Two-year clinical outcome after a single cryoballoon ablation procedure: A comparison of first- and second-generation cryoballoons.
The ablation of paroxysmal atrial fibrillation (PAF) by cryoballoon has increased dramatically in recent years. However, there are few data comparing first- and second-generation cryoballoons. ⋯ CB-1 and CB-2 showed similar efficacy for PAF ablation, with similar arrhythmia recurrence 24 months after a single ablation procedure. However, our findings suggest that CB-2 may have more effective cooling capabilities, enabling shorter procedure and fluoroscopy times.

Multicenter StudyDeterminants of left atrial volume index in patients with aortic stenosis: A multicentre pilot study.
Left atrial (LA) enlargement is frequent in patients with aortic stenosis (AS), yet its determinants and prognostic implications are poorly understood. ⋯ LA enlargement is correlated with AS severity, but also with variables reflecting LV systolic and diastolic dysfunction. Further studies are needed to investigate the outcome implication of LA enlargement in patients with AS.
