Strain and strain rate echocardiography is an emerging technique for assessing myocardial
systolic and diastolic function. It is envisioned that this modality could change the …

Characterization of tissue elasticity (stiffness) and viscosity has important medical
applications because these properties are closely related to pathological changes …

OBJECTIVES We propose a new method to easily quantify asynchronous wall motion due to
postsystolic shortening (PSS). We also studied the relationship of the spatial and temporal …

Background Takotsubo syndrome is an increasingly recognized cause of chest pain and
occasionally of cardiogenic shock. Despite rapid improvement of the left ventricular (LV) …

Background—In this study we evaluate the diastolic deformation of ischemic/reperfused
myocardium and relate this deformation to tissue elastic properties. Methods and Results …

Ultrasound tissue harmonic imaging is widely used to improve ultrasound B-mode imaging
quality thanks to its effectiveness in suppressing imaging artifacts associated with ultrasound …

Objectives: Time to onset of regional relaxation (TR) has been proposed as a novel index of
regional myocardial function. This study sought to prospectively establish the feasibility and …

Aims Ultrasound (US)-enhanced gene transfer for cardiovascular disease is an emerging
technique with translational relevance. Prior to pre-clinical applications, optimization of gene …

Viscoelastic properties of the myocardium are important for normal cardiac function and may
be altered by disease. Thus, quantification of these properties may aid with evaluation of the …

Background Early in the prevention and treatment of bioprosthetic valve thrombosis (BPVT),
anticoagulation is effective, but the long-term outcome after BPVT is unknown. Objectives …
