Multicenter StudyPercutaneous Transvenous Transseptal Transcatheter Valve Implantation in Failed Bioprosthetic Mitral Valves, Ring Annuloplasty, and Severe Mitral Annular Calcification.
This study sought to examine the feasibility, safety, and intermediate-term outcomes in patients undergoing percutaneous transvenous transcatheter mitral valve implantation in failed bioprosthesis, ring annuloplasty, and calcific mitral stenosis. ⋯ Transfemoral percutaneous transvenous mitral valve implantation in high-risk patients with degenerated bioprosthesis is safe, effective, and associated with rapid improvement in hemodynamics, short length of stays, and improved functional status. Percutaneous mitral valve implantation in patients with failed annuloplasty rings and severe MAC is a promising therapy with significant short-term morbidity and mortality that requires further study.

Multicenter Study Observational StudyClinical Implications of Leaks Following Left Atrial Appendage Ligation With the LARIAT Device.
The aim of this study was to evaluate the incidence and clinical implications of leaks (acute incomplete occlusion, early and late reopenings) following LAA ligation with the LARIAT device. ⋯ Incomplete occlusion of the LAA after LARIAT ligation is relatively common and may be associated with thromboembolic events. Proper long-term surveillance with careful TEE should be considered to detect leaks, which can be managed with either resumption of oral anticoagulation or percutaneous transcatheter closure.

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 Multicenter Study Comparative StudyEffect of Pre-Hospital Ticagrelor During the First 24 h After Primary Percutaneous Coronary Intervention in Patients With ST-Segment Elevation Myocardial Infarction: The ATLANTIC-H²⁴ Analysis.
The aim of this landmark exploratory analysis, ATLANTIC-H(24), was to evaluate the effects of pre-hospital ticagrelor during the first 24 h after primary percutaneous coronary intervention (PCI) in the ATLANTIC (Administration of Ticagrelor in the cath Lab or in the Ambulance for New ST elevation myocardial infarction to open the Coronary artery) study. ⋯ The effects of pre-hospital ticagrelor became apparent after PCI, with numerical differences in platelet reactivity and immediate post-PCI reperfusion, associated with reductions in ischemic endpoints, over the first 24 h, whereas there was a small excess of mortality. (Administration of Ticagrelor in the cath Lab or in the Ambulance for New ST elevation myocardial infarction to open the Coronary artery [ATLANTIC, NCT01347580]).

Multicenter Study Comparative Study1-Year Outcomes of Everolimus-Eluting Bioresorbable Scaffolds Versus Everolimus-Eluting Stents: A Propensity-Matched Comparison of the GHOST-EU and XIENCE V USA Registries.
The purpose of this study was to compare the 1-year outcomes of the ABSORB everolimus-eluting bioresorbable scaffold (BRS) (Abbott Vascular, Santa Clara, California) and the XIENCE everolimus-eluting stent (EES) (Abbott Vascular) in patients undergoing percutaneous coronary intervention. ⋯ In a contemporary large cohort of patients undergoing percutaneous coronary intervention with ABSORB BRS, the combined rate of ischemic events at 1 year was low and nonsignificantly different compared with matched patients treated with XIENCE EES.
