The “Myth” of the False Positive Stress Echo
It has been more than 25 years since the first reports of the use of echocardiographic imaging in conjunction with stress testing for the diagnosis of coronary artery disease. Since…
Characteristics and Outcomes of Patients With Abnormal Stress Echocardiograms and Angiographically Mild Coronary Artery Disease (<50% Stenoses) or Normal Coronary Arteries
Background Abnormal cardiac stress imaging findings are not always associated with angiographically significant coronary artery disease. The outcomes of patients with such false-positive findings have not been extensively examined. The…
Dynamic Assessment of Right Ventricular Volumes and Function by Real-Time Three-Dimensional Echocardiography: A Comparison Study With Magnetic Resonance Imaging in 100 Adult Patients
Background The aim of this study was to validate a novel real-time three-dimensional echocardiographic (RT3DE) analysis tool for the determination of right ventricular volumes and function in unselected adult patients….
Diagnosing Left Ventricular Diastolic Dysfunction by Echocardiography: Reverend Bayes Lends a Hand
In recent years, the importance of heart failure with preserved ejection fraction has been increasingly recognized, and the demand for a simple, noninvasive, bedside test for validating this diagnosis has…
Clinical Value of Real-Time Three-Dimensional Echocardiography for Right Ventricular Quantification in Congenital Heart Disease: Validation With Cardiac Magnetic Resonance Imaging
Background The objective of this study was to test the feasibility, accuracy, and reproducibility of the assessment of right ventricular (RV) volumes and ejection fraction (EF) using real-time three-dimensional echocardiographic…
Do Additional Echocardiographic Variables Increase the Accuracy of E/e′ for Predicting Left Ventricular Filling Pressure in Normal Ejection Fraction? An Echocardiographic and Invasive Hemodynamic Study
Background There are few data on adding left atrial volume index (LAVi) or pulmonary artery systolic pressure (PAP) to the ratio of early mitral inflow to mitral annular velocity (E/e′)…
Speckle Tracking Echocardiography for Cardiac Resynchronization Therapy: Has the Right Ultrasound Technique Finally Been Found?
Over the past decade, cardiac resynchronization therapy (CRT) has changed the treatment of patients with end-stage heart failure. Currently, on the basis of the guidelines of the American Heart Association,…
Patent Foramen Ovale: Echocardiographic Detection and Clinical Relevance in Stroke
This article reviews the main clinical aspects of patent foramen ovale (PFO), such as its prevalence in the population, the diagnostic techniques to detect its presence, its role as a…
Reference Values for Right Ventricular Volumes and Ejection Fraction With Real-Time Three-Dimensional Echocardiography: Evaluation in a Large Series of Normal Subjects
Background The quantification of right ventricular (RV) size and function is of diagnostic and prognostic importance. Recently, new software for the analysis of RV geometry using three-dimensional (3D) echocardiographic images…
Imaging the Forgotten Chamber: Is the Devil in the Boundary?
It is well known that the evaluation of right ventricular (RV) volume and function by two-dimensional echocardiography has long been hampered by the complex three-dimensional (3D) shape of this chamber,…
