Giant Thrombus on the Left Atrial Posterior Wall Following Pulsed-Field and Radiofrequency Ablation

This case report highlights that pulsed-field ablation with radiofrequency ablation of the LAPW can rarely lead to a giant LAPW thrombus in patients with persistent AF, severe left ventricular dysfunction, and an enlarged LA with a reduced LA-emptying fraction, and intensified oral anticoagulation may be necessary to manage the postablation thrombus.
