Renal impairment is associated with poor prognosis in the setting of atrial fibrillation (AF). While AF catheter ablation is an effective treatment modality for AF burden reduction and improvement of symptoms, changes in renal function after catheter ablation and their association with rhythm outcome have not been studied in a large contemporary AF ablation cohort. ⋯ In patients after AF catheter ablation, eGFR changes during mid-term follow-up are associated with AF recurrences, CHADS2 and CHA2DS2-VASc scores.

Multicenter Study
Device-dependent association between paravalvar aortic regurgitation and outcome after TAVI.
The aim of the current study was to identify predictors of paraprosthetic aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) and examine its influence on short/medium-term mortality using the UK TAVI Registry. TAVI is an effective treatment for high-risk patients with severe symptomatic aortic stenosis (AS), but paraprosthetic AR has been associated with increased in-hospital and mid-term mortality. ⋯ Our data suggest that a large aortic annulus, high preprocedural transaortic gradient, and use of the self-expanding valve predict moderate-severe AR after TAVI. Such a degree of AR is associated with a significantly worse outcome with the balloon-expandable, but not with the self-expanding valve. Further studies are needed to verify this and explore potential mechanisms.

Multicenter Study
Two decades of experience with the Ross operation in neonates, infants and children from the Italian Paediatric Ross Registry.
Children undergoing Ross operation were expected to have longer autograft, but shorter homograft durability compared with adults. In order to define the outcome in the second decade after Ross operation in children, a nationwide review of 23 years of experience was undertaken. ⋯ Despite low hospital risk and satisfactory late survival, paediatric Ross operation bears substantial valve-related morbidity in the first two decades. Contrary to expectation, autograft reoperation is more common than homograft.

Randomized Controlled Trial Multicenter Study
Prevalence, characteristics and outcome of non-cardiac chest pain and elevated copeptin levels.
Copeptin, a quantitative marker of endogenous stress, seems to provide incremental value in addition to cardiac troponin in the early rule-out of acute myocardial infarction (AMI). Prevalence, characteristics and outcome of acute chest pain patients with causes other than AMI and elevated copeptin are poorly understood. ⋯ Elevated levels of copeptin are present in about one in five patients with non-cardiac chest pain and are associated with aging, cardiac and non-cardiac comorbidities as well as mortality.
