Multicenter Study Observational StudyPrevalence and Impact of Atrial Fibrillation in Patients With Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Replacement: An Analysis From the SOURCE XT Prospective Multicenter Registry.
The aims of this study were to assess the epidemiology of atrial fibrillation (AF) in patients treated with transcatheter aortic valve replacement (TAVR) and included in the large prospective SOURCE XT (SAPIEN XT Aortic Bioprosthesis Multi-Region Outcome Registry) study and to evaluate their outcomes according to the presence of pre-existing or new-onset AF (NOAF) (defined as AF occurring within 30 days after TAVR). ⋯ In the large dataset of the SOURCE XT registry, the presence of either pre-existing or NOAF increased all-cause and cardiac mortality and bleeding events. NOAF was associated with increased stroke rates at long-term follow-up.

Randomized Controlled Trial Comparative StudyImpact of Access Site on Bleeding and Ischemic Events in Patients With Non-ST-Segment Elevation Myocardial Infarction Treated With Prasugrel: The ACCOAST Access Substudy.
This study assessed whether the choice of vascular access site influenced outcomes among non-ST-segment elevation myocardial infarction (NSTEMI) patients enrolled in the ACCOAST (A Comparison of prasugrel at the time of percutaneous Coronary intervention Or as pre-treatment At the time of diagnosis in patients with non-ST-segment elevation myocardial infarction NCT01015287). ⋯ In the ACCOAST trial, TFA did not significantly increase TIMI major bleeding, although TRA was associated with a reduction in TIMI major or minor bleeding. Further study is needed to determine whether wider application of radial approach to NSTE-ACS patients at high risk for bleeding improves overall outcomes. (A Comparison of Prasugrel at PCI or Time of Diagnosis of Non-ST Elevation Myocardial Infarction [ACCOAST]; NCT01015287).
