We appreciate the interest of Dr. Silbiger and the opportunity to address his comments. It is well recognized that patients with impaired relaxation patterns can have increased left ventricular (LV)…
Normal Values for Left Ventricular Volume in Infants and Young Children: Questions for the Authors
We read with interest the recent article by Lytrivi et al. and would like to thank the investigators for this important reference material. For clarification, we hope that they will respond…

We appreciate the comments of Dr. Feigenbaum, which allow us to discuss some aspects of the deliberations of the writing group that did not make it into print. As with…
Early Detection of Left Atrial Strain Abnormalities by Speckle-Tracking in Hypertensive and Diabetic Patients with Normal Left Atrial Size
Background Systemic hypertension and type 2 diabetes mellitus are associated with impaired left atrial (LA) function, but whether LA functional abnormalities also occur in patients with hypertension and diabetes who…
Coronary Artery Plaque Burden Does Not Affect Left Ventricular Diastolic Function in Asymptomatic Adults with Normal Ejection Fraction
Background Coronary artery disease (CAD) is commonly cited as a mechanism underlying diastolic dysfunction. However, the association of CAD without ischemia and left ventricular (LV) diastolic dysfunction has not been…
Right Ventricular Myocardial Systolic and Diastolic Dysfunction in Heart Failure with Normal Left Ventricular Ejection Fraction
Objective We hypothesized that in patients with heart failure with normal left ventricular (LV) ejection fraction (HFNEF), the same fibrotic processes that affect the subendocardial layer of the LV could…
The Value of Three-Dimensional Echocardiography Derived Mitral Valve Parametric Maps and the Role of Experience in the Diagnosis of Pathology
Background Accurate segmental mitral valve (MV) analysis is essential for surgical planning. Although real-time three-dimensional (3D) transesophageal echocardiography has improved the ability to visualize the MV, accurate localization of MV…
Reproducibility and Inter-Vendor Variability of Left Ventricular Deformation Measurements by Three-Dimensional Speckle-Tracking Echocardiography
Background Myocardial deformation measurements using two-dimensional speckle-tracking echocardiography (STE) are known to vary among vendors. The intervendor agreement of three-dimensional (3D) deformation indices has not been studied. The goals of…
Feasibility of Intraoperative Three-Dimensional Transesophageal Echocardiography in the Evaluation of Right Ventricular Volumes and Function in Patients Undergoing Cardiac Surgery
Background The aim of this study was to test the feasibility of the assessment of right ventricular (RV) volumes and function using real-time three-dimensional (3D) transesophageal echocardiographic (TEE) imaging in…
Feasibility of Single-Beat Full-Volume Capture Real-Time Three-Dimensional Echocardiography and Auto-Contouring Algorithm for Quantification of Left Ventricular Volume: Validation with Cardiac Magnetic Resonance Imaging
Background With recent developments in echocardiographic technology, a new system using real-time three-dimensional echocardiography (RT3DE) that allows single-beat acquisition of the entire volume of the left ventricle and incorporates algorithms…
