Cardiovascular structure	Quantifiable parameters
Left ventricle	Myocardial mass (g), ejection fraction (%), end-diastolic volume (ml), end-systolic volume (ml), stroke volume (ml) and the corresponding values indexed to body surface area, height or weight. Time to peak contraction and filling rates (both in s) and peak contraction and filling rates (both in ml/s). American Heart Association (AHA) myocardial segments: end-diastolic thickness (mm), end-systolic thickness (mm), thickening (mm), thickening (%). Strain: strain (%) and strain-rates (1/s) in three directions (radial [ERR], circumferential [ECC] and longitudinal [ELL]) and in systole and diastole and corresponding changes in angle caused by shear (ERC, ERL and ECL).
Right ventricle	Myocardial mass (g), ejection fraction (%), end-diastolic volume (ml), end-systolic volume (ml), stroke volume (ml) and the corresponding values indexed to body surface area, height or weight.
Left atrium	End-diastolic volume (ml), end-systolic volume (ml), stroke volume (ml), ejection fraction (ml) and left atrial diameters as typically measured by 2D-echocardiography approaches.
Right atrium	End-diastolic volume (ml), end-systolic volume (ml), stroke volume (ml), ejection fraction (ml) and right atrial diameters as typically measured by 2D-echocardiography approaches.
Aorta	Distensibility (1/mmHg) in ascending aorta, proximal descending and distal descending aorta; diastolic aortic dimensions (cm2): ascending aorta, proximal descending and distal descending aorta. Proximal, distal and total pulse wave velocity (m/s).
