Ventricular strain analysis in patients with no structural heart disease using a vendor-independent speckle-tracking software

BMC Cardiovascular Disorders, 2020
Background Ventricular strain measurements vary depending on cardiac chamber (left ventricle [LV] or right ventricle [RV]), type of strain (longitudinal, circumferential, or radial), ventricular level (basal, mid, or apical), myocardial layer ...

Additive effect of aortic regurgitation degree on left ventricular strain in patients with type 2 diabetes mellitus evaluated via cardiac magnetic resonance tissue tracking

Cardiovascular Diabetology, 2022
Background Type 2 diabetes mellitus causes left ventricular (LV) remodeling and increases the risk of aortic regurgitation (AR), which causes further heart damage.

Comprehensive Cardiovascular Magnetic Resonance‐Derived Myocardial Strain Analysis Provides Independent Prognostic Value in Acute Myocarditis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Late gadolinium enhancement and left ventricular (LV) ejection fraction on cardiovascular magnetic resonance (CMR) are prognostic markers, but their predictive value for incident heart failure or life‐threatening arrhythmias in acute ...

Reduced global longitudinal and radial strain with normal left ventricular ejection fraction late after effective repair of aortic coarctation - a CMR feature tracking study [PDF]

Journal of Cardiovascular Magnetic Resonance, 2012
We sought to determine whether global and regional left ventricular (LV) strain parameters were altered in repaired coarctation of the aorta (COA) with normal LV ejection fraction (EF) when compared with healthy adult controls, and whether such alterations were related to LV hypertrophy (LVH).

Examples of left ventricular global radial strain (LVGRS) and epicardial adipose tissue volumes (EATV) in 2 Amateur marathoners.

, 2022
A, E: the epicardial and pericardium boundaries were manually delineated at the short axis level of each atrium and the ventricle at the end of diastole, the yellow part between the red and green lines is the epicardial adipose tissue (EAT).

Obstructive and nonobstructive hypertrophic cardiomyopathy: Differences in global and segmental myocardial strain by cardiac magnetic resonance feature tracking

, 2021
Purpose: To evaluate any significant differences in myocardial strain between hypertrophic obstructive cardiomyopathy (HOCM) and nonobstructive ones (HNCM), as assessed by cardiac magnetic resonance feature tracking (CMR-FT). Materials and Methods: A
