ACR Appropriateness Criteria® Preprocedural Planning for Left Atrial Procedures in Atrial Fibrillation

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Atrial fibrillation necessitates various interventions, including endovascular treatments and cardioversion.
• Selecting appropriate preprocedural imaging is crucial for successful patient outcomes.
• Existing guidelines lack specific imaging recommendations for certain atrial fibrillation procedures.

Purpose of the Study:

• To summarize literature and provide evidence-based recommendations for preprocedural imaging selection.
• To address imaging needs in three key clinical scenarios: radiofrequency ablation, left atrial appendage occlusion, and cardioversion.
• To guide clinicians in choosing the most appropriate imaging modality for each scenario.

Main Methods:

• Systematic review of relevant medical literature.
• Application of the American College of Radiology Appropriateness Criteria methodology.
• Utilizing the RAND/UCLA Appropriateness Method for evidence evaluation.
• Incorporating expert opinion when literature is limited or equivocal.

Main Results:

• Imaging appropriateness is rated as 'usually appropriate,' 'may be appropriate,' or 'usually not appropriate' for each clinical scenario.
• Specific recommendations are provided for preprocedural imaging before radiofrequency ablation.
• Guidance is offered for imaging prior to left atrial appendage occlusion and cardioversion.

Conclusions:

• The document provides a structured approach to selecting preprocedural imaging for atrial fibrillation interventions.
• Evidence-based ratings assist in optimizing the use of diagnostic imaging modalities.
• The recommendations aim to improve the efficacy and safety of endovascular treatments and cardioversion for atrial fibrillation.
