Evaluation of left ventricular function on CT. Differences did not exist in end-diastolic (panel a), end-systolic (panel b), or stroke volume (panel c) between different study groups. While there was a significant difference in LV ejection fraction (panel d), subsequent pairwise differences were not significant.
Abbreviations: CT, computed tomography; NFHG, normal-flow high-gradient aortic stenosis; NFLG, normal-flow low-gradient aortic stenosis; pLFLG, paradoxical low-flow low-gradient aortic stenosis.
