Are arterial elastance and heart-arterial coupling in aortic regurgitation determined by aortic leak severity?
In AR, E(a) is determined by aortic leak severity rather than by arterial system properties. Using E(a)/E(max) as a coupling parameter in general or as a mechanico-energetic regulatory parameter in particular is questionable.
This study suggests that PVI values >9% during KT are associated with the occurrence of DGF.
