Electroanatomic Mapping System and Intracardiac-Echo to Guide Endomyocardial Biopsy

Area of Science:

• Cardiology
• Medical Imaging
• Interventional Procedures

Background:

• Endomyocardial biopsy (EMB) is crucial for diagnosing heart conditions but faces limitations.
• Its diagnostic yield is often hampered by sampling errors and procedural complications.
• Current use is restricted to specialized centers due to perceived invasiveness.

Purpose of the Study:

• To provide guidance on performing EMB using advanced imaging techniques.
• To review evidence supporting the combined use of EMB with electroanatomic voltage mapping and intracardiac echocardiography.
• To improve the diagnostic accuracy and safety of EMB.

Main Methods:

• Detailed technical and practical guidance for performing EMB.
• Integration of electroanatomic voltage mapping for precise myocardial targeting.
• Utilization of intracardiac echocardiography for real-time visualization during EMB.

Main Results:

• Precise localization of diseased myocardium minimizes sampling errors.
• Combined approach enhances the diagnostic yield of EMB.
• Improved procedural safety and reduced complications are anticipated.

Conclusions:

• Electroanatomic voltage mapping and intracardiac echocardiography significantly enhance EMB performance.
• This integrated strategy addresses key limitations of traditional EMB.
• Wider adoption of this technique can improve diagnosis and management of cardiac diseases.
