In patients with severe aortic stenosis, low-gradient, low-flow and preserved ejection fraction (≥ 50%) (LG/LFp) the decrease in stroke volume index (Svi) could be due to diminished contractility. The aim of this study was to analyze if low Svi in patients with LG/LFp is related to a decrease in contractility.
