Abstract Background Quantitative regional strain analysis by speckle tracking echocardiography (STE) may be particularly useful in the assessment of myocardial ischemia and viability, although reliable measurement of regional strain remains challengi

Objective Tricuspid annular size reduction with annuloplasty rings represents the foundation of surgical repair of functional tricuspid regurgitation. However, the precise effect of annular size reduction on leaflet motion and geometry remains unknow

New Findings: What is the central question of this study? The length dependence of activation (LDA) is typically explained by a length-dependent increase in calcium sensitivity, but recently calcium-independent mechanisms have been suggested: does ac

Objectives This study sought to investigate how regional left ventricular (LV) function modifies septal motion in left bundle branch block (LBBB). Background In LBBB, the interventricular septum often has marked pre-ejection shortening, followed by i
