Why the study?
Does baseline renal function predict atrial fibrillation recurrence and abnormal atrial substrate in patients undergoing catheter ablation for paroxysmal AF?
Does baseline renal function predict atrial fibrillation recurrence and abnormal atrial substrate in patients undergoing catheter ablation for paroxysmal AF?
Decreased renal function is an independent predictor of abnormal left atrial substrate and higher AF recurrence rates after catheter ablation in patients with paroxysmal AF.
No takes yet. Share an insight, caveat, or question.
Lower eGFR may aid post-ablation risk stratification in paroxysmal AF; hypothesis-generating, prospective studies needed before practice change.
Chao et al. (2011) studied this question.
