Cryoballoon versus radiofrequency catheter ablation of paroxysmal atrial fibrillation: Biomarkers of myocardial injury, recurrence rates, and pulmonar

• ...Interestingly, postprocedure troponin T measurements are higher in patients who undergo radiofrequency ablation compared to those who undergo cryoballoon ablation [33]...
• ...Accordingly, recurrence of pulmonary vein conduction following cryoballoon ablation is most common at the inferior segment of the pulmonary vein compared with radiofrequency ablation (74% vs. 17%, p=0.004) [33]...
• ...Most investigators have adopted a strategy of pacing the right phrenic nerve from the superior vena cava during ablation of the right-sided veins, especially the right superior pulmonary vein [33]...
