- Functional parameters of systolic and diastolic function: LVEF, LV shortening fraction, left/right cardiac output and index, tricuspid and mitral annular excursions; parameters derived from the transmitral, transtricuspid, aortic or pulmonary flow, different systolic/diastolic timings and ratios (LV/RV TEI index, pre-ejection/ejection ratio, etc).
