Right Atrial Speckle Tracking Strain Echocardiography in HeartFailure

Abnormal atrial strain with speckle-tracking echocardiography predicts the arrhythmic substrate of atypical right atrial flutter

This is an op under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4 Introduction Atypical atrial flutter is defined as macroreentrant atrial tachycardia (AT) that does not involve the cavotricuspid isthmus; a variety of reentrant circuits may include reentry around the mitral valve annulus or scar tissue w...

Right atrial function with speckle tracking echocardiography: Do we really need it?

Atrial septal defect (ASD) is one of the most common congenital cardiac anomalies presenting in adulthood. ASD is characterized by a defect in the interatrial septum that allows pulmonary venous return from the left atrium to pass directly to the right atrium. The magnitude of the left-toright shunt across the ASD depends on the defect size, the relative compliance of the ventricles, and the re...

Sex- and Method-Specific Reference Values for Right Ventricular Strain by 2-Dimensional Speckle-Tracking Echocardiography.

BACKGROUND Despite the fact that assessment of right ventricular longitudinal strain (RVLS) carries important implications for patient diagnosis, prognosis, and treatment, its implementation in clinical settings has been hampered by the limited reference values and the lack of uniformity in software, method, and definition used for measuring RVLS. Accordingly, this study was designed to establi...

Interatrial block and atrial remodeling assessed using speckle tracking echocardiography

BACKGROUND To evaluate the possibility of left atrial (LA) remodeling using speckle tracking echocardiography (STE) in patients with interatrial block (IAB). METHODS We performed a cross-sectional study with three groups of patients: 56 without IAB, 21 with partial IAB (pIAB), and 22 with advanced IAB (aIAB). Transthoracic echocardiographic (TTE) STE was performed and clinical and echocardiog...
