Dry Pericardial Access Enables Definitive Treatment of Septopulmonary Bundle–Mediated Roof-Dependent Flutter
Complex epicardial fiber architecture of the left atrium-particularly the SPB-may constitute key components of roof-dependent re-entry after AF ablation. Recognizing epicardial involvement helps identify the true circuit and can improve both procedural safety and efficacy when endocardial lesions are insufficient. Consider an epicardial approach when mapping and entrainment suggest SPB-mediated conduction that circumvents the roof line.
