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...

Ankle peak systolic velocity: new parameter to predict nonhealing in diabetic foot lesions.

30 Aug 2009 The objective of this study was to determine whether ankle peak systolic velocity (APSV) can predict nonhealing in diabetic foot lesions. Diabetic patients referred for duplex scanning of the lower extremity arteries were included if they had foot ... Read more...

Impact of prosthetic mitral rings on aortomitral apparatus function: a cardiac magnetic resonance imaging study.

30 Aug 2009 BACKGROUND: The circumference of the aortic annulus adjusts proportionally with changes in left ventricular volume. These dimensional changes in the aortic annulus improve the left ventricular outflow tract (LVOT) hemodynamics and enhance the ... Read more...
