Why the study?
Does radiofrequency catheter ablation improve LV diastolic dysfunction, LA morphology, and mechanical function in patients with isolated atrial fibrillation?
Does radiofrequency catheter ablation improve LV diastolic dysfunction, LA morphology, and mechanical function in patients with isolated atrial fibrillation?
Restoration of sinus rhythm by catheter ablation in isolated AF leads to reverse remodeling of the left atrium and improvement in left ventricular diastolic and systolic functions.
No takes yet. Share an insight, caveat, or question.
May support ablation-related LA remodeling in isolated AF; hypothesis-generating, needs RCTs before practice change.
Réant et al. (2005) studied this question.
