The objective of this study was to evaluate the financial implications and the impact of pre-existing atrial fibrillation (AF) on in-hospital outcomes in patients who underwent transcatheter aortic valve implantation (TAVI) using the Nationwide Inpatient Sample (NIS) database. We identified patients who underwent TAVI from 2011 to 2014. The primary end point was the effect of pre-existing AF on in-hospital mortality. ⋯ After adjusting for patient- and hospital-level characteristics, pre-existing AF was not found to influence in-hospital mortality (odds ratio 1.05, 95% confidence interval 0.80 to 1.36). AF was associated with an increased risk of periprocedural cardiac complications (odds ratio 1.46, 95% confidence interval 1.22 to 1.75), longer LOS (p <0.001) and an increased cost of hospitalization (US$51,852 vs US$49,599). In conclusion, pre-existing AF did not impact in-hospital mortality in TAVI patients but was associated with increased cardiac complications, a longer hospital LOS, and a higher cost of hospitalization.

Meta Analysis Comparative Study
Meta-analysis of Randomized Controlled Trials on Patent Foramen Ovale Closure Versus Medical Therapy for Secondary Prevention of Cryptogenic Stroke.
The optimal management of patients with cryptogenic stroke (CS) and patent foramen ovale (PFO) remains controversial. We conducted a meta-analysis to assess the effect of PFO closure for secondary prevention of stroke on patients with CS. We searched the literature for randomized control trials assessing the recurrence of stroke after PFO closure compared with medical therapy (antiplatelet and/or anticoagulation). ⋯ There was no significant difference in all-cause mortality (RR 1.33, CI 0.56 to 3.16, p = 0.52, I2 = 0%), as well as no difference in bleeding risk between the 2 groups (RR 0.94, CI 0.49 to 1.83, p = 0.86, I2 = 29%). In conclusion, our meta-analysis demonstrates that PFO closure is associated with significantly lower risk of recurrent stroke in patients with PFO and CS compared with medical therapy. However, atrial fibrillation was more common among closure patients.
