Atrial Fibrillation
Conditions
Brief summary
The recurrence of atrial fibrillation(AF) after pulmonary vein ablation with cryoballoon is conducted by many factors . The previous studies found larger left atrial and longer AF duration are tied to higher risk of AF recurrence. The characters of ablation procedure is also of critical importance to durable clinical success such as temperature features and time-to-isolation (TTI). The aim of our study is to develop an tool of recurrence risk evaluation with both pre-procedure and procedure factors.
