The influence of sex on the prognosis of patients undergoing aortic valve replacement for severe stenosis is unclear. Nevertheless, a number of studies have regarded sex as an independent risk factor. The aim of this study was to evaluate the influence of sex on perioperative outcomes in patients undergoing valve replacement for severe aortic stenosis. ⋯ Perioperative mortality in women with severe aortic stenosis who underwent valve replacement was high. However, after adjustment for potential confounding factors, particularly body surface area, female sex was not an independent risk factor for mortality.

Multicenter Study
Low-dose dobutamine gated-SPECT analysis of left ventricular segmental wall thickening in ischemic cardiomyopathy.
The objective of this study was to use low-dose dobutamine (LDD) gated single-photon emission computed tomography (SPECT) to evaluate segmental thickening of the left ventricle (LV) and its relationship with changes in ejection fraction (EF) and ventricular volumes in patients with ischemic cardiomyopathy. ⋯ During the assessment of global left ventricular contractile reserve by LDD gated-SPECT, attention should be paid not only to the behavior of segments with severely decreased baseline thickening, which are generally regarded as indicating viability, but also to segments with mild-to-moderate alterations and to those in which thickening decreases.
