  1. All values are quoted as mean ± SD with 95% confidence intervals in square brackets. The table is divided into TM patients with no evidence of cardiac iron overload and age-matched healthy controls.
  2. RVEDVI = right ventricular end-diastolic volume index, RVESVI = right ventricular end-systolic volume index, RVSVI = right ventricular stroke volume index, RVEF = right ventricular ejection fraction, RVMI = right ventricular mass index, CO = cardiac output, CI = cardiac index
