The Third Time Is a Charm: ASE Scientific Sessions 2012
Ken Horton RCS, FASE It’s hard to believe another year has flown by and we are right around the corner from the 2012 ASE Scientific Sessions. Hopefully, by now you…
In Vitro Atrial Septal Ablation Using High-Intensity Focused Ultrasound
Background High-intensity focused ultrasound (HIFU) has been applied clinically as a noninvasive therapeutic tool. Atrial septostomy is a palliative treatment for pulmonary artery hypertension. The purpose of this study was…
The Incremental Value of Valvuloarterial Impedance in Evaluating the Results of Transcatheter Aortic Valve Implantation in Symptomatic Aortic Stenosis
Background Valvuloarterial impedance ( Z va ) can estimate the global hemodynamic load on the left ventricle in patients with severe aortic stenosis better than the standard indexes, as shown…
Prognostic Value of Tricuspid Annular Tissue Doppler Velocity in Heart Failure with Atrial Fibrillation
Background Right ventricular function is associated with long-term outcomes of heart failure (HF), particularly with atrial fibrillation (AF). The aim of this study was to evaluate the prognostic value of…
Factors Affecting the Endothelial Retention of Targeted Microbubbles: Influence of Microbubble Shell Design and Cell Surface Projection of the Endothelial Target Molecule
Background In biologic systems, the arrest of circulating cells is mediated by adhesion molecules projecting their active binding domain above the cell surface to enhance bond formation and tether strength….
Ejection Fraction Change and Coronary Artery Disease Severity: A Vasodilator Contrast Stress-Echocardiography Study
Background An important goal of noninvasive stress testing is the identification of patients with left main coronary artery or three-vessel disease, because coronary artery disease extension and severity are major…
Assessment of Left Atrial Mechanics in Patients with Atrial Fibrillation: Comparison between Two-Dimensional Speckle-Based Strain and Velocity Vector Imaging
Background Two-dimensional (2D) speckle tracking–derived left atrial (LA) strain (ϵ) facilitates comprehensive evaluation of LA contractile, reservoir, and conduit function; however, its dependence on the individual software used for assessment…
Correction
In the article entitled “The Role of Echocardiography in the Management of Patients Supported by Extracorporeal Membrane Oxygenation” by Platts et al ( J Am Echocardiogr 2012;25:131-41), there was an error…
Three-Dimensional Mechanical Dyssynchrony and Myocardial Deformation of the Left Ventricle in Patients with Tricuspid Atresia after Fontan Procedure
Background The aim of this study was to test the hypothesis that dyssynchronous contraction of functional single ventricles occurs in Fontan patients and is related to indices of myocardial deformation…
Left Atrial Enlargement Is Associated with a Rapid Decline in Residual Renal Function in ESRD Patients on Peritoneal Dialysis
Background Left atrial (LA) volume index (LAVI) has been considered a stable indicator of diastolic dysfunction and an independent predictor of mortality in patients with end-stage renal disease. To date,…
