Application of a Parametric Display of Two-Dimensional Speckle-Tracking Longitudinal Strain to Improve the Etiologic Diagnosis of Mild to Moderate Left Ventricular Hypertrophy
Background The distinction of hypertrophic cardiomyopathy (HCM) or cardiac amyloidosis (CA) from hypertensive heart disease may be difficult. The aim of this study was to determine the impact of parametric…
It’s Back to School Time at ASE
Neil J. Weissman, MD, FASE In every newspaper and in every store window, you can’t help being reminded that it is “Back to School” time of year. Remember those days?…
Feasibility and Reproducibility of Three-Dimensional Echocardiographic Assessment of Right Ventricular Size and Function in Pediatric Patients
Background Quantitative assessment of right ventricular (RV) size and function is important in congenital heart disease. Although three-dimensional (3D) echocardiography overcomes geometric challenges that limit two-dimensional echocardiography, its feasibility and…
Effect of Chronic Right Ventricular Volume Overload on Ventricular Interaction in Patients after Tetralogy of Fallot Repair
Background Right ventricular (RV) volume overload results in RV dilatation and dysfunction in patients with pulmonary regurgitation after tetralogy of Fallot (ToF) repair, affecting left ventricular (LV) function because of…
Reproducibility of Regional and Global Longitudinal Strains Derived from Two-Dimensional Speckle-Tracking and Doppler Tissue Imaging between Expert and Novice Readers during Quantitative Dobutamine Stress Echocardiography
Background Longitudinal strain (LS) is a quantitative parameter that adds incremental value to wall motion analysis. The aim of this study was to compare the reproducibility of LS derived from…
Left Ventricular Myocardial Strain by Three-Dimensional Speckle-Tracking Echocardiography in Healthy Subjects: Reference Values and Analysis of Their Physiologic and Technical Determinants
Background Despite growing interest in applying three-dimensional (3D) speckle-tracking echocardiography (STE) to measure left ventricular (LV) myocardial deformation in various diseases, normative values for 3D speckle-tracking echocardiographic parameters and the…
Mechanical Dyssynchrony after Cardiac Resynchronization Therapy for Severely Symptomatic Heart Failure Is Associated with Risk for Ventricular Arrhythmias
Background Risk factors for ventricular arrhythmias after cardiac resynchronization defibrillator therapy (CRT-D) for severely symptomatic heart failure are of clinical importance but are not clearly defined. The objective of this…
