Posterosuperior Bundle Pacing for Prevention of Atrial Fibrillation in Patients With Sinus Node Dysfunction (PSB-AF)

Descrizione dettagliata
Sinus node dysfunction (SND) is a common indication for permanent pacemaker implantation. Conventional right atrial appendage (RAA) pacing may result in delayed or dyssynchronous atrial activation, potentially increasing the risk of atrial arrhythmias. Posterosuperior bundle (PSB) pacing is a novel physiological atrial pacing approach. This study is a prospective, multicenter, open-label, randomized controlled trial. A total of approximately 300 eligible SND patients indicated for pacemaker implantation will be enrolled and randomly assigned (1:1) to PSB pacing or RAA pacing. Ventricular pacing will be performed using left bundle branch area pacing in both groups. Participants will be followed at 3, 6, 12, and 24 months after implantation. An interim analysis will be conducted after 100 patients complete the 6-month follow-up.
The primary endpoint is the occurrence of AF episodes lasting ≥6 minutes. Secondary endpoints include atrial high-rate episodes, AF burden, pacing parameters, ECG and echocardiographic indices, laboratory findings, and mortality outcomes. Safety endpoints include procedural complications and device-related adverse events.
