Randomized Controlled Trial Comparative StudyCoronary Computed Tomography Angiography Versus Stress Echocardiography in Acute Chest Pain: A Randomized Controlled Trial.
This study sought to compare early emergency department (ED) use of coronary computed tomography angiography (CTA) and stress echocardiography (SE) head-to-head. ⋯ The use of SE resulted in the hospitalization of a smaller proportion of patients with a shorter length of stay than coronary CTA and was safe. SE should be considered an appropriate option for ED chest pain triage (Stress Echocardiography and Heart Computed Tomography [CT] Scan in Emergency Department Patients With Chest Pain; NCT01384448).

Myocardial Strain in Prediction of Outcomes After Surgery for Severe Mitral Regurgitation.
We investigated whether global longitudinal strain (GLS) is a better predictor of clinical events after surgery for mitral regurgitation (MR) than conventional parameters. ⋯ GLS appears to be a better predictor of cardiac events all-cause death than conventional parameters. Measuring preoperative GLS is helpful to predict post-operative outcome and determine optimal timing for surgery in patients with severe primary MR.

Comparative Study Observational StudyIntervention Versus Observation in Symptomatic Patients With Normal Flow Low Gradient Severe Aortic Stenosis.
The purpose of this study was to describe patients with severe symptomatic aortic stenosis with normal flow and low gradients and determine whether they benefit from intervention. ⋯ Symptomatic patients with an aortic valve area of ≤1.0 cm2, normal flow, and low gradient may benefit from intervention as opposed to conservative treatment.
