Comparative StudyRight Ventricular Systolic Function Responses to Acute and Chronic Pulmonary Hypertension: Assessment with Myocardial Deformation.
The distinction between right ventricular (RV) dysfunction due to an acute etiology (pulmonary embolism [PE]) or chronic afterload (pulmonary arterial hypertension [PAH]) has important therapeutic implications. The aim of this study was to test the hypothesis that RV remodeling would alter RV free wall strain (RVFWS) and differentiate chronic from acute RV afterload. ⋯ RVFWS is more predictive than RV end-diastolic area and less variable than FAC in distinguishing acute from chronic RV pressure overload. RVFWS adds incremental and independent information to standard measures of RV function in assessing the acuity of pulmonary hypertension.

Feasibility of Echocardiographic Techniques to Detect Subclinical Cancer Therapeutics-Related Cardiac Dysfunction among High-Dose Patients When Compared with Cardiac Magnetic Resonance Imaging.
Cardiac magnetic resonance imaging (CMR) is the gold standard for the quantification of global and regional myocardial function and can detect subclinical myocardial dysfunction in anthracycline-induced cardiomyopathy. The aim of this study was to ascertain reliable echocardiographic parameters that can be used for the early identification of cancer therapeutics-related cardiac dysfunction, compared with CMR. ⋯ Three-dimensional echocardiographic ejection fraction < 55%, end-systolic volume index > 29 mL/m(2), three-dimensional speckle-tracking echocardiographic peak global longitudinal strain magnitude < -17.5%, and a decrease in early atrial myocardial velocity at the interventricular septum of <10 cm/sec by Doppler tissue imaging are the most sensitive transthoracic echocardiographic parameters to identify subjects with subclinical myocardial dysfunction by CMR.

Intracardiac Doppler Echocardiography for Monitoring of Pulmonary Artery Pressures in High-Risk Patients Undergoing Transcatheter Aortic Valve Replacement.
Uncontrolled pulmonary hypertension may cause worse outcomes after transcatheter aortic valve replacement (TAVR), while hemodynamic monitoring is desirable for risk control. Pulmonary artery pressure (PAP) readings obtained by intracardiac Doppler echocardiography were evaluated. ⋯ Intracardiac Doppler echocardiography-derived monitoring of PAP by the mean gradient method is accurate and well applicable to high-risk TAVR candidates for intraprocedural risk control.

Multicenter StudyCardiovascular Health in Young Adulthood and Association with Left Ventricular Structure and Function Later in Life: The Coronary Artery Risk Development in Young Adults Study.
The aim of this study was to determine the association between cardiovascular health (CVH) in young adulthood and left ventricular (LV) structure and function later in life. ⋯ Greater levels of CVH in young adulthood are associated with lower LV mass and lower risk for diastolic dysfunction 25 years later.

Impact of Body Size on Inferior Vena Cava Parameters for Estimating Right Atrial Pressure: A Need for Standardization?
Inferior vena cava (IVC) diameter and its respiratory change, as determined using echocardiography, are commonly used to assess right atrial pressure (RAP). Despite the widespread use of the IVC approach for RAP assessment, the relations among body surface area (BSA), IVC diameter, and respirophasic change remain unclear. The aim of this study was to investigate the impact of BSA on IVC parameters for predicting elevated RAP. ⋯ Body size, measured as BSA, is important to consider when IVC diameter is used to assess RAP. The optimal cutoff point of IVCDmax was 21 mm for patients with larger BSAs and 17 mm for those with smaller BSAs. However, the cutoff point of IVC collapsibility was not influenced by the difference of BSA.
