Pulsed Field Ablation Versus Radiofrequency Ablation: Effects of Pulmonary Vein Isolation Combined With Left Atrial Posterior Wall Isolation on Postoperative Gastric Motility in Patients With Persistent Atrial Fibrillation (PFA-GM)
A Comparative Study on the Effects of Pulmonary Vein Isolation Combined With Left Atrial Posterior Wall Isolation Via Pulsed Field Ablation Versus Radiofrequency Ablation on Postoperative Gastric Motility in Patients With Persistent Atrial Fibrillation
This is a single-center, prospective, matched cohort study comparing the effect of Pulsed Field Ablation (PFA) versus Radiofrequency Ablation (RF) on postoperative gastric motility in patients with persistent atrial fibrillation (AF). A total of 20 patients will be enrolled in a 1:1 matched design (10 PFA, 10 RF), matched by age, gender, left atrial diameter, AF duration, and diabetes history. All patients will undergo pulmonary vein isolation (PVI) plus left atrial posterior wall isolation (LAPWI).
The primary outcome is gastric emptying assessed by radionuclide imaging preoperatively and at 48 hours post-ablation. Secondary outcomes include gastrointestinal symptom scores: PAGI-SYM, GSRS, and GerdQ measured before ablation and at 7 days post-procedure.
Patients with prior AF ablation, upper gastrointestinal surgery, gastroparesis, or recent use of gastrointestinal medications are excluded. The study period is from January 30, 2026 to July 30, 2026.
This study aims to evaluate whether PFA is associated with better gastric motility preservation compared with conventional RF ablation in persistent AF patients undergoing extended PVI plus posterior wall isolation.

Gastric Motility After Pulsed Field Versus Radiofrequency Ablation
기간: Preoperatively and at 48 hours post-ablation
|
Gastric emptying function will be assessed by radionuclide gastric emptying scintigraphy.
The primary outcome is the difference in the percentage of gastric retention at 2 hours postprandial between the pulsed field ablation (PFA) group and the radiofrequency ablation (RF) group, measured preoperatively and at 48 hours post-ablation.
