The myofiber geometry of the left ventricle (LV) changes gradually from a right-handed helix
in the subendocardium to a left-handed helix in the subepicardium. In this review, we …

Echocardiography plays an evolving and important role in the care of heart failure patients
treated with biventricular pacing, or cardiac resynchronization therapy (CRT). Numerous …

Objectives: This study sought to report full 1-year results, detailed magnetic resonance
imaging analysis, and determinants of efficacy in the prospective, randomized, controlled …

Background—Data from single-center studies suggest that echocardiographic parameters of
mechanical dyssynchrony may improve patient selection for cardiac resynchronization …

Background Cardiac resynchronization therapy (CRT) is one of the most successful heart
failure therapies to emerge in the last 25 years and is applicable to∼ 25–30% of patients …

Background—Mechanical dyssynchrony is a potential means to predict response to cardiac
resynchronization therapy (CRT). We hypothesized that novel echocardiographic image …

Objectives: The objective of this study was to assess the usefulness of each type of strain for
left ventricular (LV) dyssynchrony assessment and its predictive value for a positive …

Objectives: We evaluated the ability of delayed enhancement magnetic resonance imaging
(DE-MRI) to predict clinical response to cardiac resynchronization therapy (CRT) …

Cardiac dynamics are traditionally linked to a left ventricle, right ventricle, and septum
morphology, a topography that differs from the heart's five-century-old anatomic description …

OBJECTIVE: The two-dimensional speckle tracking (2DT) method is based on the
measurements of strain on two-dimensional (2D) images, ignoring actual three-dimensional …
