Superior Prognostic Value of Right Ventricular Free Wall Compared to Global Longitudinal Strain in Patients With Heart Failure.

J Am Soc Echocardiogr 2019 Apr 9. Epub 2019 Apr 9.

Cardiology and Cardiovascular Pathophysiology, Azienda Ospedaliero-Universitaria "S. Maria della Misericordia", Perugia, Italy.

Background: Global right ventricular (RV) longitudinal strain (RVGLS) and free wall RV longitudinal strain (RVFWS) have both been advocated as sensitive tools to evaluate RV function and predict prognosis in patients with heart failure and reduced ejection fraction (HFrEF). However, because the interventricular septum is an integral part of the left ventricle (LV) also, RVGLS might be influenced by LV dysfunction. Thus, we compared the prognostic performance of either RV strain parameter in HFrEF patients, also taking into account the degree of LV systolic dysfunction. Read More

Revisiting Anatomy of the Interatrial Septum and its Adjoining Atrioventricular Junction Using Noninvasive Imaging Techniques.

J Am Soc Echocardiogr 2019 Feb 22. Epub 2019 Feb 22.

Cardiac Morphology Unit, Royal Brompton Hospital and Imperial College, London, United Kingdom.

Interest in the anatomy of the interatrial septum (IAS) and its adjoining atrioventricular (AV) junction has risen enormously in the past two decades with the simultaneous evolution of left-sided percutaneous structural heart disease and complex electrophysiologic procedures. These procedures require, in fact, a direct route to the left atrium through the IAS. Thus, a thorough understanding of the complex anatomy of the IAS and AV junction is essential for performing a safe and effective transseptal puncture. Read More

J Am Soc Echocardiogr 2019 Apr 25;32(4):484-494. Epub 2019 Jan 25.

University of Chicago Medical Center, Chicago, Illinois. Electronic address:

Background: Right ventricular (RV) function plays a pivotal prognostic role in multiple cardiac diseases. Echocardiography guidelines recommend that RV quantification be performed in the RV-focused view, which is theoretically more reproducible than the four-chamber (4Ch) view. However, differences between views in RV size and function measurements have never been systematically studied. Read More

Global Left Ventricular Relaxation: A Useful Echocardiographic Marker of Heart Transplant Rejection and Recovery in Children.

J Am Soc Echocardiogr 2019 Apr 22;32(4):529-536. Epub 2019 Jan 22.

The Heart Institute, Joe DiMaggio Children's Hospital at Memorial, Hollywood, Florida.

Background: Tissue Doppler velocities are impaired after heart transplantation and further diminished in acute rejection.

Methods: Left ventricular relaxation index (LVRI) was calculated as the sum of E' of the left ventricular lateral, septal and posterior walls divided by left ventricular posterior wall (LVPW) thinning (LVRI = E' lateral + E' septal + E' posterior/[systolic LVPW - diastolic LVPW/systolic LVPW]). On the basis of a prior study, LVRI > 0. Read More

Mitral Annular and Left Ventricular Dynamics in Atrial Functional Mitral Regurgitation: A Three-Dimensional and Speckle-Tracking Echocardiographic Study.

J Am Soc Echocardiogr 2019 Apr 21;32(4):503-513. Epub 2019 Jan 21.

Division of Cardiology, Department of Medicine and Therapeutics, Prince of Wales Hospital, The Chinese University of Hong Kong, Hong Kong, China. Electronic address:

Background: Patients with atrial fibrillation (AF) and left atrial (LA) enlargement may develop functional, normal leaflet motion mitral regurgitation (MR) without left ventricular (LV) remodeling. Mitral annular dynamics and LV mechanics are important for preserving normal mitral valve function. The aim of this study was to assess the annular and LV dynamics in patients with AF and functional MR. Read More

Speckle-Tracking Echocardiography in Children With Duchenne Muscular Dystrophy: A Prospective Multicenter Controlled Cross-Sectional Study.

J Am Soc Echocardiogr 2019 Mar 21;32(3):412-422. Epub 2019 Jan 21.

PHYMEDEXP, University of Montpellier, CNRS, INSERM, CHU Montpellier, Montpellier, France.

Background: Prognosis of Duchenne muscular dystrophy (DMD) is related to cardiac dysfunction. Speckle-tracking echocardiographic (STE) imaging is emerging as a noninvasive functional biomarker to consider in the early detection of DMD-related cardiomyopathy. However, STE analysis has not been assessed in a prospectively controlled study, especially in presymptomatic children with DMD, and no study has used STE analysis in all three displacements (longitudinal, radial, and circumferential) and for both ventricles.

Characterization of Medical Professional Liability Risks Associated With Transesophageal Echocardiography.

J Am Soc Echocardiogr 2019 Mar 21;32(3):359-364. Epub 2019 Jan 21.

Division of Science & Quality, American College of Cardiology, Washington, District of Columbia.

Background: Medical claim data offer the possibility to improve patient care and mitigate liability. Although published analyses exist in cardiology, no information is available for transesophageal echocardiography (TEE). In this study, the authors reviewed medical claims involving TEE to identify potential risk management concerns so that these lessons could be used to improve the safety and quality of transesophageal echocardiographic practice.
