  1. LV volumes were determined from both axial and short-axis (SA) images. Data from pre- and post-embolization CMR studies are combined.
  2. 1P < 0.05 with respect to CINE bSSFP. 2P < 0.05 with respect to axial 4D flow CMR. Abbreviations – EDV End-diastolic volume, ESV End-systolic volume, SV Stroke volume, EF Ejection fraction, CO Cardiac output.
