⁎
Two participants in the MIS group were not administered gadolinium because of acute kidney injury.
BSA = body surface index; LVEDVi = left ventricular end-diastolic volume index; LVEF = left ventricular ejection fraction; LVESVi = left ventricular end-systolic volume index; RVEDVi = right ventricular end-diastolic volume index; RVEF = right ventricular ejection fraction; RVESVi = right ventricular end-systolic volume index; SV = stroke volume index.
p <0.05 is considered significant.
