Perioperative Imaging to Guide Epicardial Mapping and Ablation

Area of Science:

• Cardiology
• Electrophysiology
• Cardiac Anatomy

Background:

• Ventricular arrhythmias in Chagas disease necessitate minimally invasive treatment options.
• Epicardial access is now standard for arrhythmias unresponsive to endocardial ablation.
• Understanding pericardial anatomy is vital for advanced cardiac procedures.

Purpose of the Study:

• To highlight the importance of percutaneous epicardial access.
• To emphasize the role of epicardial access in treating various arrhythmias.
• To underscore the necessity of understanding pericardial anatomy for electrophysiologists.

Main Methods:

• The study reviews the evolution and application of the dry percutaneous epicardial access approach.
• It discusses the anatomical considerations for accessing the epicardial space.
• Case examples of treating ventricular arrhythmias and accessory pathways are implicitly referenced.

Main Results:

• Percutaneous epicardial access provides a viable alternative to sternotomy or pericardial windows.
• This approach is effective for managing ventricular arrhythmias in diverse cardiomyopathies.
• It is also used for atrioventricular accessory pathways post-failed endocardial ablation.

Conclusions:

• Percutaneous epicardial access is a critical advancement for treating refractory arrhythmias.
• A comprehensive understanding of pericardial anatomy is essential for successful epicardial interventions.
• This technique expands treatment options for complex cardiac conditions.
