Values are means ± SD; n, number of patients. EDV, end-diastolic (ed) volume; ESV, end-systolic (es) volume; SLv, normalized measure of the sphericity index calculated in terms of the volume ratio of the LV volume and a theoretical sphere volume; SW, stroke work; S, surface area; ΔS, surface area change from end diastole to end systole; dσ*/dt_max, maximal rate of change of pressure-normalized stress; E_a, effective arterial elastance.

^aP < 0.05,

^bP < 0.01, and

^cP < 0.001 for 2-tail paired t-test used in comparing pre- and post-SVR values.
