Atrial Fibrillation Recurrence Prediction
A Dual-Branch Deep Learning Network Integrating Structured Data and Large Language Model-Based Medical Text Features for Atrial Fibrillation Recurrence Prediction: A Retrospective, Multicenter Study
Source: ClinicalTrials.gov · Last updated 12 Mar 2026
Brief summary (registry, in English)
We aimed to develop an dual-branch deep learning network that integrates feature representations extracted from medical texts using large language models, with structured data features derived from perioperative records of AF ablation patients. This integrated approach provides novel clinical insights into risk prognosis and enhances strategies for post-procedural management in AF ablation.
