Do left atrial size and left ventricular end-systolic dimension predict the progression of paroxysmal atrial fibrillation after RF catheter ablation?
Increased LA diameter and LV end-systolic dimension on echocardiogram predict the progression of paroxysmal AF after RF ablation, identifying a subgroup that may require more aggressive rhythm control therapies.
RF ablation prevents the progression of paroxysmal AF effectively, except in patients with increased LA diameter and LV end-systolic diameter on echocardiogram, suggesting more aggressive rhythm control therapies should be considered in these patients.
