The editors and staff of the Journal of the American Society of Echocardiography ( JASE ) know that many of you look forward to receiving your paper copy of the…
Second Trimester Ultrasound: Reference Values for Two-Dimensional Speckle Tracking–Derived Longitudinal Strain, Strain Rate and Time to Peak Deformation of the Fetal Heart
Background Data on myocardial deformation during the internationally widely used second-trimester screening are scarce and confusing. Reference values of time to peak strain are missing. The aims of this study…
Value of Tricuspid Annular Plane Systolic Excursion and Peak Systolic Velocity in Children with Pulmonary Hypertension
We read with interest the article “Value of Tissue Doppler Echocardiography in Children With Pulmonary Hypertension” by Lammers et al. In our opinion, this is a very interesting report describing right…
Statement on Matching Language to the Type of Evidence Used in Describing Outcomes Data
There are many different types of studies that can be conducted to provide evidence for clinical and outcomes research, including but not limited to retrospective observational analyses, case-control studies, and…
Left Atrial Strain Is Reduced in Patients with Atrial Fibrillation, Stroke or TIA, and Low Risk CHADS 2Scores
Background Left atrial (LA) strain as a marker for discrimination of risk for stroke and transient ischemic attack (TIA) in patients with atrial fibrillation and low-risk CHADS 2 scores (≤1)…
Measurement of Left Atrial Volume from Transthoracic Three-Dimensional Echocardiographic Datasets Using the Biplane Simpson’s Technique
Background Although left atrial volume (LAV) by two-dimensional (2D) echocardiography provides prognostic information, the misalignment of the 2D cutting plane of the left atrium could make the measurements inaccurate. The…
Contractile Reserve Assessed by Three-Dimensional Global Circumferential Strain as a Predictor of Cardiovascular Events in Patients with Idiopathic Dilated Cardiomyopathy
Background It has been suggested that the assessment of left ventricular contractile reserve during dobutamine infusion can improve prognostic evaluation for patients with idiopathic dilated cardiomyopathy (DCM). However, the assessment…
Two-Dimensional Longitudinal Strain Assessment in the Presence of Myocardial Contrast Agents Is Only Feasible with Speckle-Tracking after Microbubble Destruction
Background Longitudinal strain (LS) imaging is an important tool for the quantification of left ventricular function and deformation, but its assessment is challenging in the presence of echocardiographic contrast agents…
Right Ventricular Morphology and Function in Top-Level Athletes: A Three-Dimensional Echocardiographic Study
Background Our objective was to explore the right ventricular (RV) dimensions and function and the effect of long-term intensive training in a large population of top level athletes using real-time…
E/e′ Two Weeks after Onset Is a Powerful Predictor of Cardiac Death and Heart Failure in Patients with a First-Time ST Elevation Acute Myocardial Infarction
Background Early transmitral flow velocity (E) divided by early diastolic velocity of the mitral valve annulus (e′) is referred to as the E/e′ ratio, a variable that strongly correlates with…
