The rapid technological developments of the past decade and the changes in echocardiographic practice brought about by these developments have resulted in the need for updated recommendations to the previously published guidelines for cardiac chamber quantification, which was the goal of the joint writing group assembled by the American Society of(More)

BACKGROUND Three-dimensional (3D) speckle-tracking echocardiography (STE) is an emerging technology used to quantify left ventricular (LV) function. However, the accuracy and normal values of LV strain and twist using 3D STE have not been established in a large group of normal subjects. The aims of this study were to (1) to evaluate the accuracy of 3D STE(More)
Cardiac involvement in amyloidosis has poor prognosis and its diagnosis is challenging because of its patchy, infiltrative nature. Echocardiography plays an important role in the diagnosis, management, and prognosis in this disease process. In this article, we briefly review the utility and problems associated with traditional echocardiographic techniques(More)
BACKGROUND Left ventricular (LV) ejection fraction (EF) by transthoracic two-dimensional echocardiography is time-intensive and highly dependent on image quality. Mitral annular displacement (MAD) qualitatively correlates with EF and can be measured in patients with poor image quality and dropout. The authors hypothesized that speckle-tracking(More)
BACKGROUND Echocardiographic speckle tracking strain has gained clinical importance. However, the comparability of measurements between different software systems is not well defined. METHODS In 47 healthy subjects left ventricular (LV) two-dimensional (2D) peak strain and time to peak strain (TTP) generated by EchoPAC (2DS) and velocity vector imaging(More)
BACKGROUND Right ventricular (RV) strain is a potentially useful prognostic marker in patients with pulmonary arterial hypertension (PAH). However, published reports regarding the accuracy of two-dimensional echocardiography (2DE)-derived RV strain against an independent reference in this patient population are limited. The aims of this study were: (1) to(More)
BACKGROUND Presurgical planning of mitral valve (MV) repair in patients with Barlow disease (BD) and fibroelastic deficiency (FED) is challenging because of the inability to assess accurately the complexity of MV prolapse. We hypothesized that the etiology of degenerative MV disease (DMVD) could be objectively and accurately ascertained using parameters of(More)
OBJECTIVES To determine the treatment and outcomes of a cohort of adults with the Fontan circulation diagnosed with intracardiac thrombus. BACKGROUND Formation of thrombus is common after the Fontan operation, albeit little has been published on the treatment and outcomes of these patients once they have developed an intracardiac thrombus. METHODS We(More)
