The left ventricular eccentricity as a predictor of postoperative cardiac performance in valvular heart diseases
Abstract:
A clear correlation expressed by the following equation was observed between the preoperative left ventricular end-systolic eccentricity (epsilon s) and the percentage change of the left ventricular dimension (% delta D) in chronic valvular heart diseases: % delta D = 88.37 epsilon s - 48.16 (r = 0.66, p less than 0.001). Therefore, epsilon s may function as an index for predicting the postoperative cardiac performance independent of the affected valvular locations and the morphology of the lesions.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
