JASE 2010— A Progress Report
While it will be February 2010 by the time that you read this Editor’s Page , I am writing it as 2009 winds down. It seems fitting to me, as…
Myocardial Contractile Inefficiency and Dyssynchrony in Heart Failure With Preserved Ejection Fraction and Narrow QRS Complex
Background Using speckle-tracking imaging (STI), the aims of this study were to assess dyssynchrony and quantify the myocardial energy wasted by contractility in delayed segments by determining the longitudinal strain…
Three-Dimensional Echocardiographic Assessment of Right Ventricular Volume and Function in Adult Patients With Congenital Heart Disease: Comparison With Magnetic Resonance Imaging
Background The aim of this study was to evaluate the accuracy of three-dimensional (3D) ultrasound compared with the standard magnetic resonance imaging method in determining right ventricular (RV) volumes and…
Right Ventricular Pacing from the Septum Avoids the Acute Exacerbation in Left Ventricular Dyssynchrony and Torsional Behavior Seen with Pacing from the Apex
Objective The study objective was to compare the left ventricular (LV) dyssynchrony and torsional behavior between right ventricular apical (RVA) and right ventricular septal (RVS) pacing. Methods Forty-six patients with…
Myocardial Contractile Function in the Region of the Left Ventricular Pacing Lead Predicts the Response to Cardiac Resynchronization Therapy Assessed by Two-Dimensional Speckle Tracking Echocardiography
Background The aim of this study was to test the impact of posterolateral myocardial systolic function on response to cardiac resynchronization therapy (CRT). Methods Forty patients were studied before and…
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…
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…
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…
