Saddle shape of the mitral annulus reduces systolic strains on the P2 segment of the posterior mitral leaflet.

30 Oct 2009 BACKGROUND: The three-dimensional saddle shape of the mitral annulus is well characterized in animals and humans, but the impact of annular nonplanarity on valve function or mechanics is poorly understood. In this study, we investigated the impact ... Read more...

Recommendation of low-salt diet and short-term outcomes in heart failure with preserved systolic function.

30 Oct 2009 BACKGROUND: Dietary sodium indiscretion frequently contributes to hospitalizations in elderly heart failure patients. Animal models suggest an important role for dietary sodium intake in the pathophysiology of heart failure with preserved systolic ... Read more...

Abnormal regional left ventricular systolic and diastolic function in patients with coronary artery disease undergoing percutaneous coronary intervention: clinical significance of post-ischemic diastolic stunning.

18 Oct 2009 OBJECTIVES: This study was designed to characterize both regional left ventricular (LV) systolic and diastolic function after percutaneous coronary intervention by using strain imaging (SI) derived from 2-dimensional speckle-tracking ... Read more...
