Abstract
The purpose of this study is to investigate incidence of gastrointestinal symptoms and complications in patients who underwent high-power short-duration (HPSD), posterior left atrial wall isolation during atrial fibrillation ablation and thereafter have received gastrointestinal prophylactic regimen consisting of sucralfate, proton-pump inhibitor and colchicine. Patients were followed and assessed at baseline, up until 6th month following the procedures.Among 115 patients who were included, 5 patients (4.3%) reported gastrointestinal symptoms at follow-up. No complications were diagnosed during the follow-up. In conclusion, the HPSD along with prophylactic regimen has been associated with low incidence of gastrointestinal adverse events.
