Is a direct surgical subxiphoid epicardial approach feasible for mapping and ablation in patients with difficult pericardial access?
A direct surgical subxiphoid approach provides a feasible alternative for epicardial mapping and ablation in patients with difficult pericardial access.
A direct surgical subxiphoid epicardial approach in the electrophysiology laboratory is feasible for patients with difficult pericardial access who require ablation of epicardial arrhythmia foci.
Soejima et al. (2004) studied this question.
