EFFICACY AND SAFETY OF HIGH-POWER SHORT-DURATION RADIOFREQUENCY ABLATION FOR ATRIAL FIBRILLATION
Main Article Content
Abstract
Background: Atrial fibrillation (AF) is a common arrhythmia associated with increased risks of stroke and heart failure. Radiofrequency ablation is an effective treatment method, with the high-power short-duration (HPSD) technique gaining attention due to its ability to create more homogeneous lesions and shorten procedure time.
Objective: To evaluate the preliminary efficacy and safety of HPSD ablation for atrial fibrillation at Cho Ray Hospital.
Methods: Retrospective cohort study.
Results: A total of 37 patients were enrolled; 68.4% were male, with a mean age of 54.0 ± 12.4 years. Paroxysmal AF accounted for 56.7% of cases. Complete isolation of all four pulmonary veins and restoration of sinus rhythm were achieved in all patients (100%). The median procedure time was 160 minutes (interquartile range: 142–186), with a pulmonary vein isolation time of 83 minutes (60–112) and a mean fluoroscopy time of 11.5 ± 4.6 minutes. Additional carina ablation was required in 37.8% of patients to achieve complete conduction block. Acute complications were infrequent, with no cases of esophageal injury, stroke, or procedural mortality.
Conclusion: High-power short-duration ablation for atrial fibrillation is an effective and safe method that helps optimize procedural workflow and reduce complications.
