Structured PICO

P

Population

Patients with cardiac arrhythmias undergoing invasive electrophysiological diagnostics and catheter ablation using three-dimensional non-fluoroscopic electroanatomical mapping systems.

I

Intervention

Three-dimensional non-fluoroscopic electroanatomical mapping and navigation systems (specifically CARTO / CARTO 3, Ensite NavX, and Rhythmia) utilizing activation mapping, voltage mapping, and complex fractionated atrial electrogram (CFAE) mapping

C

Comparator

Conventional fluoroscopy-guided electrophysiological mapping and ablation

Limitations

High financial cost of electroanatomical mapping systems and single-use catheters
Long learning curve and preparation time required for operators
Potential errors in geometry and electrogram interpretation due to inadequate or excessive catheter-myocardium contact
Inability of static 3D anatomical models to provide real-time visualization of acute mechanical complications (e.g., cardiac tamponade, hemothorax, pneumothorax)
Psychological barrier for surgeons transitioning from conventional 2D fluoroscopic views to 3D navigation models
High financial cost of systems and single-use proprietary catheters with limited working time
Long training curve and psychological barrier for operators accustomed to 2D fluoroscopy
Risk of mapping errors from poor catheter contact, excessive wall pressure, or insufficient point density
Inability to directly visualize real-time mechanical complications (such as hemopericardium, tamponade, or pneumothorax) without supplemental imaging
