Overview

Retrospective analysis reveals CT aortic valve calcification density predicts mortality in aortic stenosis, indicating superior prognostic value.

Key Points

  • Aortic valve calcification density measured by multidetector computed tomography effectively identifies severe aortic stenosis and risk.
  • Computed tomography density yielded a hazard ratio of 1.59 for all-cause mortality, exceeding echocardiography values across 889 patients.
  • Retrospective analysis of Doppler echocardiography data highlights multidetector computed tomography thresholds of 300 to 500 Agatston units.
