Description

Catheter ablation is a therapeutic technique using a cryoballoon to eliminate conduction defects.

Maze or Modified Maze Procedures, also known as (a.k.a.) surgical ablation, are performed on a non-beating heart during the cardiopulmonary bypass to destroy the arrhythmic area of the heart.

Hybrid catheter and surgical ablation (HyCASA) is a minimally-invasive procedure for treatment of atrial fibrillation. The procedure combines thoroscopic epicardial ablation performed by a surgeon and percutaneous endocardial ablation performed by an electrophysiologist as directed by the electrophysiology study. It is performed either as part of a single 'joint' procedure or as two (2) separate ablation procedures.

Professional Statements and Societal Positions Guidelines

2023 ACC/AHA/ACCP/HRS Guideline for the Diagnosis and Management of Atrial Fibrillation - 2023

The guideline provides comprehensive recommendations on various ablation procedures for atrial fibrillation.

Catheter Ablation Procedures
- Catheter ablation, including both radiofrequency ablation and cryoablation, is recommended for rhythm control in individuals with symptomatic paroxysmal or persistent AF. This approach is particularly beneficial when antiarrhythmic drug therapy is ineffective, not tolerated, or preferred as a first-line therapy after considering individual preferences and clinical characteristics
Operative Ablation Procedures
- Surgical ablation procedures such as Maze and modified Maze procedures, are recommended for individuals with AF undergoing other cardiac surgeries (e.g., coronary artery bypass grafting or valve surgery). These procedures aim to maintain sinus rhythm and reduce AF-related symptoms.
Hybrid and Surgical Ablation (HyCASA)
- Hybrid approaches, combining surgical and catheter ablation techniques, may be considered for selected patients with persistent or long-standing persistent AF, especially when prior ablation attempts have failed. This strategy leverages the strengths of both methods to achieve better rhythm control

Society of Thoracic Surgeons (STS) 2023 Clinical Practice Guidelines for the Surgical Treatment of Atrial Fibrillation (AF) - 2023

The guideline provides updated recommendations to enhance patient outcomes.

Surgical Ablation
- Class I Recommendation: Surgical ablation is advised for all individuals with AF undergoing first-time, non-emergent cardiac surgery, including both mitral and non-mitral operations, to restore sinus rhythm and improve long-term outcomes
- Class IIa Recommendation: For symptomatic AF individuals without structural heart disease, who have not responded to class I/III antiarrhythmic drugs or catheter-based therapy, stand-alone surgical ablation is reasonable to restore sinus rhythm. The Cox-Maze III/IV lesion set is preferred for those with persistent or long-standing persistent AF.

Professional Statements and Societal Positions Guidelines

American College of Cardiology et al - 2019

In 2014, the American College of Cardiology, American Heart Association, and Heart Rhythm Society

(ACC/AHA/HRS) issued guidelines for the management of individuals with AF. In 2019, the AHA/ACC/HRS conducted a focused update of areas for which new evidence had emerged since the 2014 publication. Together, the guidelines included the following recommendations for rate control and rhythm control:

Rate Control:
- AV nodal ablation with permanent ventricular pacing is reasonable to control heart rate when pharmacological therapy is inadequate, and rhythm control is not achievable.
- AV nodal ablation with permanent ventricular pacing should not be performed to improve rate control without prior attempts to achieve rate control with medications.
Rhythm Control:
- AF catheter ablation is useful for symptomatic paroxysmal AF refractory or intolerant to at least one (1) class I or III antiarrhythmic medication when a rhythm-control strategy is desired.
- Before consideration of AF catheter ablation, assessment of the procedural risks and outcomes relevant to the individual is recommended.
- AF catheter ablation is reasonable for some individuals with symptomatic persistent AF refractory or intolerant to at least one (1) class I or III antiarrhythmic medication.
- In individuals with recurrent symptomatic paroxysmal AF, catheter ablation is a reasonable initial rhythm-control strategy before therapeutic trials of antiarrhythmic drug therapy, after weighing the risks and outcomes of drug and ablation therapy.
- AF catheter ablation may be considered for symptomatic long-standing (greater than or equal to 12 months) persistent AF refractory or intolerant to at least one (1) class I or III antiarrhythmic medication when a rhythm-control strategy is desired).
- AF catheter ablation may be considered before initiation of antiarrhythmic drug therapy with a class I or III antiarrhythmic medication for symptomatic persistent AF when a rhythm-control strategy is desired.
- AF catheter ablation should not be performed in individuals who cannot be treated with anticoagulant therapy during and after the procedure.
- AF catheter ablation to restore sinus rhythm should not be performed with the sole intent of obviating the need for anticoagulation.'
- AF catheter ablation may be reasonable in selected individuals with symptomatic AF and HF with reduced left ventricular (LV) ejection fraction (HFrEF) to potentially lower mortality rate and reduce hospitalization for HF

Although the guidelines did not make a specific recommendation on the use of cryoablation, they did state:

Cryoballoon ablation is an alternative to point-by-point radiofrequency ablation to achieve pulmonary vein isolation.

Society of Thoracic Surgeons - 2017

In 2017, the Society of Thoracic Surgeons published guidelines on the surgical treatment of atrial fibrillation (AF). Recommendations are as follows:

Surgical ablation for AF is recommended at the time of concomitant mitral operations to restore sinus rhythm.
Surgical ablation for AF is recommended at the time of concomitant isolated aortic valve replacement, isolated CABG surgery, and aortic valve replacement plus CABG operations to restore sinus rhythm.
Surgical ablation for symptomatic AF in the absence of structural heart disease that is refractory to class I/III antiarrhythmic drugs or catheter-based therapy of both is reasonable as a primary stand-alone procedure to restore sinus rhythm.
