Definition of abbreviations: BSA = body surface area; LV = left ventricular; LVED = left ventricular end diastolic; LVES = left ventricular end systolic; RV = right ventricular; RVED = right ventricular end diastolic; RVES = right ventricular end systolic; VMI = ventricular mass index.
Paired cardiac magnetic resonance imaging data are expressed as median (interquartile range) and were obtained for 23 patients.
