrong one exposes you to risk without benefit.
When AFib surgery is on the table, we calculate your operative and post-operative risk using validated cardiac surgery models — STS, EuroSCORE II, and AATS — together with a frailty assessment, so you have a concrete, personalized estimate of risk rather than a vague reassurance. Knowing your real numbers is essential to weighing a surgical Maze against catheter or medical options.
A surgical approach to AFib is most compelling when you are already having heart surgery, or when less invasive options have been exhausted. Here is what an independent review weighs.
If you are already scheduled for valve surgery, coronary bypass, or another open-heart operation and you have a history of atrial fibrillation, a concomitant Maze procedure can often be added at the same time to treat the AFib. This avoids a separate intervention and can meaningfully improve long-term rhythm outcomes. We review whether a concomitant Maze should be part of your planned operation.
During the same operation, the left atrial appendage can be surgically closed or excised to reduce future stroke risk. We assess whether appendage management should accompany your planned heart surgery, particularly if you have AFib and elevated stroke risk.
A standalone surgical Maze (without other heart surgery) is generally reserved for symptomatic patients with persistent or long-standing AFib who have failed catheter ablation or are not good ablation candidates. We confirm whether your situation genuinely meets that threshold, or whether a less invasive path remains appropriate first.
Your cardiac surgeon and cardiologist lead the review to evaluate every AFib option for your specific situation.
We map your AFib pattern, symptoms, and prior treatments against current ACC/AHA/HRS guidelines to confirm whether rate control, rhythm control, catheter ablation, a surgical Maze, or a Watchman is genuinely the right next step for you.
Systematic comparison of catheter ablation, surgical Maze (standalone or concomitant), and left atrial appendage closure for your specific atrial anatomy, AFib duration, and treatment history.
When surgery is considered, STS, EuroSCORE II, and AATS risk models calculated from your clinical data, with predicted operative mortality and major morbidity plus a frailty assessment that generic risk quotes often omit.
Independent review of your stroke and bleeding risk and your anticoagulation plan, including whether left atrial appendage closure is a reasonable alternative if long-term blood thinners are not tolerable.
Independent appraisal of your ECGs and rhythm monitoring, echocardiogram, any prior ablation or operative reports, and the proposed plan, checking that the recommendation matches what your data actually show.
Begin wherever you feel most comfortable. Every path reaches the same Heart Team.
A catheter ablation treats atrial fibrillation through thin catheters threaded to the heart from the groin, isolating the pulmonary veins and other triggers without opening the chest. It is less invasive, has a shorter recovery, and is often first-line for paroxysmal AFib. A surgical Maze (Cox-Maze) creates a precise pattern of scar lines in the atria during heart surgery to block the circuits that drive AFib, and it is the most durable rhythm-restoring option, particularly for persistent or long-standing AFib or when a patient is already having other heart surgery. Which is right depends on your AFib pattern, atrial size, and prior treatments, and a second opinion helps clarify that choice.
The Watchman is a small device implanted via catheter to close off the left atrial appendage, where most stroke-causing clots in atrial fibrillation form. It is intended for patients with AFib who are at elevated stroke risk but cannot safely take long-term anticoagulation (blood thinners). Importantly, the Watchman addresses stroke prevention, not the abnormal rhythm itself, so it is a separate decision from a Maze procedure or a catheter ablation. During open-heart surgery, the appendage can instead be closed with a surgical clip. Our review weighs whether appendage closure is appropriate for you.
This is one of the most important AFib decisions. Rate control means allowing the atrial fibrillation to continue while keeping the heart rate in a safe range and managing stroke risk, which suits many patients with minimal symptoms. Rhythm control means restoring and maintaining normal sinus rhythm through medication, catheter ablation, or surgery, which can benefit patients with significant symptoms, heart failure, or recent-onset AFib. The right strategy depends on your symptoms, heart function, age, and how long you have been in AFib. An independent review confirms which side of that decision is right for you before any procedure is recommended.
Yes, and it often should be considered. If you have a history of atrial fibrillation and are already scheduled for valve surgery, coronary bypass, or another open-heart operation, a concomitant Maze procedure can frequently be added at the same time to treat the AFib without a separate intervention. The same operation can also include surgical closure of the left atrial appendage to reduce stroke risk. A second opinion confirms whether a concomitant Maze and appendage management should be part of your planned surgery.
In almost all cases, no. Your White Glove Insights™ Report is delivered within 24 hours of receiving your complete medical records, so a second opinion typically fits well inside the planning window for an elective ablation or AFib surgery. If your situation is urgent, contact our team to discuss an expedited turnaround, and we would never advise delaying genuinely time-critical care.
