Diastology: What Does the New Updated Guideline Do for You?
Allan L. Klein, MD, FRCP (C), FACC, FAHA, FESC, FASE My wife recently said to me that the mitral “E’s and A’s” have been good to me over the years….
Pediatric Reference Values and ZScore Equations for Left Ventricular Systolic Strain Measured by Two-Dimensional Speckle-Tracking Echocardiography
Background In pediatric echocardiography, myocardial strain measurements are likely influenced by cardiac size and growth in healthy children. The application of this technique in clinical practice has been hampered by…
A New ZScore Curve of the Coronary Arterial Internal Diameter Using the Lambda-Mu-Sigma Method in a Pediatric Population
Background Several coronary artery Z score models have been developed. However, a Z score model derived by the lambda-mu-sigma (LMS) method has not been established. Methods Echocardiographic measurements of the…
Assessment of Ventricular Septal Defect Size and Morphology by Three-Dimensional Transthoracic Echocardiography
Background Morphologic description of ventricular septal defect (VSD) is mandatory before performing the newly developed transcatheter closure procedure. Inaccurate estimation of defect size has been reported using conventional two-dimensional (2D)…
Deficient Surrounding Rims in Patients Undergoing Transcatheter Atrial Septal Defect Closure
Background The influence of deficient rims surrounding atrial septal defects (ASDs) in patients undergoing transcatheter closure has yet to be clarified. The aim of this study was to assess the…
Differences in Characteristics, Left Atrial Reverse Remodeling, and Functional Outcomes after Mitral Valve Replacement in Patients with Low-Gradient Very Severe Mitral Stenosis
Background The discrepancy between planimetered mitral valve area (MVA) and mean diastolic pressure gradient (MDPG) has not been studied extensively in patients with mitral stenosis. The purpose of the present…
Left Atrial Function in Preclinical Diastolic Dysfunction: Two-Dimensional Speckle-Tracking Echocardiography–Derived Results from the BEFRI Trial
Background Patients with preclinical left ventricular (LV) diastolic dysfunction (DD) are prone to develop heart failure with preserved ejection fraction. Although left atrial (LA) enlargement and deterioration of LA function…
Serial Echocardiographic Assessment of Left Ventricular Filling Pressure and Remodeling among ST-Segment Elevation Myocardial Infarction Patients Treated by Primary Percutaneous Intervention
Background Acute myocardial infarction and remodeling of the left ventricle is associated with significant changes in systolic and diastolic echocardiographic derived indices. The investigators have tried to determine whether persistence…
Outcome by Exercise Echocardiography in Patients with Low Pretest Probability of Coronary Artery Disease
Background Recommendations for testing in patients with low pretest probability of coronary artery disease differ in guidelines from no testing at all to different tests. The aim of this study…
Detection of Obstructive Coronary Artery Disease Using Peak Systolic Global Longitudinal Strain Derived by Two-Dimensional Speckle-Tracking: A Systematic Review and Meta-Analysis
Background Global longitudinal strain (GLS) is well validated and has important applications in contemporary clinical practice. The aim of this analysis was to evaluate the accuracy of resting peak GLS…
