National trends in heart failure hospital stay rates, 2001 to 2009.
This study sought to analyze recent trends over time in heart failure (HF) hospital stay rates, length of stay (LOS), and in-hospital mortality by age groups with a large national dataset of U.S. hospital discharges. ⋯ Younger patients have not experienced comparable declines in HF hospital stay, LOS, and in-hospital mortality as older patients. Black men remain a vulnerable population for HF hospital stay.

Multicenter StudyThe influence of left ventricular ejection fraction on the effectiveness of cardiac resynchronization therapy: MADIT-CRT (Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy).
The aim of this study was to evaluate the relationship between left ventricular (LV) ejection fraction and clinical outcome to cardiac resynchronization therapy (CRT) in mild heart failure patients enrolled in MADIT-CRT [corrected]. ⋯ In MADIT-CRT, the clinical benefit of CRT was evident regardless of baseline LVEF, including those with LVEF >30%, whereas the echocardiographic response was increased with increasing LVEF, indicating that CRT might benefit patients with better LVEF. (Multicenter Automatic Defibrillator Implantation With Cardiac Resynchronization Therapy [MADIT-CRT]; NCT00180271).

Comparative StudyAortic annular sizing for transcatheter aortic valve replacement using cross-sectional 3-dimensional transesophageal echocardiography.
This study compared cross-sectional three-dimensional (3D) transesophageal echocardiography (TEE) to two-dimensional (2D) TEE as methods for predicting aortic regurgitation after transcatheter aortic valve replacement (TAVR). ⋯ Cross-sectional 3D echocardiographic sizing of the aortic annulus dimension offers discrimination of post-TAVR paravalvular AR that is significantly superior to that of 2D-TEE. Cross-sectional data should be sought from 3D-TEE if good CT data are unavailable for TAVR sizing.

Meta AnalysisOutcomes after coronary computed tomography angiography in the emergency department: a systematic review and meta-analysis of randomized, controlled trials.
The aim of the study was to systematically review and perform a meta-analysis of randomized, controlled trials of coronary computed tomography angiography (CCTA) versus usual care (UC) triage of acute chest pain in the emergency department (ED). ⋯ Compared with UC, the use of CCTA in the ED is associated with decreased ED cost and length of stay but increased ICA and revascularization.
