Strain and strain rate imaging: a promising tool for evaluation of ventricular function

Evaluation of left ventricular function with strain/strain rate imaging in patients with rheumatic mitral stenosis.

OBJECTIVE The most important sequel of acute rheumatic fever is mitral stenosis in long-term. The aim of the study is to determine left ventricular (LV) functions by tissue Doppler imaging (TDI) and strain/strain rate echocardiography (SE/SRE) in mitral stenosis patients who had no clinical signs of heart failure. METHODS Our study was designed as cross-sectional study. The study population c...

myocardial strain and strain rate imaging: comparison between doppler derived strain imaging and speckle tracking echocardiography

New two-dimensional global longitudinal strain and strain rate imaging for assessment of systemic right ventricular function.

OBJECTIVES To determine the usefulness of new two-dimensional strain indices, based on speckle tracking imaging, for assessment of systemic right ventricular (RV) function after an atrial switch operation for transposition of the great arteries. DESIGN Cross-sectional study. SETTING Tertiary paediatric cardiac centre. METHODS 26 patients, mean (SD) age 21.0 (3.6) years at 19.9 (3.2) years...

Tissue velocities, strain, and strain rate for echocardiographic assessment of ventricular function in congenital heart disease.

During the last decade tissue Doppler and myocardial deformation imaging has been introduced to quantify myocardial function in patients with congenital heart disease. These methods could have potential benefits for patients where the anatomy makes it difficult to quantify ventricular function using M-mode or two-dimensional volumetric techniques. In this overview, the potential benefits as wel...

assessment of right ventricular function by tissue doppler, strain and strain rate imaging in patients with left-sided valvular heart disease and pulmonary hypertension

background pulmonary artery hypertension is the presentation of various types of cardiovascular and systematic diseases. there are different kinds of noninvasive methods to determine right ventricular function, pulmonary artery pressure, and effect of pulmonary hypertension on right ventricular function. these methods include the tissue doppler imaging (tdi) of the tricuspid annulus and the lon...
