Why the study?
While clinical trial data have shown non-inferiority of pulsed field ablation compared with thermal ablation for AF, its safety profile is still being understood as registry data demonstrate different complications.
Pulsed field ablation for atrial fibrillation presents a unique safety profile compared to traditional thermal ablation, requiring specific awareness and preventive strategies for complications like coronary artery spasm and hemolysis.

Requires clinician vigilance for PFA-specific risks in AF ablation; challenges consensus on superior safety and leaves open randomized confirmation.
Pulsed field ablation (PFA) for AF has changed the landscape of AF treatment globally. While clinical trial data have shown non-inferiority compared with thermal ablation, the safety profile of this technology is still being understood. Large post-approval registry data are now accumulating and have invariably demonstrated that rather than PFA being necessarily safer than conventional thermal ablation, the safety profile is simply different. Pericardial tamponade remains a risk and may even be greater compared with thermal ablation. Coronary artery spasm has been recognised, particularly with off-label use of PFA. Haemolysis and associated acute kidney injury are unique complications related to PFA. Stroke risk persists with likely multiple causes. Other complications, such as femoral venous injury, vagal responses and transient phrenic nerve injury, are increasingly recognised. In this review, we summarise recent data regarding potential complications associated with PFA, including mechanisms, risk factors, management and prevention.
